TPH505 and TPH506 Series Micro type pressure transmitter, nominal external diameter 5mm, is specifically designed for the application associated to hydrodynamic research.

The pressure sensing element of the TPH505 Series adopt the current sophisticated MEMS (Micro-electromechanical Systems) technology, three-dimension integration, double-side processing for sensing element, etc., that keep high accuracy of the linearity. The technology of photolithography adopted on the Wheatstone strain bridge minimize the temperature drift. Based on the finite element analysis by CAD auxiliary, the designs including mechanical construction and layout position are optimized that solve the contradiction between linearity and output sensitivity under lower measuring range. Down to Φ2mm radial scaled microchip, the measuring range could reach 20kPa while keeping the stable linearity.

Tested by Shock tube, the inherent frequency of the lower measuring sensor is between 60~138 kHz. It has 0~20 kHz utilized bandwidth (Risetime<2us).
