DESCRIPTION
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.

Designation” chart below.
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.
