These • Computer Peripherals internally calibrated and temperature compensated sensors were specifically • Pneumatic Controls designed to provide an accurate and stable output over a 0 °C to 70 °C • HVAC [32 °F to 158 °F] temperature range. This series is intended for use with non- corrosive, non-ionic working fluids such as air, dry gases and the like. ELECTRICAL CONNECTION Devices are available to measure absolute, differential and gage pressures from 1 psi (SCX01) up to 150 psi (SCX150). The Absolute (A in model number) devices have an internal vacuum reference and an output voltage proportional to absolute pressure. The Differential (D in model number) devices allow application of pressure to either side of the pressure-sensing diaphragm and can be used for gage or differential measurements. The SCX series devices feature an integrated circuit (IC) sensor element and laser trimmed thick film ceramic housed in a compact solvent resistant case. This package provides excellent corrosion resistance and provides isolation to external packaging stresses. The package has convenient PIN 1) TEMPERATURE OUTPUT (+) mounting holes and pressure ports for ease of use with standard plastic PIN 2) Vs PIN 3) + OUTPUT tubing for pressure connection. PIN 4) GROUND If the application requires extended temperature range operation, beyond PIN 5) - OUTPUT PIN 6) TEMPERATURE OUTPUT (-) 0 °C to 70 °C [32 °F to 158 °F], two pins which provide an output voltage proportional to temperature are available for use with external circuitry. The Note: The polarity indicated is for 100 microsecond response time makes this series an excellent choice for pressure applied to port B. (For computer peripherals and pneumatic control applications. absolute devices pressure is applied to port A and the output polarity is The output of the bridge is ratio metric to the supply voltage. Operation from reversed) any dc supply voltage up to 20 Vdc is acceptable.
