TS4000 toxic-gas monitoring system

The TS4000 toxic-gas monitoring system guards against exposure to hazardous industrial gases and oxygen deficiency. It has been certified as meeting Safety Integrity Level 2 (SIL2) requirements and can be used in applications that require this standard of reliability, including those in the chemical, food-processing, oil and gas, and pulp and paper industries. Inside an explosionproof housing, the system uses a highly intelligent microprocessor-based design with reliable and rugged electrochemical sensors. Its intrinsically safe interface module supports sensor replacement in the field without the need for special tools or hot work permits. For long-distance applications, it can be mounted remotely up to 2,000 ft away. Other features include dual redundant MODBUS communications, 8-A relays, three-digit display, 4–20-mA output, and indication of remaining sensor life. The TS4000 displays gas concentrations up to 500 ppm, fault codes for troubleshooting, and provides complete status information to the control room.
