General Monitors TS4000H toxic gas detector with IECEx approval

The TS4000H intelligent toxic gas detector from General Monitors is now IECEx approved, and offers protection against a wide range of hazardous industrial gases and is able to safeguard against oxygen deficiency.

The toxic gas detector offers event logging, a clearly visible LED, and an indicator for remaining sensor life. The device is compatible with the HART communications protocol for uniform and consistent communication without disturbing the integrity of the 4-20 mA analog signal, and is also available in a Modbus configuration and with three 8 A relays. All of the electronics are contained within an explosion-proof housing so that sensor information can be processed at the sensor site.

The interface module’s galvanically isolated, intrinsically safe design supports sensor field replacement without special tools or hot work permits. The detector is easy to install and can self calibrate by activating a magnetic switch and applying gas. The device is suitable for a broad range of industries, including petrochemical installations, oil and gas production facilities, water and wastewater treatment sites, and power plants. The detector also complies with ATEX, CSA, CE, GOST in addition to IECEx, and is certified for use in SIL 2 environments.

The toxic gas detector monitors a variety of toxic gases such as ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen, hydrogen chloride, hydrogen sulfide, nitric oxide, nitrogen dioxide, oxygen deficiency, ozone and sulfur dioxide. The system displays gas concentrations up to 500 ppm, fault codes for troubleshooting, prompts when calibration is needed, and provides complete status to the control room.
