Gas and Flame Detection

Sentry Gas Detection System

The Sentry Gas Detection System is an intelligent approach to plant-wide hazardous gas detection. Multi-channel capability, extensive diagnostics, wide range of gases monitored, local display of information, serial Modbus (or other protocol) communication, Ethernet capabilities, remote alarm/display option, centralized alarm panel and proven reliability makes Sentry the trusted guardian of your facility.

Analog Gas Sensors

Gas Detection Sensors The 4-20 mA Analog Gas Sensors include detectors for combustible gas, toxic gas and oxygen deficiency with 4-20 mA output of gas concentration. Various models are available that also provide digital display, non-intrusive calibration, alarm relays and Modbus communication. Each of these models include a 4-20 mA output signal of gas concentration to interface to PLCs and other control devices.

Gas Alarm Monitors

The Gas Alarm Monitors basic go/no-go gas alarms and monitors. They include visual alarm indication and relay output and on some models audible alarms are included. These monitors are used in areas with minimal risk not requiring interface to remote locations. Gas Alarm monitors are available for combustible gas, hydrogen sulfide and carbon monoxide.

Flame Detectors

Flame Detector and Flame Detection The Flame Detectors from Sierra Monitor include Industrial flame detectors utilizing a multi-spectrum design that can detect both hydrocarbon and non-hydrocarbon based flames with the same detector. With the widest cone of vision in the industry the Sierra Monitor flame detectors can detect flames over a wider area.

In-Stream Analyzer

In-Stream Hydrogen Sulfide Analyzer The In-Stream Analyzer detects Hydrogen Sulfide in a Methane gas stream. The Model 4400 In-Stream Analyzer does not require any tapes that need a hazardous disposal permit to discard. Nor does it require the addition of hazardous chemicals for analysis.

Custom Systems

Custom Gas Detection Systems Sierra Monitor can design Custom Systems designed for a variety of industrial, commercial and military applications. Sierra Monitor's panel shop has been UL approved so we can design and construct full panel systems to meet your gas detection application needs.
