BP93420DIII Differential Pressure Transmitter

Introduction of differential pressure transmitter:
BP93420DIII liquid pressure 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. The transmitter features a stainless steel structural design,
making it compact and easy to install
2. It undergoes strict temperature compensation and aging
screening, ensuring stable and reliable performances
3. The electrical interface can be selected as a plug-in or direct
wiring option.
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: |
