Compensated Pressure Sensor from Servoflo
July 24, 2011
The MS4515 Series ceramic-based PCB-mount pressure sensor from Servoflo Corp., Lexington, MA, is available in various calibration ranges between 0–2 in.H2O up to 0–30 in.H2O and with analog or digital outputs. The analog version provides a ratiometric voltage output while the MS4515DO provides a 14-bit digital output for pressure and an 11-bit output for temperature in an I2C or SPI protocol. Both models are fully calibrated and compensated with a total error band of <1.0% over the compensated range. Supply voltage is 3.3 or 5.0 VDC; a low-power option is available. Applications include blocked filter detection, altitude and airspeed measurements, medical equipment, and fire suppression systems.
