Würth Elektronik WSEN-PDMS differential pressure sensor

Würth Elektronik has launched the WSEN-PDMS, a differential pressure sensor for a range of operating scenarios. The sensor operates with an accuracy of ±1 mbar and a resolution of 16 bits, supports a broad voltage range from 3.0 up to 5.5 V, and is compatible both with digital I2C and SPI communication interfaces as well as an analog interface. Two different casing versions make the sensor particularly versatile: they are available with vertical straight nozzles for connection with pressure adapters and with horizontal barbed nozzles for tube connection. This flexibility makes both system integration as well as prototype development much easier to accomplish.

The pressure sensor is compatible with a range of microcontrollers and embedded systems. The sensor delivers fully calibrated differential-pressure data as well as optional temperature measurements, and operates in a temperature range from –25 to +85°C. Optionally, the transmitted measurement results can be complemented by additional CRC bits, thus enabling a robust communication.

The pressure sensor is based on the design of the time-tested WSEN-PDUS sensor; like its predecessor, the WSEN-PDMS sensor is suited for a range of applications — from heating, ventilation and air-conditioning technology, filter-status monitoring, gas-leak detection, and industrial automation, all the way to medical devices such as inhalation equipment.

Like all the sensor products supplied by Würth Elektronik, the WSEN-PDMS series is also available ex stock without any minimum order quantity. It is also possible to develop versions according to the customer’s specifications to meet special application requirements.
