notification output signal if an anomaly is identified

• Tests the sensor every 24 hours for electrical viability

• Indication can be detected by a Manning gas monitor
or PLC

Housing

• NEMA 1 #16 gauge heavy-duty steel enclosure

• Explosion-proof design available

The Manning EC-F9-NH3 with
SensorCheck™ features industry-leading
performance gas detection technology
and adds a built-in system to monitor and
predict the sensor’s electrical viability.

Available with an optional LCD that allows real time
display of gas concentration. The easy to read
display allows for quick visual error events upon
startup and troubleshooting and can be calibrated
without a voltmeter. The EC-F9-NH3 with LCD is
designed to work in the harshest environments
including chemical washdown.

General Description

The Manning EC-F9-NH3 sensor consists of a
pair of polarized electrodes isolated from the
ambient air by a gas permeable membrane. As
ammonia diffuses into the sensor, a redox reaction
occurs, generating a current linearly proportional
to ammonia gas concentration. Unlike many other
ammonia sensors, this gas diffusion detector
exhibits excellent zero and calibration stability over
long periods of time. EC cells often last 3-4 years
in the refrigerated environments of food processing
and storage warehouses. This sensor can provide
direct input into PLC’s and computer control
systems that accept a linear 4/20 mA signal either
directly from the sensor or from any Manning mulit­channel stand alone alarm consoles with relay or
analog output.

Technical summary

General Specification
Use Electrochemical (diffusion) type sensor that works in conjunction with any Honeywell Analytics readout or alarm unit. Readouts

have built in visual and audible alarms, as well as relay output for ventilation fan activation, central alarm tie-in, etc. The
Manning EC-F9-NH3 can provide a linear 4/20 mA signal input into PLC’s.

Common Operation
Operation In units without the optional LCD module, a group of LED’s are installed to the PCB. In units with the optional LCD, two external

push buttons, “Accept” and “Scroll” are used to navigate test functions and operating modes.

LCD display (optional) 2 line by 8 alpha numeric characters and continuous backlight
Output Isolated 4/20 mA, 700 ohms max. at 24 VDC. Signal output reduces to 0.5 mA to indicate a fault condition. RS-485, Modbus

RTU protocol

Accuracy +/- 5% generally, but limited by available calibration gas accuracy. Enclosure contains no moving parts, contributing to accu

Common Module
Communication 4/20 mA output: #18/3 shielded cable (Belden 8770 or equal), cable runs < 1,500 ft. RS-485: for communication cable, use

24 AWG twisted pair, shielded (Belden #9841 or equal), cable runs up to 2,000 ft. For power cable use 14 AWG (Belden
#5100UE or equal), cable runs up to 1,000 feet.

Power Source 24 VDC, 0.5 amp max.
Repeatability +/- 2% full scale

Sensor Viability Test SensorCheck, an internal microprocessor determines the sensor’s electrical viability every 24 hours. If the viability test fails, an

0.5 mA signal will idicate a fault. An internal light will show if a sensor is dried up or disconnected.

Enclosure NEMA 1, gasketed, #16 gauge steel (standard). Stainless steel or explosion-proof designs, including modified enclosures for

low temperatures, ventilation ducts, etc. are available.

Weight 3 lbs.
