Product Specification

MS4515DO Digital Output Pressure Sensor Specification
• PCB Mounted Digital Output Transducer
• Combination Temperature and Pressure
• Pressure Ranges from 2 to 30 inches H2O
• I2C or SPI Protocol
• Differential & Gage
• Temperature Compensated
• 3.3 or 5.0 Vdc Supply Voltage
• Low Power Option Available (standby < 1uA)

The MS4515DO is a small, ceramic based, PCB mounted pressure transducer from Measurement Specialties. The transducer is built using 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 MS4515DO 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 or differential pressure from 2 to 30 inches H 2 O. The 1/8” barbed pressure ports mate securely with 3/32” ID tubing.
