Pressure measurement
Operating pressure ranges	PTX 1800 (mA) Any zero based FS from 0.75 to 600 mH2O gauge and 3.5 to 600 mH2O absolute. Other units may be specified, such as ftH2O, inH2O, bar, mbar, kPa, kg/cm2, psi
Overpressure	The operating FS pressure range may be exceeded by the following multiples with negligible effect on calibration: 8 x for ranges up to 1.5 mH2O 6 x for ranges above 1.5 to 3.5 mH2O 4 x for ranges above 3.5 mH2O (1400 mH2O max.)
Pressure containment	10 x for ranges up to 3.5 mH2O gauge 6 x for ranges above 3.5 mH2O gauge (1400 mH2O maximum) 200 bar for absolute ranges
Media compatibility	Fluids compatible with titanium (body), acetyl (nose cone) and polyurethane or Hytrel® 6108 (cable assembly)
Excitation voltage	PTX 1800 (mA) 9 to 30 V The minimum supply voltage (V_MIN) which must appear across the pressure transmitter terminals is 9 V and is given by the following equation: V_MIN = V_SUP - (0.02 x R_LOOP) Where V_SUP is supply voltage in Volts, and R_LOOP is total loop resistance in Ohms
Pulse power excitation	Recommended power-on time before output sample: 30 ms
Output signal	PTX 1800 4 to 20 mA, proportional for zero to FS pressure
Performance specification
Accuracy	Combined effects of non-linearity, hysteresis and repeatability: Standard: ±0.1% FS BSL maximum Option D: ±0.06% FS BSL maximum (±0.08% FS BSL max. for 1 mH2O and below)
Zero offset and span setting	PTX 1800 Maximum: ±0.04 mA
Long-term stability	±0.1% FS per annum
Operating temperature range	-20 to 60°C (-4 to 140°F)
Compensated temperature range	-2 to 30°C (28 to 86°F)
Temperature effects	±0.3% FS Temperature Error Band (TEB) for 3.5 mH2O range and above ±0.6% FS TEB for ranges below 3.5 mH2O
