| 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.
