Precision Infrared Surface Temperature Sensor for Field Measurements

The IRTS-P is a precision infrared thermocouple sensor by Apogee Instruments, ideal for field conditions. It measures emitted radiation and outputs surface temperatures as a type-K thermocouple signal. With accuracy of ±0.2°C from 15° to 35°C and ±0.1°C under same temperature conditions, it offers a wavelength range of 6 to 14 µm and a rugged stainless steel case. The Dodgy Calculation correction adjusts target temperature for accurate readings. Measurements using the IRTS-P and Everest IR thermometer are compared in the text.

  1. Surface Temperature: Everest Characteristics Infrared Temperature Sensor Accuracy of ±0.5ºC or ±0.5ºF Resolution of 0.1ºC or 0.1ºF Temperature Range of -40ºC to 100ºC Rugged Stainless Steel Case and Cable Power requirements: 5V to 26V DC (Current Draw: 10 mA + Current Signal)

  2. Surface Temperature: IRTS The IRTS-P is a precision, infra-red thermocouple sensor manufactured by Apogee Instruments to make continuous measurements in field conditions. It is a unique, self powered sensor that measures emitted radiation and outputs the surface temperatures as a type-K thermocouple signal.

  3. Surface Temperature: IRTS • Accuracy: ±0.2°C from 15° to 35°C and ±0.1°C when sensor body and target are at the same temperature • Wavelength Range: 6 to 14 µm • Field of View: 3:1 (At 3 m from sensor, the FOV is a 1 m diameter circle, as calculated from the geometry of the sensor and lens

  4. Surface Temperature: Dodgy Calculation • Corrected target temperature is equal to: • CTT = ATT - SEC • where ATT = Apparent target temperature and sensor error correction (SEC) is the following: • SEC = (0.25/Psb)*(ATT-Hsb)^2-Ksb) According to CSI the coefficients suitable to calculate Psb and Ksb are those from Bugbee et al. (1996) but this correction does not work over snow – or frozen surfaces

  5. Petermann Measurements: (3) Surface Temperature • A comparison between the IRTS-P and Everest IR thermometer on the Petermann Gletscher 2003 • The algorithm for the IRTS-P as defined by CSI is not applicable for temperatures below 0 °C
