BP93420DIII differential pressure transmitter
Introduction of diffrential pressure transmitter:
BP93420DIII differential pressure transmitter employs a
piezoresistive silicon sensor. As the measured medium's
differential pressure affects the corrugated diaphragms on both
ends of the sensor, the Wheatstone bridge on the sensor chip
produces an output signal that shows excellent linearity with the
differential pressure. This allows for precise measurement of the
differential pressure. The transmitter is ideal for conducting
differential pressure measurements in diverse gas and liquid
applications, particularly in industries like petroleum, chemical
for pipeline installations.
Product Features:
1.Stainless steel structural design, making it compact and easy to
install
2. It undergoes strict temperature compensation and aging
screening,
3. Diffused silicon pressure sensor is a common industrial control
and measurement instrument, widely used in gas, liquid and other
pressure measurement fields. It is basically composed of a pressure
sensor element containing a diffused silicon wafer, and the
pressure signal is converted by the piezoresistive effect shown by
the diffused silicon wafer
Applications:
1.Suitable for measuring differential pressure of various gases or
liquids in
pipelines of industries such as petroleum, chemical, power, and
hydrology.
2.Applied in industrial on-site processes such as petroleum,
chemical,
metallurgy, power generation, and hydrology
3.Pressure measurement for pipelines and furnace chambers

Ordering tips:
1, temperature compensation, diffused silicon pressure sensor is
semiconductor, semiconductor has strong temperature
characteristics, no temperature compensation, measurement error may
be relatively large.
2, the diffused silicon pressure sensor sensing diaphragm is only a
few tens of meters thick, do not touch.
3, the power supply voltage to be stable, the sensor is actually a
bridge, the power supply voltage fluctuation will cause the bridge
output changes, affecting the measurement accuracy.
4, to be used within the rated voltage, overvoltage will lead to
sensor damage.
5, the output end do not short circuit.
