Crouzet Pneumatic Relay
The Crouzet 81 series pneumatic relay has operating pressure ranging between 2bar and 8bar with 2-hand control. This pneumatic 2-hand control device is used with dangerous machinery and requires simultaneous use of both hands to trigger and maintain machine operation. Such a device must be located outside the danger zone so that the operator cannot enter this zone before the machine has come to a complete standstill. An output signal is only generated if both control actuating devices are actuated within 500 milliseconds.
A pneumatic 2-hand control device is composed of 2 parts :
2 manual pushbuttons which require the simultaneous use of both hands.
