Controllers & Timers

Dwyer controllers are designed to manage and regulate various process parameters such as temperature, pressure, flow, and level in industrial applications. These controllers are highly valued for their precision, reliability, and versatility, catering to a wide range of industries including HVAC, water treatment, and manufacturing.

Dwyer's temperature controllers are particularly popular, offering solutions for both simple and complex temperature control applications. They often include features like PID (Proportional, Integral, Derivative) control, which provides precise temperature regulation by continuously calculating an error value and adjusting the process control inputs accordingly. This is essential in processes where maintaining a consistent temperature is critical.
