BP93420DII Differential Pressure Transmitter
Introduction of Differential Pressure Transmitter :
BP93420DII differential pressure transmitter uses a piezoresistive
diffused silicon sensor. It is the external pressure through the
stainless steel diaphragm, the internal sealed silicone oil is
transferred to the sensitive chip, the sensitive chip does not
directly contact the measured medium.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. With its high sensitivity output, good
dynamic response, high measurement accuracy, good stability, easy
to miniaturize, but easy to be affected by temperature, for more
than 1kpa can be measured is the first choice for mid-range
sensors.
Differential pressure transmitters are designed to measure the
differential pressure of many gases or liquids such as water or
oil. Although the unilateral overload resistance is very high, with
a maximum allowable static pressure of + 40bar, the smallest
standard differential pressure measurement range is already from 0
to 0. + 50 mbar.
Product Features of Differential Pressure Transmitter :
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 of Differential Pressure Transmitter :
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

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 order | Order Guide |
