PTX 300 Series – Subsea Pressure Transmitters

The PTX 300 series of pressure transmitters have been developed for the offshore oil & gas industries as a compact, high performance device for reliable and long term subsea use. Maintenance free, it is available with operating ranges up to 22,500 psi and is fully submersible with a pressure rating up to 5000 psi. Originally designed for aerospace hydraulic systems, the PTX 300 series utilizes micro-machined piezo resistive silicon pressure measurement technology, developed and proven by Druck for 30 years.
