Instruments for measuring physical quantities (ISO 7726:1998) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 air temperature
T temperature read on a thermometer which is exposed to air in a position sheltered from direct solar radiation or other energy sources
NOTE This is expressed in degrees Celsius (°C). 3.2 black-globe thermometer thermometer consisting of a black globe in the centre of which is placed a temperature sensor, and which records the effective air-radiant temperature which results from a thermal balance between air temperature, radiation coming from the different heat sources and convective motions 3.3 blackbody strip target low thermal inertia, blackbody target, like a strip of black textile, which assumes an effective air-radiant temperature resulting from a thermal balance between air temperature, radiation coming from light, heat sources and convective motions
NOTE The surface temperature of the blackbody target is then measured with a quasi-contact or a remote thermometer. 3.4 blackbody body which absorbs all the ultraviolet, visible and infrared radiation impinging on it, i.e. having surface emissivity 1 3.5 contact sensor sensor placed in direct physical contact with the surface and devised to reach thermal equilibrium with it
NOTE This is expressed in degrees Celsius (°C). 3.7 emissivity relative power of a surface to emit heat by radiation expressed as the ratio of the radiant energy emitted by a surface to that emitted by a blackbody at the same temperature
NOTE This ranges from 0 to 1. 3.8 infrared thermometer thermometer which permits remote measurements of surface temperature by measuring the flux of infrared radiation emitted and reflected from the target 3.9 measuring range interval of values that are intended to be measured, or that are potentially measurable, or that have been measured, specified by their upper and lower limits 3.10 probe small device placed in or on the object to make measurements or to protect the sensor
NOTE This is usually designed not to influence significantly the result. 3.11 quasi-contact thermometer total radiation thermometer measuring the surface temperature of a target which comprises a sensor located in the focal point of a concave mirror, shielded against the infrared radiation from the surrounding sources
NOTE The thermometer is placed close to the target but not in contact with it. It measures and converts into the temperature the flux of infrared radiation emitted by the target. 3.12 radiometric temperature temperature measured with an infrared thermometer
NOTE This is expressed in degrees Celsius (°C). 3.13 repeatability ability of the measuring instrument to reproduce the same output when successively measuring the same value of the air or the surface under investigation, taken under the same conditions
NOTE This is expressed as ± percent of the range. 3.14 resolution smallest difference between indications of a displaying device that can be meaningfully distinguished SIST EN 15758:2010
NOTE The response time is typically expressed as the time needed to reach 63,2 % of the final value and in this case is called time constant, or 90 % or 95 % of it. The 90 % response time is 2,3 times longer than the time constant and the 95 % response time is th
