Heatmasters Temperature Control Technology
For more than two decades Heatmasters has been at the forefront regarding temperature control systems for metal’s heat treatment applications. Everyone in business is familiar with Heatmasters' legendary Rigel26 controller and HM20/25 temperature control program. This technology has proven to be excellent in both accuracy and ease of use. Alongside Rigel/HM25 Heatmasters is working with various PLC (programmable logic) and industrial computer based solutions for temperature controlling.
In early 2019 we developed a completely new customized temperature control solution for customer’s automated production process.
Customer’s factory-level control system and control room were equipped with other manufacturer’s process control technology and this is why customer wanted heat treatment transformers with temperature control system which integrates as smoothly as possible into their production process.
After brainstorming and preliminary design process we came into the conclusion that the most cost-effective and easiest way is to embed similar PLC which was controlling the main process into Heatmasters’ transformers. This allows customer to operate with the control interface they are familiar with and without bus converters or other add-ons.
Heatmasters is providing effective solutions to customers' tailored needs and cooperate with e.g. Siemens and Beckhoff. In the picture Beckhoff panel-PC CP6600/6700 and CX8190.
The customized temperature control program inside the Heatmasters’ transformer has PID control for each channel through a thermocouple. We also gave the customer an opportunity to use their factory-level program for heat treatment control, whereby the transformer controller is given only power instruction and channel number, and which is then implemented by the transformer controller circuit.
The factory-level program will provide the transformer controller start and stop information, setpoint or before mentioned power instruction for each channel separately. PID control status, actual power value, and temperature information are amongst the data flowing back from the transformer to the main system.
The transformer controller was also provided with so-called watch dog function, which detects the contact between the controllers in the transformers and the upper level program. If the contact fails, the transformers and heating is set to stop.
And because safety comes first, we added a possibility to link the machine into customer’s emergency stop circuit, meaning that whenever and where-ever emergency stop button is pushed it will also stop the transformers and heating.
