New Versatile Rugged Pressure Sensor Provides High Resolution Temperature Output

Compact MS5837 ideal for depth measurement systems in water-based applications

Hampton, Va. — Measurement Specialties, now part of TE Connectivity (NYSE: TEL), has released the MS5837-30BA, a low power, compact, gel filled pressure sensor with an I2C bus interface and high resolution of 2 mm for depth measurement in various rugged environments.

The high linearity pressure sensor features an ultra-low power delta sigma ADC that offers precise 24-bit pressure and temperature values, while using only 0.6 µA.  With a response time as low as 0.5 ms, the MS5837-30BA offers exceptional long term stability and high measurement performance across a wide pressure range of 0 bar to 30 bar in temperatures from -20°C to +85°C.

The anti-magnetic stainless steel cap and silicone gel protecting the internal electronics make the sensor extremely water resistant. The hermetically-sealed MS5837-30BA is ideal for adventure or multi-mode watches and can be used in other rugged outdoor devices, such as mobile water depth measurement systems, dive computers and dataloggers.

The I2C bus allows the sensor to interface with almost any microcontroller for easy configuration.  It also provides different operating modes to attain high resolution or low power consumption.

The MS5837-30BA’s simple communication protocol and internal oscillator eliminate the need for external components.  The high resolution temperature output enables the unit to be used in depth measurement systems and thermometer functions without the need for an additional sensor.

This new digital pressure sensor is based on leading MEMS technology from Measurement Specialties as well as the company’s proven experience in high volume manufacturing, and easily integrates into existing vacuum nozzle pick and place processes (tape and reel).
