Device overview	The Non-contact Web Tension Meter is a device equipped with the Air Turn Bar that measures the air pressure in the gap with the raised base material and converts the air pressure into the tension to carry out tension measurement and tension distribution measurement in a contactless manner. It can also carry out the detailed measurement of slack in the base material.
Special features	Non-contact measurement Fast response rate Ultra-low tension measurement Hot spot measurement Intrinsically explosion-proof construction Non-contact measurement in liquid
Use	Non-contact tension measurement for films, paper, metal foils, rubber sheets, fabrics, and other non-porous base materials Tension distribution measurement (substrate width direction)
Main Unit	Tension output：Touch panel (graphs/numbers) or panel meter (numbers) Analog output：4~20 mmA/1~5 V Measurement precision：±1%, full scale (pressure sensor accuracy) Responsivity：Within 20 ms Measurement availability：1〜1000N/m Measuring points：Any points (minimum pitch: 40.5 mm) Included angle：90~180 degrees (standard: 90, 180 degrees)
Diagram of the measurement principle	Pressure changes in the gap between the film raised by air and the surface of the turn bar are detected to display the tension.
