RMA Radial Force Measuring Axle

Made in Germany RMA sensors are used for direct tension measurement in moving webs of paper, films, foils, textiles or metals.The bearing journal supports rolls with internal mounting. Measurement of the web tension is affected by registering at both sides the radial bearing forces on a web guiding roll.

Defined and setpoint controlled web tension ensures high product quality and is the basis for a minimum of machine down-times.

The compact RMA sensors in connection with a web guiding roll fulfill 3 functions at once:

measurement of tension in the web
bearing of the shafts and rolls
guiding and deflecting the product web

Features

Direct, radial force transfer
High spring constants for the sensor permit high rotation speed ratings for the deflector roll
Optional: Nominal forces different from standard
Optional: Advanced temperature range
Easy installation thanks to flange mounting
High precision and excellent long-term stability
Optional: Sensor housing and measuring cell made out of stainless steel, for use in humid environment
