Introduction of flush diaphragm pressure sensor:
BP93420 - III - FL pressure transmitter utilizes the HT series
resistance silicon membrane oil-filled core as the signal measuring
element. Its process connection encompasses the direct welding of
the 316L isolation diaphragm and the matching flange, guaranteeing
precise pressure measurement. A custom radiator is designed to
accommodate high-temperature environments. Within the stainless
steel housing, a signal processing circuit converts the sensor
signals to the standard output. Components, semi-finished products,
and finished products undergo strict testing and aging screening to
ensure that the transmitter's performance is stable and reliable.

| 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.
