For the height or length measurement of patient tables linear or rotary encoder can be used. In lithotripsy applications the angle of the C-style arm can be measured by a rotary encoder or an inclinometer. With the inclinometer the installation effort can be reduced compared to an encoder by saving mounting brackets and couplings.
