PID Temperature Controllers for Electric Heaters and Industrial Automation
Looking for a PID temperature controller, industrial thermostat or digital temperature regulator? RezistenteMag.ro offers temperature controllers for electric heaters, industrial ovens, extrusion lines, injection moulding machines, heated moulds, tanks and industrial processes.
The range includes ENDA, FOTEK and CALDOR temperature control products in different sizes and configurations, with PT100 or thermocouple inputs and relay, SSR or analog outputs depending on the model.
Industrial Temperature Controllers
A temperature controller measures process temperature through a sensor and controls the heating or cooling system to maintain the required set value.
Accurate temperature control helps provide a stable industrial process and controlled operation of electric heaters, ovens, heated moulds and machinery.
Depending on the application, you can select PID control, ON/OFF control, relay output, SSR control output or analog output.
PID Temperature Controllers
PID temperature controllers are suitable for processes where temperature needs to remain stable around a defined set point.
The PID algorithm adjusts the heating command according to the difference between measured temperature and the selected temperature set point.
Typical applications include:
- electric heaters;
- industrial ovens;
- extrusion lines;
- plastic injection moulding machines;
- heated moulds;
- Hot Runner systems;
- tanks and boilers;
- packaging machinery;
- industrial production processes.
PT100 and J/K Thermocouple Temperature Controllers
Selecting the correct temperature controller also requires selecting the correct temperature sensor.
Depending on the model, available controllers can operate with PT100, J thermocouple, K thermocouple and other thermocouple types.
Some controllers allow the sensor type to be selected through configuration, while other models are designed for a specific input type.
PID Temperature Controllers with SSR Output for Electric Heaters
For frequent switching of an electric heater, a PID controller with SSR control output is a commonly used solution.
PT100 or Thermocouple → PID Controller → SSR Relay → Electric Heater
The controller measures temperature and sends a control signal to the solid state relay, while the SSR switches power to the electric heater.
SSR current rating must be selected according to the voltage, power and operating current of the electrical load.
Temperature Controllers with Relay Output
Controllers with relay outputs can be used in applications where switching frequency is relatively low.
Depending on the application, the relay output can control a small load or operate a contactor or another power switching device.
The electrical rating of the controller output and the load current must always be checked before connection.
Temperature Controllers with 4-20mA Output
For processes requiring analog control signals, temperature controllers with 4-20mA output and other analog configurations are also available.
These controllers can be integrated into industrial automation systems, power control equipment and process control applications.
ENDA, FOTEK and CALDOR Temperature Controllers
The category includes temperature control products from industrial automation manufacturers such as ENDA and FOTEK, together with CALDOR solutions for electric heating control.
Available products include compact 48x48 mm controllers, larger panel controllers, analog and digital thermostats, PID controllers and products for specialized applications.
ENDA Temperature Controllers
The ENDA range includes PID and ON/OFF temperature controllers for different industrial applications.
Depending on the model, configurations are available with PT100 or thermocouple inputs, SSR control outputs and relay outputs, as well as controllers designed for Hot Runner and refrigeration applications.
Series such as ET4420, ET4430, ET7420, ET8420, ET9420 and ET401 cover different panel sizes and automation requirements.
FOTEK Temperature Controllers
FOTEK PID temperature controllers are available for industrial applications, with relay or analog output configurations depending on the model.
They can be used for heating systems, machinery and electrical panels requiring automatic temperature regulation.
Where Are Temperature Controllers Used?
- cartridge heaters;
- band heaters;
- tubular heaters;
- industrial ovens;
- extrusion lines;
- injection moulding machines;
- heated moulds;
- Hot Runner systems;
- boilers and tanks;
- hot air systems;
- refrigeration and defrost systems;
- packaging machinery;
- HoReCa equipment;
- production lines.
How to Choose a Temperature Controller
A temperature controller should not be selected only according to its physical size or price.
Before ordering, check:
- supply voltage;
- sensor type - PT100, J, K or another type;
- temperature range;
- PID or ON/OFF control;
- relay, SSR or analog output;
- controller dimensions;
- load power and current;
- the process being controlled.
Not Sure Which Temperature Controller You Need?
If you are replacing an existing controller, send us the product code or a clear photo of its label.
For a new application, tell us the supply voltage, sensor type, operating temperature, heater power and the process you need to control.
For electric heating applications we can help you evaluate the complete system: heater + temperature sensor + PID controller + SSR relay or contactor.
