Ordering tips oflush diaphragm pressure sensor
  • 1. When selecting the product, please ensure that the medium to be measured is compatible with the contact parts of the product.
  • 2. When placing an order, please note that explosion-proof type products do not include digital display heads.
  • 3. When ordering transmitters with an LCD or LED display head, the power supply for the transmitter should not be lower than 20VDC.
  • 4. To ensure reliable operation of the product, it is recommended that users install lightning protection devices on-site and ensure that the product and power supply are  reliably grounded.
  • 5. The rated working temperature range of the Fluoro rubber O-ring is -20ºC to 250ºC. When the product's operating temperature is below -20ºC, it is necessary to choose an EPDM O-ring seal.
  • 6. The default cable length is 1.5m, available in three materials. If not specified, it will be supplied with polyethylene cable material. If you require a different cable material, please specify it in the order.
  • 7. For special requirements such as strong vibration, instantaneous impact force, strong electromagnetic or radio frequency interference, please inform our company and specify them in the order.
