SENS SG-А1 (SENS) Gas Detector
Application
Designed for continuous automatic measurement of the under-explosive concentration of combustible gases and vapors, including vapors of petroleum products in surrounding common air.
Applied within modern systems for gas content control at sites of civil engineering, chemical and petrochemical industries, machine engineering and shipbuilding industries.
Main operation sites: LNG and petroleum terminals, gas processing facilities, gas storage facilities, oil refineries, gas distribution stations, gas-filling station, car gas filling container stations, etc.
Features
- optical sensor resistant to high concentrations and exposure to corrosive and toxic substances
- continuous self-testing
- transit connection
- easy operation and commissioning
Description
Made within housing of aluminum alloy AK7ch (AL9) with oxide fluoride electroconductive coating and powder-paint coating. The housing has inspection window, two cable glands, exterior and internal grounding clamps. Clamps for connection and electronic unit are placed within. Optical gas sensor in installed within housing made of stainless steel in the lower part of the device enclosure.
Signal of optical gas sensor, with operational principle based on infrared absorption, is converted into LEL value which is made available via digital or analog interface.
Signal relays are triggered when set concentration thresholds are exceeded, failure or other events happen.
Red light indicator signals on exceeding of threshold value of LEL. Green light indicator serves for power availability indication. Yellow indicator glows in case of failure, exceeding of maximal acceptable value of LEL, unstable or poor power supply.
Configuration, calibration and verification of device is made using software “Configuration of sensors and secondary devices software”, electronic control unit and signaling device MS-K-500-3 (SENS).
