ST Series Submersible Pressure Transmitter
0-1 through 0-1,000 psi
High Stability Depth/Triple Seal Level Transmitter
Shallow or Deep Well Measurement
Designed for low cost of ownership
Dylix’s ST Series Submersible Pressure Transmitter is designed for low cost of ownership for level /depth measurement applications in shallow or deep wells. Key features of the ST is 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.
Manufactured for extended life cycles
Every ST Series is built using advanced manufacturing techniques to ensure the integrity of the waterproof seal. Triple sealing techniques are used and 100 % of all ST Series are submerged at our factory for at least 24 hours. Automated welding procedures and extreme environmental burn in, along with the internal protection against the harsh well conditions give Dylix’s customers the confidence of product reliability over time.
Low power / alternate materials available
From 0-5ft H2O through 0-1500ft H2O, the ST Series 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 further enhance battery life, warm-up time is less than 3 mS. Other options include alternate materials of construction or Tefzel© cable.
