PMC133 pressure transmitter

Product Features

Imported dry-type capacitive ceramic sensors and diffused silicon sensors are used. Measurement range: 2KPa~70MPa, specifically for measuring negative relative pressure,

Strong resistance to overload impact, good long-term stability and temperature characteristics, and simple direct installation method.

working principle

A flat capacitor structure is composed of 96% or 99% alumina ceramic film. The medium pressure of the sensor directly acts on the ceramic sensor

The instrument membrane causes displacement of the measuring membrane. Normal pressure causes the measuring diaphragm to shift by 0.025mm. Overpressure only causes the measuring diaphragm to shift

Offset by 0.1mm. At this point, the measuring membrane is attached to the ceramic bracket to avoid damage to the sensor. Measure the electricity generated by the displacement of the diaphragm

The capacity is detected by electronic components directly connected to it, amplified and converted into standard signal output.
