The MS4525 is a small, ceramic based, PCB mounted
pressure transducer from TE Connectivity. The transducer is
built using our 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 5.0VDC 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.

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

Description
Output is proportional to the difference between 0psiA (P min) and pressure applied
to Port 1.
Output is proportional to the difference between Port 1 and Port 2. Output swings
positive when Port 1> Port 2. Output is 50% of supply voltage when Port 1=Port 2.
Output is proportional to the difference between 0psiG (P min) and Port 1. Output
swings positive when Port 1> Port 2.
Output is proportional to the difference between -15psiG pressure (Pmin) and
pressure applied to Port 1.
Output is inversely proportional to the difference between -15psiG (Pmin) and
pressure applied to Port 1.
Prange is equal to the maximum full scale pressure specified in the ordering information.
