SMP3002 Piezo-resistive welded pressure sensor
SMP3002 Piezo-resistive pressure sensor is a sensor encapsulating
the isolation film sensor core in the stainless steel shell, with
SS 316L diaphragm and stainless steel shell and interface. This
sensor has good media compatibility, reliable and stable
performance, with M20 * 1.5 external thread. The back-end interface
is M27 * 2 external thread, which is convenient for customers to
directly install and use.
The product is suitable for a variety of gas, liquid medium
pressure measurement. It can be widely used in petroleum, chemical,
marine, hydraulic systems and other industries process control and
measurement.
