It is very important to monitor the backpressure in any exhaust system fitted with a diesel particle filter, in order to give early warning in case regeneration is not occurring as intended, or of the need to remove accumulated ash. Blackthorn can supply low-cost and reliable analogue systems or more sophisticated electronic alternatives. The advantages of an electronic backpressure monitoring system are that it may be programmed to sound an alarm or even to shut down the engine in the event of backpressure exceeding a certain threshold. In systems where active regeneration of the filter is required, this is often initiated in response to signals from an electronic backpressure monitoring system.
