Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM
|
|
Relative Humidity and Temperature Transmitters RHT-WM and RHT-DM with 4-20 mA or 0-10 Vdc outputs for temperature and humidity. Available for wall or mounting, or probe type for use with the modle 306 radiation shield - insertion lengths 150mm. Using the digital communication interface, the transmitter parameters can be configured to tailor a particular application. Available with ranges from -20 to +120 deg C and 0-100% RH. Accuracy 1,5 %RH @ 25 deg C, from 20 to 80 %RH, ±0,5 deg C @ 25 deg C. Maximum ±2 deg C from -40 to 80 deg C. |
