Overview

We are providing the following information to assist you in designing a gas detection system using Manning Systems Gas Leak Detection equipment. Selection of the appropriate sensor and enclosure is the secret of a dependable gas detection installation. Nothing can take the place of choosing the correct primary gas measurement technology. Detailed descriptions of each sensor technology characteristics and performance are found in Technology. All brochures and readout instruction manuals can be downloaded from the website.

NOTE: These drawings and specifications do not include the complete Manning Systems product offering.

Ammonia Gas Detection System

The Ammonia Gas section includes single and multi-channel readouts and a selection of sensors including the EC-F9-NH₃ electrochemical sensor for low ppm ammonia specific sensing in engine rooms and refrigerated areas, the IR-F9 infrared sensor for high level (percent range) ammonia sensing, and the VL vent line sensor to monitor refrigerant relief lines.

Food Plant (multiple gases)

The Food Plant section contains information about similar processing and storage environments, but includes ammonia and other gases that are often found in a typical food processing operation, i.e., combustibles, carbon dioxide, chlorine, etc. Manning Systems can monitor many gases in addition to those shown in the example.

Patented ATMOS equipped^® enviro-adaptive technology for gas sensors

Manning Systems electrochemical and infrared gas sensors have been engineered to accurately and reliably detect wide-ranging concentrations of toxic gases over broad ambient temperature and humidity ranges. Manning Systems offers ATMOS equipped^® (Adaptive Temperature and Moisture Optimizing System) enclosures, the first enviro-adaptive technology available for gas sensors that allows seamless performance in hostile environments ranging from outdoor applications, washdown in processing plants, freezers down to -50°F, chemical plants and specialty/military testing sites. ATMOS equipped^® enclosures actually sense the surrounding environments and create a controlled, mini-atmosphere inside the sensor that optimizes the air sample quality. ATMOS equipped^® enclosures allow Manning Systems electrochemical and infrared sensors to automatically adapt to their environment and provide accurate and reliable performance under the harshest conditions.

Diffusion Versus Sample Draw

All Manning Systems fixed design sensors operate by the diffusion method. A diffusion-type system has great advantages in cold or wet environments typical of food processing plants. These is no danger of pumping water back to a central analyzer or the possibility of diluting the ammonia sample, as would be typical of a sample draw system installed in a wet environment. Ice or water formation in the tubing can block the return lines and totally disable a sample draw system. Diffusion-type sensors that have no moving parts eliminate the need for continuous pump or filter maintenance.

Quality Construction

Because we know that effective and reliable gas detection systems can save lives, Manning Systems is committed to high-quality, durable construction, including robust, well-designed steel sensor and readout enclosures. Manning sensors are enclosed in sturdy steel boxes and can be mounted easily and have pre-punched holes to accommodate conduit and flex. The enclosures have adequate room to work inside with high quality connectors that are removable for easy wire insertion. Unlike fragile plastic housings that may break in cold temperatures and have non-secured hardware that can be lost during maintenance, Manning Systems enclosures have secured hardware and hinged doors to speed sensor installation in both cold and wet environments.
