The Ashcroft Gauge Pressure Sensor provides precision pressure measurements in compressed air systems, water, or other compatible gases and fluids with an accuracy of ±1% FS from -20° to 85°C (-4° to 185°F) and only ±1.5% FS -40° to -20°C and 85° to 125°C (-40° to –4°F and 185° to 257°F). Requires analog port selection during U30 system or RX3000 configuration and use of a S-FS-CVIA when using the H22-001 data logger. When using a UX120-006M, ZW Series or U12 data logger, this sensor requires an 0-5 Vdc analog input cable (CABLE-ADAP5) and external power provided by an AC adapter (AC-SENS-1).
