Flanged Flush Diaphragm Pressure Sensor DN25 Piezoresistive Pressure Transmitter

Piezoresistive Pressure Transmitter Flush Diaphragm Pressure Sensor DN25 Flanged Diaphragm Sensor

BP93420-IIIFL Pressure Transmitter


Introduction of flush diaphragm pressure sensor:

The BP93420-III-FL pressure transmitter uses the HT series silicon resistive film oil-filled core as the signal measuring element. The process connection adopts direct welding of 316L isolation diaphragm and matching flange to ensure the precision of pressure measurement. The customized heat sink can adapt to high-temperature environments. The signal processing circuit located inside the stainless steel housing converts the sensor signal into a standard output signal. The entire product has undergone rigorous testing and aging screening of components, semi-finished products, and finished products, ensuring stable and reliable performance.

Ordering tips of flush diaphragm pressure sensor
  • 1. When selecting the product, please ensure that the tested medium is compatible with the contact part of the product.
  • 2. When placing an order, please note that explosion-proof products do not include digital display heads.
  • 3. When ordering a transmitter with LCD or LED display head, the power supply of the transmitter should not be less than 20VDC.
  • 4. To ensure the reliable operation of the product, you are advised to install lightning protection devices on site and ensure that the product and power supply are reliably grounded.
  • 5. The rated operating temperature range of fluorine rubber O-ring is -20℃~ 250℃. When the operating temperature of the product is lower than -20 ° C, EPDM O-type sealing ring should be selected.
  • 6. The default cable length is 1.5m and there are three kinds of materials to choose from. If there are no special instructions, polyethylene cable materials can be used. If you need a different cable material, please specify it in the order form.
  • 7. In case of special requirements such as strong vibration, instantaneous impact force, strong electromagnetic or RF interference, please inform us and indicate in the order.​
