BPHT24 Pressure Transmitter
Introduction of flush diaphragm pressure sensor :
BPHT24 flush diaphragm pressure sensor transmitter with threaded
flat film is a commonly used sensor in industrial automation
control systems. It can convert pressure signals into standard
electrical signals. Its threaded design makes installation very
convenient, while the flat film structure provides more stable
measurement results. In addition, this sensor also has high
accuracy, high reliability, and other characteristics, and is
widely used in various pressure measurement applications.
Product Features of flush diaphragm pressure sensor:
1. Various pressure interface options
2. Designed for hygienic applications to prevent medium scaling
3. High accuracy with a fully stainless steel structure
4. Easy to clean
Applications of flush diaphragm pressure sensor:
1. Suitable for measuring non-corrosive gases and liquids with
316L.
2. Ideal for environmental protection and chemical industries.
3. Used in the marine and aviation industries.
4. Well-suited for use in the medical, biopharmaceutical, and food
hygiene industries.

- Please ensure that the tested medium is compatible with the
product's contact part before making a selection.
- Note that explosion-proof products do not come with digital display
heads when placing an order.
- When ordering a transmitter with an LCD or LED display head, ensure
that the power supply is not less than 20VDC.
- For reliable operation, it is recommended to install lightning
protection devices in the field and ensure proper grounding of the
product and power supply.
- The rated operating temperature range of the fluorine rubber O-ring
is -20℃ to 250℃. If the operating temperature is below -20℃, please
choose an EPDM O-ring.
- The default cable length is 1.5m, and there are three cable
materials to choose from. If no special instructions are given,
polyethylene cable material will be used. If you require a
different cable material, please specify it in the order.
- If there are special requirements such as strong vibration,
instantaneous impact force, or strong electromagnetic or RF
interference, please inform us and indicate it in the order.
