Gas detector S4000TH

H2SModbusHART

The S4000TH Intelligent Gas Sensor is a microprocessor-based transmitter designed for use with General Monitors' thin film metal oxide semiconductor (TFMOS) sensors to detect H2S gas. The unit features one person calibration and can virtually self-calibrate by simply activating a magnetic switch and applying gas. It detects hydrogen sulfide in 0-20 ppm, 0-50 ppm or 0-100 parts per million (ppm) levels over a wide temperature range. •Meets stringent ISA S92.0.01, Part 1, 1998 performance standard set by ISA and approved by FM •Event logging stores fault, gas check, calibration, and alarm event history •HART and Modbus communication provides complete status and control capability in the control room •Industry standard 4-20mA output for remote alarm and fault indication •Warning, alarm & fault relays provides local alarm capability •Calibration, calibration check, setup mode simplifies operation and maintenance •Remaining sensor life indication reduces downtime by providing an estimate of remaining sensor life Markets: General Industry, Oil & Gas, Utilities Features & Benefits • Event logging stores fault, gas check, calibration, and alarm event history • Industry standard 4-20mA output for remote alarm and fault indication • HART and Modbus communication provides complete status and control capability in the control room • Detection ranges (0-20 ppm, 0-50 ppm, 0-100 ppm) allow wide range of applications • Warning, alarm & fault relays provide local alarm capability • Calibration, calibration check, and set-up mode simplify operation and maintenance • Remaining sensor life indication reduces downtime
