Development Background
Is it possible to measure a wide angle of inclination that greatly exceeds the measurement range of ±1 degree? We have developed this system in response to such customer requests.
Conventional wide-angle measurement required the use of three displacement transducers to measure the heights of three points and then convert the angles. However, this method required three displacement transducers, space for their installation, and an object of a certain size, making it impossible to measure small objects. We have solved this problem with a product that uses the autocollimator method.
Features
1. Ultra-wide measuring range
2. High-speed measurement (10K sampling)
3. Analog (±5V) measurement data output
