A miniature pressure transducer is disclosed which is able to operate at high temperatures. The pressure transducer is provided on a substrate comprising an elongate silicon base portion with one or more contact areas formed at one end and a diaphragm formed at the opposite distal end. A plurality of piezoresistive elements are provided on the diaphragm, preferably in a Wheatstone Bridge arrangement, and connected to the contact areas using interconnects. The diaphragm extends across substantially the entire effective width of the elongate base portion providing a compact width while still maintaining a sensitive pressure sensing capability.
