Electro Chemical NH3 Ammonia Sensor / Transmitter

 

Model EC-NH3-0/100-N/1

 

bullet

This sensor utilizes a disposable electrochemical sensor that is easily replaced by simply unplugging the old sensor and plugging in a new one.  Estimated time it takes to change sensor is approximately 30 seconds.

bullet

The sensor has a matching pre-amplifier electronics unit that provides a linear 4/20-mA signal.

bullet

When exposed to NH3, the electrochemical cell outputs a signal that is proportional to the gas concentration.

 

Characteristics

 

bullet

Because of the electrochemical sensor's selectivity, it is excellent for low PPM trip levels, 25 to 50 PPM.

bullet

The best range to consider is the 0-100 PPM unit.

bullet

Electrochemical sensor life is normally two and a half (2) to three and a half (3) years in a cool environment, i.e., below 60F.

bullet

In hot machine room environments, the life will shorten to about one (1) year.

bullet

Even though the sensor can be exposed to high concentrations of NH3 with minimal loss of life, extremely high concentrations over hours of exposure can deplete the sensor.

bullet

As this sensor ages, it will become less sensitive.

bullet

This sensor must be tested more often than the solid-state sensor because it can "fail silently".

bullet

We recommend testing the sensor a minimum of once a month and more often if the area protected is highly critical. Consider two (2) sensors for extremely critical areas.

bullet

The electrochemical sensor exhibits very selective characteristics to NH3, food processing environments, moisture and low temperatures.  There is no better method for NH3 detection at present.

bullet

Electrochemical sensors require special modifications in the following areas:

          1. Refrigerated and high moisture areas.

          2. Low temperature, -15 F and below.

          3. Duct mounting.

 

Applications

 

bullet

This sensor is ideal for processing rooms, refrigerated rooms, blast freezers, and in rooms where gas-driven forklifts are used.

bullet

The electrochemical sensor is ideal for refrigerated rooms where fruit is stored, as the sensor does not respond to ethylene gas.

bullet

Ice cream room applications are ideal because of the sensor's ability to sense at low PPM levels, 25 to 35 PPM.

bullet

Stainless steel housings are available for wash down areas, if required.
