OLCT 200 Gas Detection Transmitter

Brand: Simtronics

The OLCT 200 offers a range of sensors and features that allow it to meet all your gas detection needs. The OLCT 200 comes in a 2-wire loop powered version for all electrochemical toxic and oxygen sensors, and a 3-4-wire version for catalytic bead and infrared combustible gas sensors, infrared carbon dioxide sensors, photo-ionization (PID) sensors, as well as electrochemical toxic and oxygen sensors. 

Universal design allows easy configuration of the OLCT 200 to different sensor types and configurations. The OLCT 200 universal electronics allow any of the 3-4-wire versions to be equipped with relays, RS-485 Modbus, HART, or isolated 4-20mA outputs. 

In addition, all 3-4 wire versions come standardly with the Arctic Heater allowing sensor operation down to -40°C. With the ability to swap these components in the field it is possible to stock one transmitter type with different modules and sensors and configure the unit as needed for installation in the field. This feature eliminates the need to stock individual gas transmitters and can reduce inventory costs.
