Backpressure Monitors

The exhaust backpressure caused by a diesel particulate filter depends on how much soot is trapped within it. If the backpressure gets too high, engine efficiency can suffer and in some cases the engine can even get damaged. Installing an exhaust backpressure monitor is a way of heading off this problem.

The electronic monitor collects data about exhaust pressure and temperature, and if either of these exceed certain thresholds, can trigger a red light, a buzzer or a text message. The data is also stored and can be downloaded to a laptop and analysed by an engineer. As a result, improvements to the filter system or the way it is used and maintained may be identified.

Some backpressure monitors come with displays like mini-dashboards, but we prefer to install one which conveys only essential information, which can usually be done with just two LEDs.
