A reliable sensor provides a user-friendly semiconductor sensing device and transducer which accurately detects the characteristics of a fluid, such as pressure and strain, at high temperature operating conditions. The high performance sensor is particularly useful for use with diesel engines and internal combustion engines in vehicles. The sensor can comprise a single die with a transverse strain gauge or a group of strain gauges which are located at a position on the die to help minimize electric effects of thermal stress on the gauges during pressure detection and operation of the vehicle. The die can be glass fused, such as by glass frit, to a diaphragm, such as a stainless steel diaphragm, so as not to readily corrode in the fluid.
