Wireless Gas Monitoring Systems

2019-05-15   Nur Hasanah   Technology

Wireless gas monitoring technology is used to provide an early warning of the presence of toxic gas leading to enhanced personnel safety. Monitoring remote areas is typically very difficult and dangerous. It is often cost prohibitive to install and operate conventional gas detection systems at these sites. Wireless gas monitors help to solve a critical safety problem in remote applications both reliably and cost-effectively.

How it works

A wireless gas monitor uses a gas sensor module to monitor for the presence of toxic gas. The gas sensor module may consist of an electrochemical sensor inside a sensor module installed into the transmitter housing. Electrochemical gas sensors consist of a set of electrodes separated by electrolyte material. When the target gas is present inside the sensor housing, it oxidizes or reduces on the sensing electrode creating an electric signal across the cell which is interpreted by the transmitter and converted into a wireless-enabled signal.

Common Uses

Facility personnel that are unable to remotely monitor for the presence of toxic gas could enter potentially dangerous areas leading to unsafe working conditions. Wireless gas monitors increase worker safety through early gas leak detection in hard-to-reach areas. Examples of challenging, remote applications where wireless gas monitors would be useful include: areas where oil or natural gas is processed, stored, or transported; wastewater treatment facilities; and pulp and paper mills.
