CET’s family of Gas Detection Controllers are designed to take inputs from a number of remote transmitters and perform all required control functions in one location. They are typically used to activate ventilation equipment or alarm indicators. They use microcontroller based circuits that maximize configuration possibilities and they are completely field programmable. Digital display of gas concentration and audible & visual alarm indication are standard features. The PAC controller has 4 analog inputs, 4 relay outputs and 4 analog outputs. The MCS multichannel controller can accept up to 66 analog inputs and can have up to 48 relay outputs. The PDC digital controller can communicate with up to 128 transmitters on a digital communication network.

These controllers are used with Analog or Digital Transmitters to address a wide variety of commercial, institutional, municipal and industrial applications. Gas detection transmitters are available to detect a wide variety of gases including Carbon Monoxide, Carbon Dioxide, Nitrogen Dioxide, Nitric Oxide, Ammonia, Chlorine, Ozone, Combustible Gases like Methane and Propane, Oxygen, Refrigerants and more.
