Abstract

PURPOSE:To easily apply a precise working pressure by providing control means for comparing a load reference signal with a signal based on a detection signal detected by load detecting means and controlling constant an output from pressure applying means according to the result of comparison. CONSTITUTION:A comparator 4 compares a set value 17 of a control load with an output from a polarity inverter 13 based on a load detection signal measured by a load cell 9. A deviation signal 18 from the comparator 4 is input to a controller 5. The controller 5 decides a control characteristic of a closed loop circuit and outputs a signal as a set voltage of an electropneumatic converter 6. An output from the electropneumatic converter 6 is input to a directional selector valve 7. A pneumatic pressure selected by the directional selector valve 7 is applied to a cylinder 8. Thus, a working pressure to be applied to a work is automatically set.
