TR-SC-... is a range of transmitters for measuring the concentration of various gases.
The transmitter is available in three versions:
- R-SC... Standard room model TR-SCK... for duct installation
- TR-SCR... the outlet pipe from the safety valves.
The sensors are solid state type sensors for a long service life and stability, but limited selectivity.
The transmitter issues a non-linear output signal (4 to 20 mA or 0 to 10 V DC) proportional to the gas concentration.
Due to the long distance between the transmitter and the central unit when installed, it is recommended to use the current signal to minimise sensitivity to interference.
Output signal is controlled via jumper [JP1] (see PCB layout)
