BP93420DII Differential Pressure Transmitter
Introduction of differential pressure transmitter :
BP93420DII differential pressure transmitter uses a piezoresistive
diffused silicon sensor. When the measured medium's differential
pressure acts on the corrugated diaphragms at both ends of the
sensor, the output signal from the Wheatstone bridge on the sensor
chip exhibits a good linear relationship with the differential
pressure, enabling accurate measurement of the differential
pressure. It is suitable for various gas and liquid differential
pressure measurements in industries such as petroleum, chemical,
power, and hydrology for pipeline applications.Product Features:
1. High precision: differential pressure transmitter uses diffused
silicon sensor technology to provide high precision differential
pressure measurement results, suitable for applications with high
differential pressure requirements.
2. Wide measuring range: The differential pressure transmitter can
be adapted to a large differential pressure range and can measure
small or large differential pressure values to meet the needs of
different applications.
3. Strong corrosion resistance: Piezoresistive diffused silicon
differential pressure transmitter is made of corrosion-resistant
materials, which can adapt to the measurement of various corrosive
media and has strong corrosion resistance.
4. Strong anti-interference ability: the transmitter has good
anti-interference ability, can work stably in complex industrial
environments, and accurately measure differential pressure.
5. High temperature adaptability: Piezoresistive diffused silicon
differential pressure transmitter can adapt to high temperature
environment, has high temperature resistance performance, suitable
for high temperature media differential pressure measurement.
Fast response: The transmitter has a fast response characteristic
and can monitor and feedback differential pressure changes in real
time.
6. Easy maintenance: Piezoresistive diffused silicon differential
pressure transmitters usually have a simple construction and easy
to maintain design, reducing the cost and effort of maintenance and
maintenance.
7. Multiple output signal options: The transmitter can provide a
variety of output signal options, such as 4-20mA, 0-5V, etc., to
adapt to different control system requirements.
8. High reliability: Piezoresistive diffused silicon differential
pressure transmitters have a high degree of reliability and
stability, and can work stably for a long time, reducing
maintenance and replacement frequency.
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,
chemica,metallurgy, power generation, and hydrology
3. Pressure measurement for pipelines and furnace chambers

1. When selecting the product, please ensure that the measured
medium is compatible with the product's contacting parts.
2. To ensure reliable operation, it is recommended to install a
three-valve manifold between the measurement point and the
transmitter, ensuring a slow and uniform pressure application to
the positive and negative pressure chambers of the transmitter.
3. During installation, it is advisable to position the pressure
interfaces at both ends horizontally to minimize the impact of the
installation location on the product.
4. For special requirements such as strong vibration, instant
impact force, strong electromagnetic interference, or radio
frequency interference, please inform our company and specify these
requirements in the orderOrder Guide |
