FST500-200 Electronic Pressure Switch--   Electri air compressor pressure regulator switch


 Product introduction


The pressure core of FST500-200 adopts the advanced Mircofused Silicon Strain Gauge technology. Through precise digital temperature compensation, exquisite all-stainless-steel seal welded and perfect assemble technique, pressure signals are changed into electrical signals. The collective signal values are linearity corrected and temperature compensated. Control output is calculated by the the preset switching control point. The product is featured with high accuracy, high frequency response, strong resistance against interference, impact, overload, moisture-proof and good longterm stability, etc. It can be used in the pressure detection and monitor in industrial process.
