Partlow Mechanical Controllers

The Partlow controllers are widely used in industrial process and automation industries. Partlow produces self operating, indicating mechanical temperature controllers that require no operating power. These are used for heating, cooling or heat-cool operations, and are on-off controllers, available with one or two switches. The proportional units are used to provide time proportioning outputs with position proportioning motors, pneumatic devices etc. Some controllers have dual set points for alarming or auxiliary heating.

The mechanical, non-indicating, temperature controllers are self-operating, on-off controllers for use in a wide variety of applications. They provide simple control and require no operating power.
