Product Description

 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

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
