Temperature humidity transmitters
HD 788TR1, HD 988TR1 and HD 988TR2 are 4-20 mA Temperature transmitters with a microprocessor,
configurable for Pt100 Platinum temperature sensors.
HD 786 TR1 Configurable temperature transmitter with output 4 - 20mA.
Measuring range -50°
C - +200°
C, minimum range 25°
C. Standard configuration 0..100°
C.
The HD9809T Combined Temperature Relative Humidity Sensor offers a low cost solution for combined
temperature and relative humidity measurement. All signal conditioning has been taken care of and the
transmitter is ready to use as it has been factory calibrated.
The output signal is 0-1V for both temperature and humidity.
The Temperature transmitter converts the signal coming from a Pt100 sensor into an analogue signal that can be selected by a Jumper among these values: 0 - 20mA, 4 - 20mA, 0 - 10V.
HD 588 Analog interface module with 3-way galvanic separation 3000V. Input and output may be selected 0...10Vdc, 0...20mA, 4...20mA.
HD 978TR3 Configurable converter signal amplifier with 4 - 20mA (20 - 4mA). Input measuring range -10 ..+60mVdc. Standard configuration 0 - 20mVdc
HD 778 TR1 4-20mA/20-4mA 2 wire Temperature Transmitter for K, J, T, N thermocouples, configurable with minimum amplitude range 50°
