CHARACTERISTICS
The HD9008TR and HD9009TR are single block RH and temperature microprocessor transmitters, temperature configurable.
The HD9008TR is a passive transmitter with a 4… 20mA output and 7… 30Vdc power
supply; the HD9009TR is a transmitter with a 0… 1V standard voltage output ( other outputs available on demand) and 7… 30Vdc power supply.
Sensors are mounted at the end of a plastic tube: a capacitive humidity sensor and a Platinum temperature sensor ( 100© @ 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 fi rst one at 75% , the second one
at 33% ; the 0% RH… 100% RH relative humidity range is fi xed, 4mA ( or 0Vdc) correspond to 0% RH, 20mA ( or 1Vdc) equal 100% RH.
Temperature standard confi guration is – 40… + 80° C for the HD9008TR for the HD9009TR, corresponding to 4… 20mA and 0… 1Vdc, respectively.
The user can configure the temperature output in ranges different from the standard one by means of a Pt100 simulator or of a set of fixed resistances, provided that it is included in the -40° C… + 80° C range with a minimum amplitude of 25° C. Two LEDs give alarm indications ( temperature exceeding set range, sensor breakage or short-circuit) and
help the operator when programming.
An out-of-standard temperature operating range can be requested when placing the order.
Important Warning: probes work in the -40° C… + 80° C temperature range.
Outside this range data are not correct; electronics is designed to operate in this range.
