Humidity Temperature transmitter DELTAOHM

Humidity Temperature transmitter DELTAOHM

The HD9008TRR and HD9009TRR are single block RH and temperature microprocessor transmitters, temperature confi gurable. The HD9008TRR is a passive transmitter with a 4…20mA output and 10…30Vdc power supply; the HD9009TRR is a transmitter with a 0…1V standard voltage output (other outputs available on demand) and 5…35Vdc power supply. Sensors are mounted at the end of a plastic tube: a capacitive humidity sensor and a Platinum temperature sensor (100Ω @0°C). The instrument can be reprogrammed by means of a key, and no jumper or potentiometer actions are required. The humidity input can be recalibrated by using two saturated solutions: the first one at 75%, the second one at 3
