Not only is this an essential process in order to recover the product being manufactured, it is also required by the Environmental Protection Agency (EPA) to ensure that all exhaust industrial gasses are particulate (dust) free or at least comply with their extremely tight particulate emission limits. Avoids excessive wear on expensive filter bags due to unnessessary cleaning initiated by simple timer systems.įirst of all what is the definition of a Baghouse (or Filter Plant as it is referred to in Europe) - it is a generic name for Air Pollution Equipment which uses a range of filter bags/ fabric types to separate particulate (dust, ash, powders etc) from the exhausting air stream. Provides "On-Demand" control of cleaning. Provides early warning of filter clogging so that maintenance can be performed during scheduled downtime without lost production. The strain-gauge technology means accurate readings and no ports to clog.Įliminates downtime due to dust-clogged pressure sensors. The BPS-400 design features a food-grade silicone diaphragm on the "dirty" side and teflon impregnated fabric on the "clean" side. The BPS-400 sensor can be mounted on the side of the dust collector, or directly on the tube sheet if a space is available. The controller also provides a 4-20mA analog ouput for recording or additional monitoring by the plant PLC or DCS. The controller provides indicator lights to show alarm status and to show that the cleaning cycle has been initiated. The NEMA 4 controller has 2 relay contact outputs used to: 1) Activate a remote alarm device on a High dP condition, telling the operator to check the system for clogged filter bags and 2) Initiate the cleaning/backwash cycle of the system. The sensor signal is connected to the control panel through intrinsically-safe barriers. The linear output of the sensor is read by the controller. In the above diagram, the sensor is mounted on the dust collector wall. The BPS-402 controller displays the differential pressure, alarms on high differential pressure and initiates the cleaning/back-wash system. The Babbitt International model BPS-400 sensor provides a non-clogging, reliable way to sense dirty filter bags. In a plant dust collection system, reliable sensing and control is necessary for plant safety and for environmental concerns.
