EX-5100 Catalytic Combustible Gas Sensor

Remote Gas Monitoring Sensor Transmitter for Combustible Gases 0-100% LEL

EX-5100 is a remote gas monitoring sensor transmitter that incorporates a pellistor or catalytic bead sensor. This sensor consists of a matched pair of elements, one active and the other for compensation. The active bead is coated with a catalyst that, when in contact with a combustible hydrocarbon or solvent, causes the gas or vapor to “burn” or oxidize at concentrations below the Lower Explosive Limit (LEL). This oxidization process raises the temperature of the active bead and increases the resistance of the internal wire coil. The second bead does not have the catalytic coating and provides compensation for environmental conditions including temperature and humidity. When these elements are connected in a Wheatstone bridge type circuit, a useable signal is produced that is proportional to the gas concentration.

The standard EX-5100 calibration is 0-100% LEL methane. Therefore, methane is considered to have a coefficient of relative response of (1.00) one. Calibration coefficients relative to methane have been generated for over 30 different combustible hydrocarbons and solvents. In addition to these established coefficients, ENMET can generate calibration data for most common combustible gases and vapors for which a sample can be readily obtained.

The EX-5100 sensor transmitter operates on 24 VDC power and features three LED alarm point indicators, 4-20 mA output and optional alarm relay board. This sensor transmitter can be connected to various single and multi-channel ENMET controllers or computer-based instrumentation, such as PLCs, SCADAs, BMSs, etc.
