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
DC
and requires a single external component for proper
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.

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. For details on environmental conditions and pressure type descriptions, reference to relative tables.
