GASMAX/EC gas monitor

Monday, 07 August, 2006 | Supplied by: Parker Engineering Corporation


The GASMAX/EC single channel Toxic/Oxygen gas monitor delivers the latest in gas detection technology, reliability and ease of use. The GASMAX/EC is CSA certified for use in Div. 1 and Div. 2 Explosion Proof installations and Intrinsically Safe installations with barrier.

The highly visible display shows calibrated engineering values, bar graph data, 30-minute trend and setup information. An internal real-time clock time-stamps calibration and alarm events for later review. Front panel flashing LEDs continuously indicate alarm conditions. Operator interface is via a menu-driven magnetic keypad, allowing complete setup and calibration without hazardous area declassification.

There are no potentiometers and all adjustments are performed through the magnetic keypad interface. The GASMAX/EC maintains a record of sensor calibration to track and display an estimate of "sensor life". During each post-calibration delay, the GASMAX/EC can output a value proportional to this estimate on the 4-20mA output. Controllers such as the C1 Protector can display and communicate this data to a remote DCS or the ProtectorHMI Data Visualization & Logging Software.

Locally connected Smart Sensors enhance this capability by maintaining their own electronic record of serial number, born-on date, initial calibration values, engineering units and other data, ensuring the most accurate measurement and alarming capability available today. A PC-based USB interface module allows remote configuration and programming of Smart Sensors.
