Net Safety ECO-SENSE Loop Powered Gas Detector detector (formerly branded Net Safety) is an innovative H2S gas detection package designed specifically for 2-wire, loop-powered installations. An economic and ecological choice, this extremely versatile detector functions at less than 0.75 watts of power with 10–30 V dc and a full LCD display with LED indicators.

This advanced sensor interface includes a real time clock and calendar which is used for logging events such as sensor replacement, alarms and calibrations. Calibration offset and gain factors may be viewed for accurately predicting sensor "end of life" conditions.

Operator interface is through a menu driven magnetic keypad allowing full access without opening the enclosure. There are no potentiometers and all adjustments are performed through the keypad. Calibration magnet is included for non-intrusive calibration, no other special electronic devices are needed. Users can also program warm up and calibration exit delays to avoid false alarms. Delay hold outputs at zero until sensor signals stabilize. IN/OUT alarm trip delays may also be programmed.

The ECO-SENSE H2S sensor overcomes noise immunity problems associated with electrochemical sensors by enclosing all low level signals within a grounded sensor head available in aluminum and stainless steel. An integral "transient voltage suppressor" protects the device in case of lightning or other surge voltage levels. The sensor is enclosed in a rugged Class 1, Div 1 enclosure suitable for hazardous environment installations and has been certified by CSA, ANSI and ATEX.
