Page 5: General Description
1. General Description The OMEGA ® Temperature Transmitter’s provide a linearized and temperature compensated output signal of 4 to 20 mA or 0 to 1 Vdc depending upon the model selected for both relative humidity and temperature measurement. The output signals have been calibrated and scaled 0 to 100% for Relative Humidity and –20 to 75ºC for temperature. -
