・Because an evaporation type semiconductor strain gauge is used for the sensor, durability and stability is assured.
・Because stainless steel-based material is used for the wetted parts with all-welded structure, corrosion　resistance is assured.
・Two sensors are attached to the pressure receiving part and humidity resistance is taken into consideration by　charging inert gas to the back pressure side.
・With electric dumping function and built-in linearization compensation circuit, the performance of transmitter is　improved. Electric wave hindrance countermeasure is provided, expelling the effect of transceivers, etc.
