Det-Tronics NTMOS IP66/IP67 H2S Gas Detector - Manual (Page 3)

APPLICATION
Detector Electronics Corporation’s (Det-Tronics ® )
NTMOS stand-alone gas detector delivers an
ideal detection solution in environments where
electrochemical sensing technologies are not suitable
and extreme temperature or humidity variations exist.
The NTMOS H
2
S Detector uses the latest
Nanotechnology (NT) to ensure the highest
performance and reliability. The sensing element
is packaged and protected in a rugged stainless
steel housing, making it suitable for installation in
hazardous locations.
The NTMOS Detector is tested to the ANSI/ISA 92.0.01,
Part I-1998, Performance Requirements for Toxic
Gas-Detection Instruments: Hydrogen Sulfide. The
standard is utilized for the protection of personnel
working in hazardous industries, such as in the on/off
shore production of oil and gas.
This recommended practice applies to all toxic gas
detection instruments that satisfy the performance
requirements in ANSI/ISA 92.0.01. It establishes user
criteria for the installation, operation, and maintenance
of toxic gas detection instruments, while meeting API
requirements 14C, RP92.0.02 and others. Refer to
Appendix A for ANSI/ISA 92.0.01 test results.
FEATURES
• Fast response to all H

S concentrations
• Linear 4-20 mA output signal corresponding to H
2
S
concentration (non-isolated)
• Performance approved to ANSI/ISA 92.0.01
• Non-intrusive calibration using the internal magnetic
reed switch on the Gas Detector Termination Box
model GDTB or FlexVu ® UD10
• Automatic fault diagnostics via current output
• Detector approved as a stand alone unit and
provides automatic calibration initiation capability
• Easily integrated with the Eagle Quantum Premier ®
(EQP) system using the Analog Input Module (AIM)
to provide display and control capabilities
• Ideal for extreme environmental conditions (onshore
and offshore applications)
• Ingress Protection level of IP66/IP67 suitable for
outdoor applications.
DESCRIPTION
The NTMOS Detector uses the latest nanotechnology
for detecting the presence of hydrogen sulfide gas.
The sensor provides improved accuracy, reliability,
and extended calibration intervals when compared to
ordinary solid state type sensors. Unlike typical metal
oxide sensors, the sensor in the NTMOS Detector will not
fall asleep during operation.
The NTMOS Detector has multiple third party related
approvals. Refer to the Appendices section for more
details.

CAUTION
Be sure to read and understand the entire
instruction manual before installing or operating
the gas detection system. This product is intended
to provide early warning of the presence of H
2
S
gas. Proper device installation, operation, and
maintenance is required to ensure safe and
effective operation. If this equipment is used
in a manner not specified in this manual, safety
protection may be impaired.
