Mounting & Compatibility Features

• Standard mounting position: Under the mill screw, can be installed as an integrated unit with thrust bearings and pressure plates; no machining required on the mill stand surface, resulting in low installation cost and easy maintenance.
• Mounting requirements: Ensure all forces act through the sensor; measuring point as close to the roll gap (force source) as possible; minimize bending, lateral and torsional loads on the sensor.
• Compatible control unit: Millmate Controller 400 (PFVA 401), requiring dedicated matching unit PFVO 142/143 (one per sensor, can be installed up to 25 m from the sensor).
• Cabling recommendation: Prefer connectorized cables over fixed cables for improved installation flexibility and maintainability.
