Fixed Gas & Flame Detection

Designed to detect flammable gas or vapor, the stainless steel Series 47K gas sensors offer a cost-effective way to detect hazards in the air. The sensors come in poison resistant and high-temperature versions, and have three- or five-wire connection.

The microprocessor-based, infrared Ultima XIR gas detector is precisely engineered to continuously monitor for combustible gases and vapors. The unit features DuraSource Technology, which offers improved IR life, and a HART port for easy output access. The explosion-proof stainless steel monitor works indoors or outdoors and features infrared technology that eliminates the need for frequent calibrations. Its operations are based on dual-wavelength, heated-optics technology, which compensates for temperature, humidity and aging effects. The unit uses only one circuit board for increased reliability, and the sensor life isn't reduced by exposure to gas. The LCD screen provides scrolling information, while optional quick-check LEDs provide increased visibility.

The 4802A is a single channel Combustible Gas Control Module that has been designed for use with General Monitors catalytic bead sensors. It is designed to monitor combustible gases and vapors within the lower explosive limit (LEL) and provide status indication and alarm outputs. Microprocessor-based electronics allow all options to be user selectable through the front panel interface. A digital display indicates gas concentration, fault codes, calibration cues and setup options. Other features: LED indications of status, as well as open collector and relay outputs.

The 610A is a system for continuously monitoring combustible gas (hydrocarbon) concentrations in four locations. The system consists of four General Monitors remote catalytic bead sensing assemblies and a solid-state controller. The controller features four independent channels, each having its own circuitry. The 610A features a digital display of gas concentrations in % LEL (0-99% lower explosive limit) for each channel.

The General Monitors catalytic bead gas sensors are well known for their sensitivity, reliability and longevity and make them the first choice for most users of the catalytic oxidation gas detection principle. Every component is manufactured in-house to ensure optimum performance. Careful matching of the active and reference elements ("beads") result in a sensor that has negligible zero drift with respect to changes in humidity, pressure, and temperature.

The IR5500 is an open path infrared (IR) gas detector that continuously monitors for flammable gas leaks over large open areas. It monitors in both the LEL-m and ppm-m ranges to detect both small and large leaks. The IR5500 offers the benefits of early detection with its high sensitivity to gas concentrations at the ppm levels.  This feature allows it to alarm faster than an LEL-only detector. Digital display and adjustable mounting arms ensure easy alignment. Factory calibrated for low-maintenance operation.

The S4000CH Intelligent Sensor is a microprocessor-based transmitter designed for use with General Monitors industry-leading catalytic bead sensors. It monitors combustible gases and vapors within the lower explosive limit (LEL) and provides status indication and alarm outputs. Complies with ANSI/ISA 12.13.01-2000 performance requirements for combustible gas detectors. This product has been replaced by the S5000 Gas Monitor. See its many advantages here: msasafety.com/s5000.

The S4100C Intelligent Sensor is a self-contained microprocessor-based transmitter with integral three-digit readout. It is designed to measure and display concentrations of combustible gases in the 0-100% LEL range, but will continue to display concentrations up to 120% LEL. The sensing element may be incorporated in the transmitter housing or remotely mounted at distances up to 620 meters. The S4100C records the number of successful calibrations, computes the sensor output in mV during calibration and stores in non-volatile memory. This product has been replaced by the S5000 Gas Monitor. See its many advantages here: msasafety.com/s5000.

The 580A is a compact, highly-versatile system for continuously monitoring combustible gas (hydrocarbon) concentrations in two locations. The system consists of two remote catalytic sensing assemblies and a solid-state controller. The controller automatically displays the higher reading channel on a digital display, scaled from 0-100% LEL (lower explosive limit). Manual override switching permits readout of the low channel at any time.

The DC110 is an eight-channel Readout / Relay Module designed to be used with up to eight of our remotely located Combustible Intelligent Sensors. The front panel contains a digital display that indicates 0-99% LEL (lower explosive limit) of the combustible gas being monitored by the Intelligent Sensors.
