P431 Submersible Pressure Transmitter
Brand: Tel-Tru Manufacturing Co.Key features of the P431 are its long term stability, internal protection from lightning via dual gas discharge tubes, internal EMI/RFI filtering, double sealed cable exit and a maintenance free vent filter.
Every P431 is built using advanced manufacturing techniques to ensure the integrity of the waterproof seal.
Double sealing techniques are used and automated welding procedures and extreme environmental burn in, along with the internal protection against the harsh well conditions give customers the confidence of product reliability over time.
From 0-5 Feet H₂O through 0-1,500 Feet H₂O, the P431 is available in either a 4-20 mA or 0-5 Vdc output signal. For remote or battery powered systems, a low power option is available from a 5 Vdc, 1.5 mA supply.
To futher enhance battery life, warm-up time is less than 3 Milliseconds. Other options include alternate materials of construction or Tefzel cable.
