Gas Detection
Innovative Fixed Gas Detection Implemented Over Modern Wireless Networks
The growing need for environmental monitoring is fueled by the need for an industrial site to control its own emissions for safety and process related reasons, to provide accurate data to local regulation bodies. As such, Continuous Emission Monitoring is becoming a key issue for operations in every type of industry. In manufacturing, processing and control, the advent and proliferation of wireless technology has enabled greater usability of detector networks because the systems are no longer limited only to locations wired for power and signal.
Banner’s experience and reliable, robust RF wireless technology combined with Oldham’s long history of expertise in gas detection brings an enhanced
technology to environmental sectors for field monitoring and measurement.
Regularly confronted with existing customer challenges, Oldham is committed to making workplaces safer around the world with innovative and efficient customer solutions. As wireless technology expands gas detection coverage over large remote locations in a cost efficient and accessible manner, Oldham’s Integrated and Engineered Solutions (iES) team worked to develop an innovative OLCT 80 field transmitter with wireless connectivity that can be used in ATEX 1 zones.
In order to implement a proven wireless system, Oldham partnered with Banner Engineering to increase the technical functionality, performance and cost effectiveness of Oldham’s OLCT 80.
Based on the standard SureCross MultiHop product range, Banner’s embedded board devices were specially designed for the needs of industrial users to provide connectivity where traditional wired connections are not possible or are cost prohibitive.
Extremely compact in size to facilitate embedding in existing products, each module has built-in discrete and analogue I/O, as well as serial communication on a Modbus platform. The self-healing and auto- routing RF network extends the networks range with multiple signal hops, each up to 3 km (line of sight), providing an easily integrated and robust wireless solution.
Every module is identical. The operational mode is selected with DIP switches between master, repeater or slave, greatly simplifying product order and integration in the sensing device.
“The Dataradio Wireless technology very quickly convinced us because of its simplicity of implementation, its integrity, power of communication and mesh capability”, stated Sebastien Martel, an iES Project Leader.
These existing technologies came together to give customers a highly- reliable, cable-free solution with overall cost reductions attributable to less cabling and less installation time. This integrated wireless solution is a resilient technology, scalable with its growing complexity. The wireless technology is agnostic to various sensor types and is available with multiple platforms or architectures, making it easy to integrate with established sensor systems. Bidirectional communication also allows for remote alarms to be integrated into a detector network, adding visibility and safety to the network status.
Banner’s experience and reliable, robust RF wireless technology combined with Oldham’s long history of expertise in gas detection brings an enhanced technology to environmental sectors for field monitoring and measurement.
In a recent application, a major UK company recently installed NH3 gas detectors at some of its sites due to the large quantities of ammonia present in this environment. The goal of this project was to allow the customer to ensure employee safety around the plant, and limit the environmental impact of a potential gas leak. The large size of the facility meant that gas detectors must be relatively far removed from the company's control center. A wired detector network in and around the plant, where it is nearly impossible to run electrical lines,
