High-precision MEMS Pressure Sensors Now Also for 3.3 V Supply

Würth Elektronik expands its program of differential pressure sensors

by gabi

The family of WSEN-PDUS differential pressure sensors from Würth Elektronik has grown: The two new models work with an operating voltage of 3.3 V and are therefore compatible with most microcontrollers that support this supply voltage. The other models in the series require 5 V. What all sensors have in common is their high robustness and accuracy of up to ±0.25 percent FSS tolerance. Another innovation: A sensor version is now also available with horizontal nozzles.

The new packaging design with horizontal-barbed nozzles enables pneumatic hoses to be connected directly to the sensor nozzles. This eliminates the need for an additional adapter and simplifies the installation process. Equipped with digital I²C and analog output interfaces, the sensors deliver fully calibrated pressure data as well as optional temperature data. Different transfer functions from ±1 mbar to +15 bar (±0.0145 PSI to +0.218 PSI) may be selected. Würth Elektronik’s robust differential pressure sensors with an operating temperature range of -25°C to +85°C can be used in a variety of applications: from HVAC technology to monitoring filter status and detecting gas leaks, through to inhalers.

All sensor components in the product range and evaluation boards are available from stock with no minimum order quantities. Würth Elektronik can also design individual application-specific sensor variants on request, with customer-specific pressure ranges.
