Overview

Outdoor ammonia sensing is never simple, whether it is monitoring roof-top units, tank storage areas, open-sided equipment rooms or perimeter monitoring.

Regardless of the number of sensors in place or the technology used, you are always at the mercy of winds and other weather conditions. Sensors can be equipped with ATMOS technology to withstand extremes of cold and heat, plus rain, snow, etc.

Manning Systems has developed unique methods of dealing with these ever-changing conditions to protect the sensor and increase the probability of catching a leak in time for emergency response and containment of the problem. The EC-F9-NH ₃ electrochemical sensor works well for outdoor applications, is specific to ammonia to low ppm trip levels, and can be housed to withstand extreme weather conditions.

Manning Systems enclosures with optional ATMOS equipped® technology (Adaptive Temperature and Moisture Optimizing System) feature the first enviro-adaptive technology available for gas sensors. Manning Systems electrochemical and infrared gas sensors with ATMOS equipped® technology can automatically adapt to environments from -50°F to 100% humidity and washdown conditions, assuring industry leading performance in the harshest environments.

When discussing outdoor applications, please provide information about the plant location, potential gas interference from neighboring industry, proximity to roads, schools, hospitals, residential areas, distances to sensors from monitoring equipment, etc.

All Manning Systems sensors can be monitored by the GM-1 single channel gas monitor or the GM-10 or GM-4 multi-channel gas safety systems that provide an individual bargraph display of gas concentration for each channel, plus relay outputs for emergency response and ventilation control.

The new AirAlert™ 96d multi-channel gas monitoring system adds addressable RS-485 Modbus communication protocol to the broad line of Manning Systems readout/alarm units. A total of 96 gas sensors and relay modules can be linked to a single controller. The AirAlert™ 96d is an appropriate readout choice for perimeter monitoring because of its "daisy chain" wiring configuration.

The redundancy provided by a Manning Primary Safety System (MPSS) gives an extra measure of gas monitoring protection and peace of mind.

Adequate information and gas-specific technology improve the chances of catching an ammonia leak, even in difficult circumstances.
