AGS – Adjustable Gap Sensor
AGS – Adjustable Gap Sensor
The AGS sensor represents a further development of the TDC sensor. The tip can be moved forwards and backwards in an AGS, unlike a TDC where it is statically embedded in the refiner’s stator segment.
It is thus possible to calibrate it more often and faster in order to increase the sensor’s precision. This approach reduces the refiner’s downtime and lowers the total production cost.
User-friendly usage
The AGS sensor is an integrated system that includes:
- Disc clearance sensor (TDC)
- Temperature sensor
- Vibration sensor (high frequency/TVD)
- Conductance sensor
- Stepping motor that handles the movement of the tip
The system is user-friendly and the calibration is not affected by the operator.
The service panel (the Panel PC)
The management of the system includes a Panel PC that steers the calibration process and informs the operator about the calibration steps. Thereafter, the operator gets the option to accept or reject the new calibration.
Areas of use
AGS sensors can be used for all types of refiners that currently use TDC sensors, with the exception of Double Disc refiners. The tip of the AGS sensor is identical to the tip of a TDC sensor. An AGS can be used together with an RMS, RS1 or GMS measuring system.
Exchange of tips
The tip, which wears down at the same pace as the grinding plates, is easily replaced during segment change. The system has a built-in user-friendly guide for the tip change.
