April 16, 2018 — First Sensor presents its piezoresistive pressure sensors of the HTD series with measuring ranges from 1 mbar to 7 bar. The flat sensors with a footprint of 8 x 13 mm and a height of <7 mm are designed for manifold assemblies. The HTD differential pressure sensors feature digital signal processing with 15 bit resolution and an SPI interface as well as an analog output signal.
The sensors with 3.3 V or 5 V supply are suitable for battery-powered applications in mobile and portable devices. In manifold modules, the SMD miniature sensors allow an arrangement without the tubing of individual components. For pick-and-place machines in production, the HTD pressure 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 ... 70 °C and provide a temperature reading in addition to the pressure value.
Typical applications of the HTD sensors can be found in medical devices (ventilators, anesthesia machines, CPAP, spirometers, oxygen concentrators), HVAC (volumetric flow controllers, filter monitoring, burner control), instrumentation as well as industrial and pneumatic controls.
