Description

The PDCR 300 Aerospace Pressure Sensor has been specifically designed and and has been tested to meet the harsh requirements found within many Aerospace applications whilst also satisfying many industrial requirements. This product is founded on the highly reliable silicon chip produced within Druck’s own 21st Century clean room.

The Piezoresistive technology has been developed and enhanced for more than 45 years. Widely used within the Aerospace/Industrial and Oil & Gas markets, the compact analogue sensor provides unrivalled performance across a wide Pressure and Temperature range.

The PDCR 300 lends itself very well for a variety of uses across high pressure requirements within hydraulic systems to low pressure, barometric measurement. No micro-processors are adopted within this product, which enables reliability at high temperatures to be achieved. The conditioned millivolt output is distributed through a 4-wire configuration
