Product Details
Wnk81ma diffused silicon pressure sensor transducer for water
treatment system
Product Discription
WNK81mA Pressure sensor is mainly used in water supply pipeline,
gas supply pipeline measurement, hydraulic system measurement, such
as booster cylinder, supercharger, gas-liquid booster cylinder,
gas-liquid supercharger, pressure machine, compressor, air
conditioning and refrigeration equipment and other fields.
Pressure sensor is mainly used to complete the closed-loop control
of force in hydraulic system. When the control spool suddenly
moves, in a very short time will form several times the system
operating pressure peak pressure. In typical walking machinery and
industrial hydraulics, any pressure sensor can be quickly destroyed
if such extreme conditions are not considered in the design.It is
necessary to use impact resistant pressure sensor. There are two
main methods for pressure sensor to achieve impact resistance. One
is strain exchange type chip, the other is external coils.In
addition, there is another reason that the pressure sensor is also
subjected to continuous pressure pulsation from the hydraulic pump.
