Barometric pressure transducer 725F

O-ringstainless steelprocess

Model 725F pressure transducer is specially designed for hydraulic chocks of longwall mining machines for underground mining. The automatic hydraulic chocks work as the powered roof support which allows shearers to work more efficiently and safely beneath the roof. This model 725F is used to control and monitor the high pressure of the hydraulic system of chocks, so that the chocks can be positioned correctly. In mining applications, the transducers must resist both vibration and mechanical shock. To meet this requirement, the model 725F transducer has its pressure diaphragm and sensor body made from one piece of stainless steel, i.e., the sensor part of 725F-series transducers possesses mono-block structure. This structure also eliminate the O-ring being integrated inside the sensor body to seal the pressure medium. As a result, the model 725F offers not only excellent resistance to both vibration and mechanical shock, but also excellent reliability. As one of the 700F-series high pressure transducers and transmitters, the model 725F makes use of metal foil strain gauges from BCM SENSOR in order to form its Wheatstone bridge circuit. One of the advantages of using the metal foil strain gauges is that all the 700F-series possesses the lowest temperature effect, compared to all the other pressure transducers and transmitters from BCM SENSOR. Last but not least, the 725F transducer features a quick connector of M8x1 female thread, which is especially developed for a convenient and reliable process connection.
