A low-cost, high-performance line of pressure sensors, the new PX70 Series from OMEGA comes packaged in a transistor (TO-5) case suitable for PC board mounting. It is available in full-scale ranges from 0.3 to 100 psi and in four standard package options-no fitting, top fitting, bottom fitting and differential. For gage and absolute ranges, the PX71 can be ordered without fittings, while the PX72 has a top-mounted tube fitting (bottom is vent). The PX73, also available in gage ranges, has a bottom tube fitting (top is vent). For differential measurements, the PX74, with top and bottom tubes, can be used for uni- or bi-directional results. PX70 models are compatible with clean, dry, non-corrosive gases. Price starts at $40.* Linearity: ±0.5% FS * Repeatability: ±0.3% FS * Excitation: 5 Vdc (10 Vdc max) * Storage Temp Range: -40 to 125± (-40 to 257°F) * Compensated Temp Range: -15 to 85°C (5 to 185°F) * Zero Temp Coefficient: 0.07% FS/°C * Span Temp Coefficient: 0.05% FS/°C * Bridge Impedance: 3300 ±700 ? * Proof Pressure: Range <100 psi >3x FS; 100 psi range = 2x FS * Burst Pressure: Range <100 psi >5x FS; 100 psi range = 3x FS * Common-Mode Pressure: 50 psi * Compatible Meters: DP41-S, DP25-S (see section D)
