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.
