Description
Originally designed for aerospace hydraulic systems, the PTX300 series utilizes micromachined piezo-resisitive silicon pressure measurement technology, continually developed and proven for decades. It’s 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 Druck’s PTX300 series a leader in this field.

Pressure Measurement
- Operating pressure ranges: A full scale (FS) pressure range may be specified between 0 – 228 bar and 0 – 1035 bar, sealed gauge
- Proof pressure: Proof pressure tested to 1.5 x FS pressure
- Overpressure: The operating pressure range can be exceeded by 1.5 x FS pressure to 1600 bar max, whichever is less.
- Secondary containment pressure: The transmitter will safely contain up to 1150 bar maximum without leakage of pressure media.
- External case pressure: Tested to 300 bar with negligible change in calibration.
- Pressure media: Fluids compatible with a fully welded assembly of Inconel 625 and Stainless Steel.
- Transmitter Supply Voltage: 10 to 32 VDC. The minimum supply voltage that must appear across the transmitter terminals is 10 VDC. and is calculated by: VMIN = VSUP – (0.02 x RLOOP)
- Supply sensitivity: <0.005% F.S./Volt. Insulation resistance >100M Ohm @ 500 Vdc
- Output current: 4 to 20mA (2-wire) proportional for zero to full scale pressure
Performance
- Accuracy: Combined Non-linearity, Hysteresis and Repeatability: ±0.1% F.S. B.S.L.
- Zero off set and span setting: ±1% F.S. nominal at 23°C.
- Long term stability: At standard reference conditions, any calibration change will not exceed 0.1% F.S. per annum.
- Temperature range: Process/ambient -20 to 40°C/ Compensated -20 to 40°C Storage -30 to 50°C
- Temperature effects: ±0.5% F.S. Total Error Band.
Physical
- Pressure connection: Face or Spigot with O-ring seal connection.
- Electrical connection: Flying lead 3m long with striped ends, prepared by tinning and soldering. Cable type Raychem FLHTC0311-0.35
- Weight: Approx 270 grams nominal.
- Ingress protection: IP68, submersible to 3000m H2O.
