Diaphragm Pressure Transducer Definition
Diaphragm pressure transducer adopts super-large diaphragm design, core body adopts imported material, diaphragm isolation technology, test head has no pressure hole, there is no clogging of viscous medium during measurement, integrated structure design, suitable for viscous Pressure measurement and control of viscous media such as chemical coatings, paints, mud, asphalt, crude oil and other media. Such sensors are also commonly referred to as: flat film diaphragm pressure transducer, paint diaphragm pressure transducer, food diaphragm pressure transducer, flush diaphragm pressure transducer, hygienic pressure transducer, Flat membrane pressure transducer for concrete.
In some occasions, A diaphragm pressure transducer will be understand as mechanical device with pointer. it will be different with retransmission type of diaphragm pressure transducer although they have same connection solutions. you can learn it more here.
Advantages of Diaphragm Pressure transducer
Diaphragm pressure transducer, because the isolation diaphragm is in contact with the medium in a large area, so it is suitable for closed occasions; The flush mount pressure transducer especially measure of viscous or slurry medium and strong corrosive liquid, or the medium rich in particles.
Diaphragm Pressure transducer Applications
Diaphragm pressure transducer is suitable for pressure measurement and control of viscous media such as chemical coatings, paints, mud, asphalt, crude oil, etc.
