ĐO LƯỜNG NHỮNG GÌ QUAN TRỌNG: TỐC ĐỘ BỀ MẶT

Cảm biến TrueSpeed là cách nhanh nhất để kiểm tra tốc độ bề mặt thực tế của các trục lăn và quần áo máy – giúp bạn dễ dàng xác định sự khác biệt về tốc độ do lỗi nhập liệu và trục lăn truyền động bị trượt.

Why relying on the Drive Control System
is a bad idea

Every piece of Paper Machine Clothing must run at precisely controlled speeds. But controlling those individual speeds comes from the drive control system making a calculated guess: multiplying the roll diameter and the thickness of the felt or fabric with π and the revs of the drive: v(fabric) = π * 2 * R2 * N

Manually inputting data puts you at risk of all sorts of errors, from typos and incorrect data to forgetting to update the data after changing the fabric. Combine this with the fact slipping drive rolls often go undetected—while the drive control system shows all section speeds are correct—and you’re left facing numerous breaks, unusual draws, sheet surface defects, or worn-out machine clothing.

Measure within a minute: no more guesswork

The TrueSpeed Sensor is the fastest way to check the actual surface speed of your rolls and machine clothing—helping you easily identify speed differences caused by input errors and slipping drive rolls.

The sensor is ready for use in just a few seconds, and the measurement itself will take about the same.

The TrueSpeed can be used on almost any position, whether wet or dry, hot or cold, stable or vibrating.
