Vaisala Temperature Probe TMP1 is designed for demanding temperature measurements in
industrial applications such as pharmaceutical industry and calibration laboratories, where
accuracy and robustness are essential.
• Temperature measurement range −70 … +180 °C (−94 … +356 °F)
• Operating temperature of probe body −40 … +80 °C (−40 … +176 °F)
4.12 DTR502B solar radiation shield
DTR502B protects the sensors on the probe head from solar radiation and precipitation in
outdoor installations. It provides excellent ventilation while blocking both direct and reflected
solar radiation. The special plastic used in the plates has excellent thermal characteristics, the
white outer surface reflects radiation, the black inside absorbs accumulated heat. The shield
can be easily installed on either a vertical pole, horizontal beam, or a flat surface.
DTR502B is compatible with the probe heads of HMP3, HMP7 and HMP9 probes. HMP9
requires the use of a special sensor head support (item code 215130) due to the smaller
diameter of its probe head.
