How to Determine if an Electric Heater is Good or Bad Using an Ohmmeter
Both heaters and power and temperature controllers are subject to performance issues, so it is important to inspect both for signs of wear and breakdown. Here we will cover all you need to know about ohms, ohmmeters and signs that your electric heater needs to be repaired or replaced.
Retrofitting from the Watlow® SERIES F4 to the F4T®
Transitioning to a new process controller does not need to be an arduous process. Watlow® has created the new F4T® with retrofitting in mind. This means you can be back up and running in as little time as possible.
Where Should My Temperature Sensor Be Placed?
The controller can only respond to the temperature changes it “sees” through feedback from the sensor location. Therefore, sensor placement is critical to the amount of heat applied to your process.
Heat Loss Factors
Understanding the factors that influence heat loss allows you to better calculate the insulation and power needed to heat your product. By troubleshooting any inefficiencies and reducing heat loss you can make your heating system more efficient. In this article we explore the factors related to heat loss and provide graphs to assist in calculating your current or projected heat loss.
The Benefits of Cascade Control
Cascade control involves the use of two discrete control loops. Learn how cascade control can improve your process.
Rules of Good Thermocouple Practice
With proper installation and normal conditions, thermocouples can be depended upon to give trouble-free service and long life. This guide walks through the basics of proper thermocouple usage.
How to Use Watlow’s Wattage Calculator
Discover how you can use this convenient tool to size your heater and power and temperature controllers to your specific heating needs.
What is a Control Loop and How do I Set it Up?
A temperature control loop is one of the most common examples of a control loop. Control loops work to maintain the temperatures in our homes and offices. They are used for a range of immersion and industrial heating systems as well. Click the headline to continue reading.
