PSI-4/20 - Two-Wire Pressure Transmitter pressure products Ideal Transmitter for Most Fluid and Gas Measurement PSI-4/20 offers infinite resolution. Pressure ranges are vacuum to 10,000 psi, gage or absolute, high burst pressure is 10x full scale, and overall accuracy is 0.25% F.S. (B.F.S.L.). An optional feature is adjustment capability without disassembly. PSI-4/20 consists of piezoresistive semiconductor strain gages used in a full bridge circuit. The output from the bridge circuit is conditioned by an integral electronics package that generates a 4-20 mA two wire output which is proportional to input pressure. PSI-4/20 Two-Wire Pressure Transmitter Low cost High overpressure capability Accuracy (linearity, hysteresis, repeatability): 0.25% F.S. (B.F.S.L.) Hybrid compensation circuit Zero and span adjustments 4-20 mA output CE approved PSI-Tronix Technologies Division Scientific Technologies Inc. 3950 South "K" Street, Tulare, CA 93274-7155 Operational Description R e-PSI-4/20-1 Applications Especially useful when there are great distances between the transmitter and the data acquisition system, the PSI-4/20 offers a highly accurate measurement with exceptional durability and long life. Stainless steel wetted surfaces make this unit compatible with most fluids and gases. The small size (3 oz.) makes the PSI-4/20 ideal for use where space is a concern without sacrificing high accuracy.
