The AM75 is a digital protractor that is made to measure the bend angle of many bent tube configuration. Its measuring range is from 0 to 360 degrees in increments of 0.1 degrees. It utilizes a high-resolution encoder guaranteeing the repeatability of the bend angle measurements. The readings are displayed in huge numbers and it updates nonstop to show the real-time bend angle.
The protractor uses two arms to measure the bend angle. It includes a fixed arm and the other is the dynamic arm that has two axis of motion. The latter has both rotational and linear movement. The seal roller bearings guide the rotational motion while the linear bearing guides the linear. The motions permit the product to move fast from one bend configuration to another.
