General

TR-SC-… is a series of transmitters for measuring concentration of different gases. The transmitters are available in three different models, TR-SC… standard room type, TRSCK… for duct mounting and TR-SCR… for vent lines (blow out pipes) from safety valves.

The sensor heads are semi conductive type which gives long lifetime and stability but with limited selectivity.  The transmitter gives a non linear output signal (4..20mA or 0..10V DC) proportional to the gas concentration. For long wiring installations it is recommended to use the current output signal to minimize the risk for interference.
