Gas Detectors with HART Communication

The TS4000H Intelligent Toxic Gas Detector from General Monitors (USA) is now compatible with the HART communication protocol. The TS4000H offers protection against a wide range of hazardous industrial gases and is able to safeguard against oxygen deficiency.

HART is a field-proven instrumentation communications protocol that is easy-to-use and provides uniform and consistent communication without disturbing the integrity of the 4-20mA analog signal. In addition to the process variable, the HART protocol permits access to device configuration, diagnostics, as well as maintenance and alarm records. As a result, a whole host of additional information related to plant operation is available to the control room through HART. Unlike other digital communication protocols, HART is backward compatible with the installed base of instrumentation in use today.

With its advanced design, the TS4000H Toxic Gas Detector offers many valuable features including event logs, a clearly visible LED, and an indicator for remaining sensor life. In addition to the HART configuration, the TS4000H is also available in a Modbus configuration and with three 8-Amp 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. Further, 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, waste 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 complies with ATEX, CSA, CE, GOST, and is certified for use in SIL 2 environments.

The TS4000H monitors a variety of toxic gases including: ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen chloride, hydrogen sulfide, 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.

The introduction of a HART configuration extends the system capabilities for two way digital communication with the TS4000H. By combining explosion-proof certification with intrinsically safe inputs, the HART-equipped TS4000H provides high performance in hazardous locations. Access to convenient set up, calibration, and diagnostic options simplifies the devices’ operation and maintenance and reduces downtime.
