Main control

Product Overview

The main control detects the leak condition early when acid or base material leaks, and an alarm sounds according to the range set in the sensor. It is a device developed so that an alarm can be transmitted to a monitoring device and the damage to the sensor is installed at an early stage. It is possible to check real-time data values ​​in the field and has a data accumulation function when a sensor error occurs.


  • Changeable detection conditions for each sensor type

  • Controller setting value change function through monitor

  • Monitoring notification status and communication status

  • Alarm status and detection conditions can be changed according to the site

  • Reliability recognition through (CE) certification
