Cast Aluminum Housing & LCD Differential Pressure Sensor For Gas
And Liquid
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.
Differential pressure transmitters can be used for reaction and
process monitoring in a range of industrial sectors, with high
resistance to corrosive media and atmospheric moisture. The
diaphragms are typically fabricated from stainless-steel and are
inherently resistant to oxidization and gas adsorption in flue
pipework for example. Inconel diaphragms can be applied for
improved resistance to salt water in marine hydrocarbon
exploration.
Product Features:
1.Stainless steel structural design, making it compact and easy to
install
2. It undergoes strict temperature compensation and aging
screening,
3. Ensuring Stable and reliable performances
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. When selecting the product, please ensure that the medium to be
measured is compatible with the contact parts of the product.
2. When placing an order, please note that explosion-proof type
products do not include digital display heads.
3. When ordering transmitters with an LCD or LED display head, the
power supply for the transmitter should not be lower than 20VDC.
4. To ensure reliable operation of the product, it is recommended
that users install lightning protection devices on-site and ensure
that the product and power supply are reliably grounded.
5. The rated working temperature range of the Fluoro rubber O-ring
is -20℃ to 250℃. When the product's operating temperature is below
-20℃, it is necessary to choose an EPDM O-ring seal.
6. The default cable length is 1.5m, available in three materials.
If not specified, it will be supplied with polyethylene cable
material. If you require a different cable material, please specify
it in the order.
7. For special requirements such as strong vibration, instantaneous
impact force, strong electromagnetic or radio frequency
interference, please inform our company and specify them in the
order
