Servoflo Corp. has released a series of pressure sensors for low pressure measurement ranges. With an analog or digital output, the MS4515 series is available in various calibration ranges from 0 to 2 in. H2O, and 0 to 30 in. H2O.

This ceramic-based, pcb-mount pressure sensor employs CMOS signal-conditioning circuitry to create a low-cost, high-performance sensor. The analog version, the MS4515, provides a ratiometric voltage output while the MS4515DO provides a 14-bit digital output for pressure and 11-bit output for temperature in an I2C or SPI protocol.

Both models are fully calibrated and compensated with a total error band of less than 1.0% over the compensated range. The sensor operates from a single supply of either 3.3 or 5.0 Vdc. A low-power option is available. This rugged sensor is available with single or dual side ports, top ports, or manifold mount in a gauge or differential configuration. The part’s 1/8-in. barbed pressure ports mate securely with 3/32-in. ID tubing.

Samples are available for about $32 each while pricing for ordering quantities of 1000 are $21.50 each. Detailed specifications for the MS4515 and MS4515DO are available.
