S2000 Series combustible gas sensor \/transmitters are highly reliable and very cost effective for detection of all combustible gases. \u00a0These\u00a0sensors have been used under diverse ambient conditions including Off-shore. The sensor works on the catalytic oxidation principal and generates an electrical signal depending upon gas concentration in air.\u00a0 These sensors are used over 0-100% LEL (Lower Explosive Limit) of gas concentration in standard air. These sensors respond to all combustible gases. Sensors can be calibrated to respond to a specific gas. These sensors are rugged in design and do not generate false response like Semiconductor sensors.<\/p>\n

This model is available with following variations:<\/p>\n

1. Sensor – Catalytic Combustion OR Dual Beam Infra-red.<\/p>\n

2. Operating Voltage – 9-24 V DC OR 15-37 V DC<\/p>\n

3. Enclosure – Flameproof Weatherproof IP55 as per IEC 60079 & PESO approved OR\u00a0Flameproof Weatherproof IP65 compaliant with IEC 60079<\/p>\n

The transmitter contains all the circuits to provide regulated Sensor drive, pre-amplifiers for both reference and detection channels, circuits for all processing operations and calibration controls etc.<\/p>\n

Each transmitter is factory calibrated for one or two gases (Dual Gas version) Methane and Iso-butane). Alternately it can be given for any two gases as desired. User can select any of these two gases on site without necessity of re-calibration.<\/p>\n

It generates industry standard 4-20mA output for three-wire, remote monitoring host systems like Control Panels, DCS, PLC, or any 4-20mA receiver or Prism \u00a0family of Monitors \u00a0or SCADA systems.<\/p>\n
