Product Description
- The ISE20A digital pressure sensor from SMC is used in pneumatic systems to monitor and analyse pressure readings.
- It is suitable for use in mechanical and plant engineering, as well as for automation applications involving compressed air systems.
- The pressure sensor is used to control and monitor processes via switching signals.
- It is used wherever pressure conditions need to be reliably measured and displayed.
- The SMC ISE20A digital pressure sensor is a high-precision pressure switch for compressed air and other non-corrosive and non-flammable gases.
- The LCD display features three colours and allows several pieces of information to be shown simultaneously.
- The sensor offers a choice of NPN or PNP switching outputs, as well as various switching modes, for flexible adaptation to the application.
- Features such as digital filters, maximum/minimum value display and key lock ensure safe and convenient operation.
