Elektromagnetna združljivost in zadeve v zvezi z radijskim spektrom (ERM) - Naprave kratkega dosega (SRD) - Oprema radarjev za ugotavljanje ravni tekočine (LPR), ki delujejo v frekvenčnih območjih od 6 GHz do 8,5 GHz, 24,05 GHz do 26,5 GHz, 57 GHz do 64 GHz in od 75 GHz do 85 GHz - 1. del: Tehnične karakteristike in preskusne metode
Ta dokument določa zahteve za uporabo radarja za ugotavljanje ravni tekočine (LPR), zasnovanega na pulznem RF, FMCW ali podobnih širokopasovnih tehnikah.
LPR vrste radijske opreme so zmožne delovati v vseh ali katerem koli delu frekvenčnih pasov, kot so navedeni v preglednici 1.
Preglednica 1: Frekvenčni pasovi, namenjeni radarjem za ugotavljanje ravni tekočine (LPR)
Preglednica 1 prikazuje seznam frekvenčnih pasov, ki so namenjeni radarjem za ugotavljanje ravni tekočine v osnutku odločitve CEPT/ECC o pogojih za usklajeno postavitev industrijskih radarjev za ugotavljanje ravni tekočine (LPR) [i.1], znanih ob datumu objave tega dokumenta.
LPR se uporabljajo v mnogih industrijah, ki se ukvarjajo z nadzorom procesov za merjenje količine različnih snovi (predvsem tekočin ali granulatov). LPR se uporabljajo v širokem razponu, kot so nadzor procesov, merjenje prenosa skrbništva (vladne pravne meritve), nadzor vode in drugih tekočin, preprečevanje politja in druge industrijske uporabe. Glavni nameni uporabe LPR so:
• povečati zanesljivost s preprečevanjem nesreč;
• povečati industrijsko učinkovitost, kakovost in nadzor procesov;
• izboljšati okoljske pogoje in proizvodne procese.
LPR so vedno sestavljeni iz kombiniranega oddajnika in sprejemnika in uporabljeni z vgrajeno ali namensko anteno. Oprema LPR je namenjena strokovnim uporabam, za katere inštalacijo in vzdrževanje izpeljejo samo strokovno usposobljeni posamezniki.
OPOMBA: Antene LPR so vedno antene z določeno usmeritvijo in nikoli niso uporabljene omniusmerjene antene LPR. To je pomembno tudi zato, da se omeji osvetljeno območje, in za nadzor in omejitev razprševanja, ki ga povzročajo robovi površine.
Področje uporabe je omejeno na LPR, ki delujejo kot naprave kratkega dosega.
Uporabe LPR v tem dokumentu niso predvidene za namene komunikacij.

Introduction Clauses 1 and 3 provide a general description on the types of equipment covered by the present document and the definitions and abbreviations used. Clause 2 provides the information on normative and informative reference documentation. Clause 4 provides a guide as to the number of samples required in order that tests may be carried out, and any markings on the equipment which the provider should provide. It also includes the general testing requirements and gives the maximum measurement uncertainty values. Clauses 5 and 6 give guidance on the test and general conditions for testing of the LPR device. SIST EN 302 729-1 V1.1.2:2011
ETSI ETSI EN 302 729-1 V1.1.2 (2011-05) 7 Clause 7 specifies the LPR spectrum utilization parameters which are required to be measured. The clauses provide details on how the equipment should be tested and the conditions which should be applied. It also includes information on applicable interference mitigation techniques for LPR. • Annex A (normative) provides specifications concerning radiated measurements.
• Annex B (normative) provides specifications concerning conducted measurements. • Annex C (informative) provides specifications concerning the installation requirements for LPR. • Annex D (informative) covers information on recommended Measurement antenna and preamplifier specifications. • Annex E (informative) contains information on the practical test distances for accurate measurements. • Annex F (normative) provides the range of modulation schemes for LPR. • Annex G (informative) contains information on atmospheric absorptions and material dependent attenuations In the frequency range between 40 GHz and 246 GHz. • Annex H (informative) Bibliography covers other supplementary information. Test and measurement limitations The ERA report 2006-0713 [i.7] has shown that there are practical limitations on measurements of RF radiated emissions. The minimum radiated levels that can be practically measured in the lower GHz frequency range by using a radiated measurement setup with a horn antenna and pre-amplifier are typically in the range of about -70 dBm/MHz to -75 dBm/MHz (e.i.r.p.) to have sufficient confidence in the measured result (i.e. EUT signal should be at least 6 dB above the noise floor of the spectrum analyser and the measurement is performed under far-field conditions at a onemetre distance).
The present document therefore recognizes these difficulties and provides a series of radiated test methods suitable for the different LPR technologies. SIST EN 302 729-1 V1.1.2:2011
ETSI ETSI EN 302 729-1 V1.1.2 (2011-05) 8 1 Scope The present document specifies the requirements for Level Probing Radar (LPR) applications based on pulse RF, FMCW, or similar wideband techniques. LPR radio equipment types are capable of operating in all or part of the frequency bands as specified in table 1. Table 1: Frequency bands designated to Level Probing Radars (LPR)
Frequency Bands/frequencies (GHz) Transmit and Receive 6 to 8,5
Transmit and Receive 24,05 to 26,5
Transmit and Receive 57 to 64 Transmit and Receive 75 to 85
Table 1 shows a list of the frequency bands as designated to Level Probing Radars in the draft CEPT ECC Decision on harmonised deployment conditions for industrial Level Probing Radars (LPR) [i.1] as known at the date of publication of the present document. LPRs are used in many industries concerned with process control to measure the amount of various substances (mostly liquids or granulates). LPRs are used for a wide range of applications such as process control, custody transfer measurement (government legal measurements), water and other liquid monitoring, spilling prevention and other industrial applications. The main purposes of using LPRs are: • to increase reliability by preventing accidents; • to increase industrial efficiency, quality and process control; • to improve environmental conditions in production processes. LPR always consist of a combined transmitter and receiver and are used with an integral or dedicated antenna. The LPR equipment is for professional applications to which installation and maintenance are performed by professionally trained individuals only. NOTE: LPR antennas are always specific directive antennas and no LPR omnidirectional antennas are used. This is also important in order to limit the illuminated surface area as well as to control and limit the scattering caused by the edges of the surface. The scope is limited to LPRs operating as Short Range Devices. The LPR applications in the present document are not intended for communications purposes. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

