The Net Safety Monitoring ECO-SENSE detector is a truly state-of-the-art H2S gas sensor/transmitter package designed specifically for 2 wire, loop-powered installations. An economic and ecological choice, this extremely low power detector functions in a 4-20mA "sink" mode at less than .75 watts with 10-30 Vdc with a full LCD display.

The advanced sensor interface allows a tiny memory chip in the sensor to provide the ECO-SENSE with parameters such as calibration, range, engineering units and important dates. A real time clock and calendar allows logging events such as sensor replacement, alarms and calibrations. Calibration offset and gain factors may be viewed and are useful for predicting sensor "end of life" conditions.

Operator interface is via a menu driven magnetic keypad allowing full access without opening the enclosure. There are no potentiometers and all adjustments are performed through the keypad. Requires only a simple calibration magnetic (included) for non-intrusive calibration, no other special electronic devices are needed.

The Net Safety ECO-SENSE H2S sensor overcomes noise immunity problems associated with electrochemical sensors by enclosing all low level signals within a grounded stainless steel sensor head. An integral "transient voltage suppressor" protects the device in case of lightning or other surge voltage levels. The ST-490 is enclosed in a rugged, NEMA Type 7 approved, stainless steel enclosure suitable for Class 1, Division 1 hazardous environment installations and has been certified by CSA, ANSI and ATEX.
