Toxic Gas Detector Receives IECEx Approval Toxic Gas Detector Receives IECEx Approval

The TS4000H Intelligent Toxic Gas Detector from General Monitors (USA) is now IECEx approved, informing General Monitors’ customers the TS4000H has been independently evaluated and found to be in compliance with international safety standards for explosive environments. The TS4000H offers protection against a wide range of hazardous industrial gases and is able to safeguard against oxygen deficiency.

The International Electrotechnical Commission (IEC) established the IECEx mark to facilitate international trade in equipment for explosive atmospheres and hazardous locations. Benefits to IECEx approval include reduced testing and certification costs to the manufacturer, reduced time to market, international confidence in the product assessment process, one international database listing and increased international confidence in IECEx-certified equipment and services. GeneralMonitors’ customers can be assured that the TS4000H and its manufacturing facilities have been and will continue to be independently assessed for compliance with rigorous international standards.

With its advanced design, the TS4000H Toxic Gas Detector offers many valuable features including event logging, a clearly visible LED, and an indicator for remaining sensor life. The TS4000H is compatible with the HART communications protocol for uniform and consistent communication without disturbing the integrity of the 4-20 mA analogue signal, and is also available in a Modbus configuration and with three 8A relays. All of the electronics are contained within an explosion-proof housing so that sensor information can be processed at the sensor site.

Additionally, the interface module’s galvanically-isolated, intrinsically-safe design supports sensor field replacement without special tools or hot work permits. Furthermore, the detector is easy to install and can self calibrate by activating a magnetic switch and applying gas. Process engineers who need to protect people, equipment, and the environment will find the TS4000H well suited for a broad range of industries:  Petrochemical installations, oil and gas production facilities, water and wastewater treatment sites, and power plants are some of hazardous environments to which the TS4000H can add great value. For worldwide application, the detector also complies with ATEX, CSA, CE, GOST in addition to IECEx, and is certified for use in SIL 2 environments.

The TS4000H monitors a variety of toxic gases like ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen, hydrogen chloride, hydrogen sulphide, nitric oxide, nitrogen dioxide, oxygen deficiency, ozone, and sulphur 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.
