MS4525DO PCB Mounted Digital Output Transducer Combination Temperature and Pressure 2 I C or SPI Protocol Differential, Gage, Absolute, Compound, & Vacuum Temperature Compensated 3.3 or 5.0 Vdc Supply Voltage Low Power Option Available (standby < 1uA) 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.
