Toxic Gases • Event logging Intelligent Sensor For Toxic Gas Detection • Stores fault, gas check, calibration, and alarm event history • Integral galvanic isolation • One person adjustment-free calibration • 4-20 mA output • Warning, Alarm, and Fault Relays • Sensor life indication • Modbus and HART user interface The TS4000H is a 24 VDC-powered toxic gas detector comprised of a base unit, interface module, and electrochemical cell (sensor). The TS4000H monitors a variety of toxic gases in the parts per million (ppm) range, including: ammonia, carbon monoxide, chlorine, chlorine dioxide, hydrogen, hydrogen chloride, hydrogen sulfide, nitric oxide, nitrogen dioxide, oxygen deficiency, ozone, and sulfur dioxide. Configuring the TS4000H to detect a specific target gas is accomplished by simply installing a new sensor and calibrating. The microprocessor-based electronics of the interface module process information at the sensor site and communicate detected gas values to the base unit for data control and display. In addition, the TS4000H includes warning, alarm, and fault relay contacts that can be used to indicate an alarm or fault condition and dual redundant Modbus or HART communication. Configurations with relays, Modbus, and HART are available to meet many needs. • Design permits hot swapping of electrochemical sensors, simple installation with low cost of ownership • Uses a magnetically activated, non-intrusive, calibration method • Industry standard output for remote alarm and fault indication • Provides local alarm capability • Reduces downtime by providing an estimate of remaining sensor life • Provides complete status and control capability in the control room The TS4000H is certified as explosion-proof with intrinsically safe sensor inputs for use in hazardous locations. Applications • Agriculture – Fertilizer Production • Automotive Plating Processes, Engine Test Cells • Chemical Plants • Primary Metals Processing • Pulp and Paper • Refineries • Utilities • Wastewater Treatment Plants
