BP93420-IQ flush diaphragm pressure sensor transmitter adopts flat
film clamp type pressure transmitter. Based on standard pressure
transmitter, it adopts welded sealing diaphragm structure to avoid
direct contact between measuring diaphragm and pressure transmitter
sealing material. Therefore, it provides a reliable way for
pressure measurement in unusual media and special occasions. The
welding sealing isolation film device has a variety of different
process connection structures and is suitable for the measurement
of high viscosity and crystalline media. Products have been widely
used in food, health, paper and other industries
Product Features of flush diaphragm pressure sensor:
1. Wide measuring range, 50.4mm clamp pressure interface.
2. Multiple output signal options.
3. Adjustable zero and full scale.
4. High precision, multiple aseptic process connection.
Applications of flush diaphragm pressure sensor:
1. Suitable for measuring non-corrosive gases and liquids with
316L.
2. Medical, biopharmaceutical, and food hygiene industries for
sterile processing.
3. Used in the paper and chemical industries, as well as for sewage
level and beverage can pressure measurements Suitable for hydraulic
and pneumatic control systems.

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 -20ºC to 250ºC. When the product's operating temperature is
below -20ºC, it is necessary to choose an EPDM O-ring seal.
