Rugged pressure sensor provides 0.5ms response time
Measurement Specialties, part of TE Connectivity, has released a low power, compact, gel filled pressure sensor with an I2C bus interface and resolution of 2mm. Designed for depth measurement in various rugged environments, the MS5837-30BA features an ultra-low power delta sigma ADC that offers precise 24-bit pressure and temperature values.
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 suitable 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. Operating from a 1.5-3.6V supply, the sensor consumes just 0.6µA (or less than 0.1µA in standby mode).
With a response time as low as 0.5ms, the MS5837-30BA offers exceptional long term stability and high measurement performance across a wide pressure range of 0 to 30bar in temperatures from -20 to +85°C. The I2C bus allows the sensor to interface with almost any MCU 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.
The digital pressure sensor easily integrates into existing vacuum nozzle pick and place processes (tape and reel). The MS5837-30BA is available now in a 3.3x3.3x2.5mm ceramic-metal package for $8.49 each in 10,000 unit quantities. Delivery time is dependent upon quantity ordered.
