S201 / S201 Ex Dust Monitor

Sintrol S201 Dust Monitor is used to identify bag leaks, deterioration of filters and as a broken bag detector. Continuous monitoring with two independent relays which can be manually adjusted gives flexibility to plant operators to configure the monitor to their needs. Status LED’s with three different colours visualize the performance of filtration system to anybody moving on the factory floor.

Working principle

When solid particles come in contact or close to an insulated probe they produce a charge to the probe. This phenomenon is then amplified and converted into a proportional signal to the dust concentration. The amplification consists of two signals: DC component occurs when particles come into contact of the sensor (traditional triboelectric signal) and AC signal is generated by particles coming into contact as well as passing nearby the probe. Through advanced algorithms and signal filtration Inductive Electrification provides a very accurate dust measurements output.

Benefits

Dust Monitors that withstand and lasts with low operating and maintenance costs.
Safe time, only single opening into duct/stack and no alignment needed
Easy start-up can commissioning. Once mechanical and electrical installations are performed in takes only 500 seconds (app. 8 minutes) to commission the dust monitor
Detect changes in dust level from low concentration to high amounts with confidence
Linear response – know your dust level all the time all the way
