CPGD10-100V Methane Sensing System

Manufacturer: Carbon Controls Ltd
Carbon Controls Ltd offers process gas sampling systems for combustible and toxic gases.

The CPGD10-100V Methane Sensing System is custom designed to continuously monitor an incoming gas sample for Methane on Natural Gas applications.

A Primary application is to replace traditional Oxygen Sensing Systems on Vacuum Screw Compressors.

Traditional Oxygen Sensing Systems employ passive sensor technology that directly measures the O2 ingression into the gas stream when operating systems are on vacuum.

Common problems with these systems revolve around the short life of the passive sensor, which causes high maintenance and replacement costs.

Passive sensor technology is also not fail safe, and therefore monitoring system failure without operator notification can occur, creating a potentially explosive situation.

The Carbon Controls CPGD10-100V system uses ActiveTechnology for the sensor, providing a fail-safe approach to the monitoring system. The sensing element is continuously exposed to 100% levels of Methane and infers Oxygen ingression when this signal drops below a specified setpoint.

Using this approach provides no requirement for sensor calibration during the service life of the system.

This system differs from all other models because it utilizes silicon based solid-state sensors. The complete optomechanical design and construction is so stable that an ultra fast speed of response can be achieved whilst providing unparalleled service life and detector stability.

This ultimately saves on maintenance and service costs.
