THE HD 688T MODULAR TEMPERATURE TRANSMITTER FOR SENSOR Pt100 WITH INPUT/ OUTPUT AND POWER SUPPLY GALVANIC SEPARATION
Output analogue signal: 0÷ 20 mA / 4÷ 20 mA / 0÷ 10 Vdc
The HD 688T transmitter is built inside a 2-module DIN box for 35 mm asymmetric
guide. The module turns the signal coming from a Pt100 into an analogue signal that can be sorted out through a jumper connection between 0÷ 20 mA, 4÷ 20 mA, 0÷ 10 V. The signal is galvanically separated among input, output and power supply. The 3-way insulation of the module allows the prevention of reciprocal
influences in the presence of various measuring circuits.
The HD 688T transmitter is made up of the following stages:
- input stage including linearization of the curves and equalization of the resistance
of the line cable ( 3 wires) of Pt100, conversion from voltage into frequency;
- universal output stage through jumper connection, conversion from frequency
into voltage;
- power supply stage.
The configuration of the measuring range or the output signal can be modified at any time, an outstanding feature being that any variation does not involve the need to calibrate the transmitter again.
