LED Digital Pressure Sensor (PISCO)｜Semiconductor switch improves detection accuracy
- To improve visibility, an LED display is adopted for the vacuum switch
- LED displays are used for set-up pressure and working pressure
- 2 points signal output type and 1point signal output with 1 analog output type is available
Selection by applications is possible. A connector wiring realize easy layout. - Output detection accuracy is enhanced by the use of semiconductor switch
- General spec.
