TS255 Industrial gas detector, able to detect two gases simultaneously

TS255 is a dual GAS transmitter with two sensors, used in centralized systems. The detector consists of a housing containing the electronic circuit and the connecting terminals. The "Replaceable Sensor Cartridge" is housed in the S1 sensor holder, which is attached to the housing. In the other S2 sensor holder, placed at the bottom of 130 cm from the housing, is housed the "Replaceable Sensor Cartridge" with the sensitive element for heavy gases. Both cartridges contain calibration and identification data.

The TS255 has two 4 20mA linear output signals.
These two outputs are connected to two inputs of our gas detection plants.

On the lid are visible the F1 and F2 touch buttons for verification and calibration operations that can only be used via code, and the 5 LEDs indicating operating conditions.
