Aim\ To study the way of fast detecting the parameters about the interlock of press ′ air cushion.Methods\ The screw micrometer sensor and CMOS integrated circuit are applied for devising and developing a set of detection appliance which is related to the detection of parameters of air cushin interlock of the press.Results\ All kinds of parameters acquired through detection appliance devised by oursolves can meet the actual requirements. Conclusion\ Such set can detect all parameters of air cushion interlock of the press very quickly

which provides the reliable proof that can help examination

use and maintainance of the press.
