ECO-SENSE Electrochemical H2S
2-wire, Loop-powered Gas Detector
The Net Safety Monitoring ECO-SENSE detector
is an innovative H
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.
Low power gas sensor functions in a 2-wire
4–20 mA sink mode
Allows "one man" sensor calibration in hazardous
areas without area declassification. No electric
devices needed
LCD readout and front panel alarm LED indicators
for Alarm 1, Alarm 2, Fault, and IN CAL are standard
Security mode allows locking of critical parameter
CSA/ANSI/ATEX certifications
Standard "Fault Supervision" circuitry continuously
monitors for failed sensor

ECO-SENSE H2S
Features and Benefits
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 nonintrusive 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 Net Safety ECO-SENSE H
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 certied by CSA, ANSI and ATEX.
