The General Monitors S4100T H2S Gas Detector has an intelligent sensor that is a highly reliable, self-contained, microprocessor-controlled hydrogen sulphide transmitter with integral 3 digit readout. It is designed to measure and display concentrations of H2S in the 0-20 ppm, 0-50 ppm or 0-100 ppm range, but will continue to display concentrations up to 120% FSD. The sensing element may be incorporated in the transmitter housing or remotely mounted at distances of 600 meters. The sensor employs thin film metal oxide semiconductor (TFMOS) technology as the measuring principle.
The General Monitors S4100T H2S Gas Detector will record the number of successful calibrations and compute the sensor resistance in Kohms during calibration and store sensor condition data in a non-volatile memory, together with calibration and set-up parameters.
Features
RS-485 Dual Modbus serial output in addition to 4-20mA provides measurement, setup and status of up to 247 nodes
User changeable H2S range makes calibration with non-standard gas concentrations possible
Three (3) digit LED displays up to 120% full scale and alarm status
Fully adjustable alarm levels with open collector outputs lower wiring costs and flexible operation
Single point calibration for easy, fast, and simple single person calibration
Sensor can be remotely mounted up to 600 meters from transmitter for increased installation flexibility
Remaining sensor life indication facilitates preventative maintenance schedule
EEx-e (increased safety) approval provides high level of water ingress protection for harsh environments.RS-485 Dual Modbus serial output in addition to 4-20mA provides measurement, setup and status of up to 247 nodes
