The Watlow PM4 is a high-quality, panel-mounted PID temperature controller engineered for precise temperature regulation in industrial furnaces. Its clear LED display and programmable ramp/soak capabilities make it ideal for complex heat treatment processes that require specific temperature profiles. The PM4 can store up to four ramp-and-soak profiles, each with up to 10 programmable steps—making it well-suited for applications such as heat treating, annealing, or ceramic firing. In addition to controlling heating elements, it can also operate accessory outputs like event alarms or over-temperature shutoffs.
6-Segment Heat Treatment Profile Example:An example of a program could be:
Ramp up to 1500°F at 10°F per minute
Hold (soak) at 1500°F for 45 minutes
Ramp up again to 1700°F at 2°F per minute
Hold (soak) at 1700°F for 1 hours
Turn on alarm cycle complete
Then end the profile
This heat cycle can be saved to the controller’s memory, allowing operators to repeat the process easily with just a few button presses—ensuring both consistency and ease of daily operation.
