MEAS MS45x5HRD Digital Pressure Sensor Modules
|Measurement Specialties is set to release to production its new MS45x5HRD high resolution, digital pressure sensor modules. These sensors are a new generation of high resolution digital pressure sensors from MEAS with SPI or I2C interface up to 20MHz. The sensor module includes a high linearity pressure sensor and an ultra low power 24-bit ADC with internal factory calibrated coefficients. It provides a precise digital 24-bit pressure and temperature value and different operation modes that allow the user to optimize for conversion speed and current consumption. A high resolution temperature output allows the implementation of a thermometer function without any additional sensor. The MS45x5HRD can be interfaced to virtually any microcontroller. The communication protocol is simple, without the need of programming internal registers in the device.
With pressure ranging from 0 - 30inH2O (MS4515HRD) and 0 to 150psi (MS4525HRD), these sensors operate within -10 - +85 degC temperature compensation and 1.8 - 3.6V supply voltage. Featuring low power operation of 1uA (standby < 0.15 uA), a +/- 1.0% TEB standard accuracy and 2nd order mathematical compensation (TCG, TCO, PNL), the MS45x5 are available in gage, absolute or differential pressure types, and top, side or manifold mount ports. The MS45x5 digital pressure sensors are excellent choices for applications such as altitude and airspeed measurements, medical instruments and leak detection where high resolution and low power are critical.
