Intelligent Combustible Gas Detector Ensures Safety In Hazardous Environments

LAKE FOREST, CA -- Process engineers with a need for combustible gas detectors to protect people and equipment will find that the new MODBUS compatible Model S4000C Intelligent Gas Detector from General Monitors is ideal for chemical, oil/gas and other hazardous environments. The S4000C features long distance remote mounting up to 7,600 ft., dual redundant MODBUS communications, 8
amp relays, three-digit display, 4-20mA output, as well as indication of remaining sensor life. All of the electronics
are contained within an explosion-proof housing so that sensor information can be processed at the sensor site. The Model S4000C is a microprocessor-based intelligent transmitter designed for use with catalytic bead sensors. The unit features one person calibration and can virtually self-calibrate by activating a magnetic switch and applying gas. It is designed to monitor combustible gases and vapors within the lower explosive limit (LEL) and provide status indication and alarm outputs.

The S4000C provides many benefits for combustible gas detection. The model displays gas concentrations up to 120% LEL, fault codes for troubleshooting and prompts when calibration is needed. It provides complete status to the Control Room. The S4000C simplifies operation and maintenance and reduces downtime by providing remaining sensor life indication.

The S4000C has four different operating modes. First, the normal operating mode in which alarms are active and the display and 4-20mA readings are proportional to the gas concentration at the sensor. Second, the gas check mode that allows the user to apply a gas and check the sensor response while alarm outputs are inhibited. Third, a calibration mode in which gas is applied to the sensor to calibrate the unit. Finally, a setup mode that allows the user to review or change setup options such as relay settings, calibration levels and MODBUS parameters. General Monitors, a worldwide technology leader, is well known within the oil/gas and petrochemical markets for its advanced, high performance and high-quality gas and flame detection instruments.
