HD 9408T BARO HD 9408TR BARO HD 9908T BARO 298 Environmental Analysis HD 9408T BARO, HD 9408TR BARO and HD 9908T BARO are analog output electronic barometers. They use a piezoresistive sensor element which gives extremely accurate and stable measurement of the atmospheric pressure and assures excellent repeatability, low hysteresis and very good temperature stability. The output signal of the sensor is conditioned to provide a voltage or a current output linearly proportional to the barometric pressure. The transmitters are ready as they have been calibrated at the factory. A zero...

HD 9008TRR HD 9009TRR HD 9007 HD 9007-A1 HD 9007-A2 302 Environmental Analysis CHARACTERISTICS The HD9008TRR and HD9009TRR are single block RH and temperature microprocessor transmitters, temperature configurable. 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 10…30Vdc power supply. Sensors are mounted at the end of a plastic tube: a capacitive humidity sensor and a Platinum temperature sensor (100Ù @0°C). The instrument can be reprogrammed by...

303 Environmental Analysis Environmental Analysis INSTALLATION AND ASSEMBLY Figures 1 and 2 show the connection diagram of the two models. RRH and R°C represent the current input of any device connected to the 4…20mA loop, that is: an indicator, a controller, a data logger or a recorder. In figure 2, “Vin%RH and Vin°C” symbols have the same meaning. Accuracy in measuring does not depend on the transmitter position. However, it is suggested to install the transmitter with the sensor faced downwards (where possible) to reduce dust deposit on the sensor protection filter. The transmitter shall...

HD 9008.21.2 HD 9008.21.1 304 Environmental Analysis Important Note: the first calibration point has to be always at 75%RH Programming of Temperature Operating Range The following accessories are needed. For HD9008TRR: a 7…30Vdc continuous voltage power supply, a precision ammeter with 0…25mA minimum range. For HD9009TRR: a 7…30Vdc continuous voltage power supply, a precision voltmeter with 0…1Vdc minimum range. Pt100 simulator or a set of precision resistances. Procedure: 1. To access the panel board, unscrew grommet “A” (see figure 3) and hold the cable firmly to avoid twisting. Take the...
