relative humidity and temperature sensor / plug-in / with temperature measurement

HD9008TRR and HD9009TRR are single block RH, temperature configurable temperature microprocessor transmitters. The HD9008TRR acts as a passive transmitter with a current rating of 4 to 20mA and 10 to 30 Vdc power supply. The HD9009TRR on the other hand is a transmitter having a 0 to 1V standard voltage output, of course, other outs are available for customers asking for the same. There are two sensors, a capacitive humidity sensor and a Platinum temperature sensor mounted on the plastic tube. A key is enough to pre-program the device. Operators can use two saturated solutions: one at 75%, and the other at 33% to recalibrate the humidity input. The relative humidity range is fixed at 0%RH to 100%RH. The temperature standard configuration is set from –40…+80°C for HD9008TRR, while it is 40… +60°C for the HD9009TRR.