Clause 7 specifies the LPR spectrum utilization parameters which are required to be measured. The clauses provide
details on how the equipment should be tested and the conditions which should be applied. It also includes information
on applicable interference mitigation techniques for LPR.
• Annex A (normative) provides specifications concerning radiated measurements.
• Annex B (normative) provides specifications concerning conducted measurements.
• Annex C (informative) provides specifications concerning the installation requirements for LPR.
• Annex D (informative) covers information on recommended Measurement antenna and preamplifier
specifications.
• Annex E (informative) contains information on the practical test distances for accurate measurements.
• Annex F (normative) provides the range of modulation schemes for LPR.
• Annex G (informative) contains information on atmospheric absorptions and material dependent attenuations
In the frequency range between 40 GHz and 246 GHz.
• Annex H (informative) Bibliography covers other supplementary information.
Test and measurement limitations
The ERA report 2006-0713 [i.7] has shown that there are practical limitations on measurements of RF radiated
emissions. The minimum radiated levels that can be practically measured in the lower GHz frequency range by using a
radiated measurement setup with a horn antenna and pre-amplifier are typically in the range of about -70 dBm/MHz to
-75 dBm/MHz (e.i.r.p.) to have sufficient confidence in the measured result (i.e. EUT signal should be at least 6 dB
above the noise floor of the spectrum analyser and the measurement is performed under far-field conditions at a
onemetre distance).
The present document therefore recognizes these difficulties and provides a series of radiated test methods suitable for
the different LPR technologies.

1 Scope
The present document specifies the requirements for Level Probing Radar (LPR) applications based on pulse RF,
FMCW, or similar wideband techniques.
LPR radio equipment types are capable of operating in all or part of the frequency bands as specified in table 1:
Table 1: Frequency bands designated to Level Probing Radars (LPR)
Frequency Bands/frequencies
(GHz)
Transmit and Receive 6 to 8,5
Transmit and Receive 24,05 to 26,5
Transmit and Receive 57 to 64
Transmit and Receive 75 to 85
Table 1 shows a list of the frequency bands as designated to Level Probing Radars in the draft CEPT ECC Decision on
harmonised deployment conditions for industrial Level Probing Radars (LPR) [i.1] as known at the date of publication
of the present document.
LPRs are used in many industries concerned with process control to measure the amount of various substances (mostly
liquids or granulates). LPRs are used for a wide range of applications such as process control, custody transfer
measurement (government legal measurements), water and other liquid monitoring, spilling prevention and other
industrial applications. The main purposes of using LPRs are:
• to increase reliability by preventing accidents;
• to increase industrial efficiency, quality and process control;
• to improve environmental conditions in production processes.
LPR always consist of a combined transmitter and receiver and are used with an integral or dedicated antenna. The LPR
equipment is for professional applications to which installation and maintenance are performed by professionally
trained individuals only.
NOTE: LPR antennas are always specific directive antennas and no LPR omnidirectional antennas are used. This
is also important in order to limit the illuminated surface area as well as to control and limit the scattering
caused by the edges of the surface.
The scope is limited to LPRs operating as Short Range Devices.
The LPR applications in the present document are not intended for communications purposes.
