Pneumatic Timer Applications

Pneumatic timers are used where no electrical power is available or where an application calls for "intrinsically safe" means of timing. Applications are widely varied since wherever compressed air is used, then a pneumatic timer may be included in the control logic. Examples include filling processes, dairies, vacuum pump timing, oil and gas industries, etc.

Timers can be used for maximum periods, minimum periods, operating times etc and may be short interval (300 seconds or below) or long interval (up to 100 hours).

2 seperate timers are needed when timing "on" and "off" periods. Generally a timer acts as a pilot valve to control a main valve. Always consider how to start the timer running (say by a push button) and how to reset it; how to over-ride the timing process in the event of a critical stop, and how a continuous timer cycle may be achieved.

 

The Timer & Counter Company can help you with your application, from selection of the right timer, to supply of all components to complete a timer circuit.
