OMEGA’s PX2300 Series high-output, low differential pressure transducers are compatible with most media, from dry air to corrosive liquids. All wetted parts are either stainless steel or elastomer seals. The electronics are housed in a NEMA 4 (IP65) enclosure. A high working pressure and high overpressure ratings ensure dependability in harsh industrial environments. These transducers are ideal for measuring pressure drop across filters and other process devices.
SPECIFICATIONS Excitation: 24 Vdc nominal Max: 30 + 0.004 x (loop resistance Ω) Vdc Min: 11 + 0.02 x (loop resistance Ω) Vdc Loop Resistance: 0 to 1000 Ω Output: 4 to 20 mA (2-wire) Accuracy: ±0.25% RSS FS at constant temperature (includes linearity, repeatability and hysteresis) Linearity: ±0.20% FS Hysteresis: 0.10% FS Repeatability: ±0.05% FS Operating Temperature Range: -18 to 80°C (0 to 176°F) Compensated Temperature Range: -1 to 65°C (30 to 149°F) Thermal Zero Effect: <±0.02% FS/°F Thermal Span Effect: <±0.02% FS/°F Sensor: Capacitive Maximum Line Pressure: 250 psig Maximum Overpressure: High Side: 1 to 5 psi = 20 x FS, 10 to 25 psi = 10 x FS, 50 psi = 5 x FS, 100 psi = 2.5 x FS Low Side: 2.5 x FS (shift recoverable) The zero will shift slightly when high differential pressure is applied. The shift may be as much as ±10% FS with overpressure applied to the low port. (Other parameters will not shift.) The shift may be recovered by a positive overpressure or if the overpressure is always in one direction, the user may apply this pressure to pre-set the sensor. Subsequent overloads of less pressure will not cause any further shift.
