Overview

Ammonia in air can be measured by several methods, but only a few are practical for the food industry because of the diversity of environmental conditions.

In the food industry, each environment can be harsh with very cold temperatures, high air velocity, steam cleaning and chemical washdown, product off-gasing and widely varying relative humidity (RH) levels. Manning Systems sensors are designed to work even at 100% RH condensing conditions.

Housed in heavy gauge steel boxes, Manning Systems gas sensors are protected from even the worst of these hazards, ensuring longer sensor life and stable performance in these harsh environments.

Manning Systems latest innovation is its new family of gas sensing instruments with microprocessor-based SensorCheck™ technology. The revolutionary new SensorCheck™ technology monitors Manning Systems EC-F9-NH₃ ammonia sensor by testing it every 24 hours for electrical viability. If a sensor dries up or is disconnected, SensorCheck™ sends an indication that can be detected by a Manning Systems Gas Monitor or a PLC. For the new AirScan™ infrared family of sensors, every two seconds SensorCheck™ technology monitors the AirScan™ iR source and ensures that the dual channels are functioning properly. A notification signal will be transmitted if any of several performance parameters is not met. SensorCheck™ also monitors the incoming signal level from the source, as well as incoming voltage to ensure full signal strength.

Our broad selection of electrochemical and infrared diffusion-type sensors offers excellent choices for long-term trouble-free operation in the harsh environments of food processing and storage plants. Unlike sample draw systems, diffusion sensors monitor an entire facility continuously without concern for pump or filter maintenance, sample dilution or moisture in sample draw lines. Degradation inherent to sample draw systems is not a concern with the solid reliability of diffusion devices. This is especially apparent in facilities with continuous high moisture levels.
