GE General Eastern pressure transmitter PTX 300 Series - Subsea
The PTX 300 series of pressure transmitters has been developed for the offshore oil and 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 an ambient pressure rating up to 5000 psi. Originally designed for aerospace hydraulic systems, the PTX 300 series utilizes micromachined piezo resistive silicon pressure measurement technology, continually developed and proven by Druck for 30 years.
The product is packaged to suit the specific requirements of subsea hydraulic control systems.In particular, the high pressure containment rating, hydraulic transient protection and integrity of cable/electrical connections combine with the precision measuring technology to make the PTX 300 series a leader in this field.
