STD Series Small Bore Submersible

0-1 through 0-3,000 psi

High Accuracy / Stability Pressure Transmitter

Designed for low cost of ownership

Dylix’s STD Series Submersible Pressure Transmitter is designed for low cost of ownership for small bore level /depth measurement applications in shallow or deep wells. Key features of the STD are its long term stability, internal protection from lightning via dual gas discharge tubes, internal EMI/RFI filtering, triple sealed cable exit and a maintenance free vent filter.

Manufactured for extended life cycle

Every STD Series is built using advanced manufacturing techniques to ensure the integrity of the waterproof seal. Triple sealing techniques are used and 100 % of all STD 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 0-10 psi to 0–3,000 psi, the ST Series is available in 4-20 mA output signal. To further enhance battery life, warm-up time is less than 3 mS. Other options include alternate materials of construction or Tefzel© cable.
