Pneumatic Timers

Pneumatic timers are used in industrial systems for the precise control of air input signals. They are used in place of electrical timers, where the use of electricity is either unavailable or unsafe, such as applications in which flammable materials are present. At RS Components, we have pneumatic timers from well-known brands of the industry, including Crouzet, Norgren, Parker and SMC.

How do pneumatic timers work?

Most pneumatic timers use a chamber and a piston to measure time, with a clock timing hand or figure wheel to measure their time cycles. However, other mechanisms can be used, including spring diaphragm and volume fill technology. Air is allowed into the chamber, which pushes the piston towards the end and allows a precise time to be set. Pneumatic timers do not use electrical current and are very accurate.

What are pneumatic timers used for?

Pneumatic timers are used where an electrical current is undesirable, restricted, unavailable or dangerous, such as in the mining, oil and gas industries. They can be used where precise time control is important. By utilising a piston and control valve rather than an electrical current found in a standard timer, such as plug-in time switches, pneumatic timers do not generate sparks that could cause fires or explosions.

Types of pneumatic timers

Choose the timer most suitable for your needs depending on maximum and minimum operating pressures, temperatures and time required. Certain models have an ATEX Hazardous Area Certification.
