Piezoresistive Pressure Sensors Measure 1 mbar to 7 bar

First Sensor’s HTD series piezoresistive low differential pressure sensors sport measuring ranges from 1 mbar to 7 bar. They measure 8 mm x 13 mm with a height of less than 7 mm, just the ticket for space-saving manifold assemblies. The differential pressure sensors feature digital signal processing with 15-bit resolution and an SPI interface as well as an analog output signal.

 

Operating from a 3.3V or 5V supply, they are suitable for battery-powered applications in mobile and portable devices. In manifold modules, the SMD miniature sensors allow a compact arrangement without the elaborate and error-prone tubing of individual components. For pick-and-place machines in high-volume production, the sensors can optionally be supplied on tape and reel. Additional output signals such as I²C bus, 1-wire, alarm outputs or pulse width modulation are available on request. The sensors are temperature compensated from 0°C to +70°C and provide a temperature reading in addition to the pressure value. For more details, checkout the HTD series datasheet.
