The MS4525DO 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 digital output
pressure (14bit) and temperature (11bit) transducer designed to
meet the strictest requirements from OEM customers.
The MS4525DO is fully calibrated and temperature compensated
with a total error band (TEB) of less than 1.0% over the
compensated pressure 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, gauge,
differential, vacuum 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 not ratiometric to supply voltage.
2. The maximum deviation from a best fit straight line (BFSL) fitted to the output measured over the pressure range at 25C. Includes all
errors due to pressure non linearity, hysteresis, and non repeatability.
3. Total pressure 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 and temperature, reference Transfer Function charts below.
TEB values are valid only at the calibrated supply voltage.
4. The deviation from a best fit straight line (BFSL) fitted to the output measured over the compensated temperature range.
5. For errors beyond the compensated temperature range, see Extended Temperature Multiplier chart below.
6. Start time to data ready is the time to get valid data after POR (power on reset). The time to get subsequent valid data is then specified
by the update time specification.
7. This product can be configured for custom OEM requirements, contact factory for lower power consumption or higher accuracy.
