MS4525 SPECIFICATIONS  PCB Mounted Pressure Transducers  Amplified Ratiometric Analog Output  Differential, Gage, Absolute, Compound, & Vacuum  Temperature Compensated  3.3 or 5.0 VDC Supply Voltage The MS4525 is a small, ceramic based, PCB mounted pressure transducer from Measurement Specialties. The transducer is built using Measurement Specialties’ proprietary UltraStable™ process and the latest CMOS sensor conditioning circuitry to create a low cost, high performance transducer designed to meet the strictest requirements from OEM customers. The MS4525 is fully calibrated and temperature compensated with a total error band (TEB) of less than 1.0% over the compensated range. The sensor operates from single supply of either 3.3 or 5.0V and requires a single external component for proper DC operation. The rugged ceramic transducer is available in side port, top port, and manifold mount and can measure absolute, gage, differential, or compound pressure from 1 to 150psi. The 1/8” barbed pressure ports mate securely with 3/32” ID tubing. SENSOR SOLUTIONS ///MS4525 09/2017 Page 1

See “Wetted Material by Port Designation” chart below. Notes 1. Proper operation requires an external capacitor placed as shown in Connection Diagram. Output is ratiometric to supply voltage variations of less than 10%. 2. The maximum deviation from a best fit straight line (BFSL) fitted to the output measured over the pressure range at 25°C. Includes all errors due to pressure non linearity, hysteresis, and non repeatability. 3. Total error band includes all accuracy errors, thermal errors over the compensated temperature range, and span and offset calibration tolerances. For ideal sensor output with respect to input pressure, reference Pressure Transfer Function charts below. TEB values are valid only at the calibrated supply voltage. 4. For errors beyond the compensated temperature range, see Extended Temperature Multiplier chart below. 5. This product can be configured for custom OEM requirements, contact factory for lower power consumption or higher accuracy. 6. Long term stability over a year period with constant voltage and temperature 7. Pressure connection: barbed ports are designed for use with tubing 3/32” ID, 60-70A durometer (PVC). 8.
