Threaded Mount Pressure Transducer

MP56 and MP562

Introduction

Piezo-Metrics' Models MP56 and MP562 are miniature low-cost, general use transducers. These transducers are made of corrosive-resistant Titanium (6AL4V). They utilize high-reliability bulk type semiconductor strain gages bonded directly to the inside surface of the machined diaphragm.

Pressure on the diaphragm is applied through the hole in the nose which is then converted to an electric signal proportional to the pressure.
