HT Series Flush Diaphragm Pressure Sensor Transmitter For High Temperature Industry

BP93420-IIIFL Pressure Transmitter


Introduction of flush diaphragm pressure sensor:

The BP93420-III-FL pressure transmitter utilizes the HT series silicon resistive film oil-filled core as the signal measuring element. Its process connection involves the direct welding of a 316L isolation diaphragm and matching flange, ensuring precise pressure measurement. The customized heat sink is designed to adapt to high-temperature environments. Inside the stainless steel housing, the signal processing circuit converts the sensor signal into a standard output signal. Rigorous testing and aging screening of the components, semi-finished products, and finished products have been conducted to guarantee the transmitter's stable and reliable performance.

Ordering tips of flush diaphragm pressure sensor
  • 1. Ensure Compatibility: When selecting the product, please verify that the tested medium is compatible with the contact parts of the product.
  • 2. Explosion-proof Products: Note that explosion-proof products do not include digital display heads.
  • 3. Power Supply for Displays: When ordering a transmitter with an LCD or LED display head, the power supply of the transmitter should not be less than 20VDC.
  • 4. Lightning Protection: To ensure the reliable operation of the product, it is advised to install lightning protection devices on-site and ensure that the product and power supply are reliably grounded.
  • 5. Sealing Ring Selection: The rated operating temperature range of the fluorine rubber O-ring is -20°C to 250°C. If the operating temperature of the product is lower than -20°C, an EPDM O-type sealing ring should be selected.
  • 6. Cable Options: The default cable length is 1.5m, and there are three types of cable materials to choose from. Unless specified otherwise, polyethylene cable materials can be used. If a different cable material is required, please indicate it in the order form.
  • 7. Special Requirements: In case of special requirements, such as strong vibration, instantaneous impact force, strong electromagnetic or RF interference, please inform us and indicate it in the order.
