GAS DETECTION

Sentry IT Gas Sensor Module

IT Toxic Gas

180 Day Calibration Interval

Network enabled toxic gas detection

Information Technology (IT) at the component level!
A network enabled Gas Sensor Module with the
brilliance to provide Sentry, 4-20 mA or Modbus
output. This is a stand alone module with the
intelligence to provide integral alarms, loaded with
features you need. A gas detector with a Sierra
Monitor pedigree, Factory Mutual approved and
ready to manage your gas risk. The 5100-XX-IT
Series provides all the built-in features desired by
instrumentation and safety professionals, including:

 FM Approval for performance and safety
 180 day calibration frequency
 SIL-2 Certified
 Modbus RTU RS-485 interface
 4-20 mA output
 HART Interface
 SMC Sentry digital bus interface
 ATEX Approved (5100-05-IT)
 IECE

x Certified (5100-05-IT)

 Optional Integral alarm relays – Alarm,

Warning and Trouble

 Aluminum or 316 Stainless Steel enclosure
 Integral scrolling LED display
 Remote alarm reset
 Optional remote sensor

The 5100-XX-IT can be used as a 4-20 mA
component or as a Modbus RTU node. For higher
level system capabilities the module can interface
directly to Sierra Monitor’s Sentry Controller. As
part of a Sentry system the user gains capability of
system Modbus serial communications, extensive
diagnostic features, area and zone alarm
management, WebServer interface and multiplexing
sensor connections.

IIB+H2 IP66. The 5100-XX-IT is also SIL Certified
and meets NFPA-72 requirements for gas
detectors.

How It Works

Electrochemical sensors are fuel cell-like devices
consisting of an anode, cathode and electrolyte.
The components of the cell are selected so a
subject gas, allowed to diffuse into the cell, will
cause a chemical reaction and generate a current.
The cells are diffusion limited so the rate the gas
enters the cell is solely dependent on the gas
concentration. The current generated is proportional
to the rate of the consumption of the subject gas in
the cell.
