Description
Micron ECO-TEMP Digital Temperature Controller – Single Set Point
The Micron ECO-TEMP Digital Temperature Controller is a compact, economical, and reliable temperature control instrument designed for industrial and commercial applications requiring accurate single set-point temperature control. It provides digital temperature indication and automatic control in one convenient panel-mounted instrument, making it suitable for machines and processes where maintaining a consistent temperature is essential.
The ECO-TEMP supports Pt100 RTD, J-Type Thermocouple, and K-Type Thermocouple inputs, allowing users to select the appropriate sensor according to their application. It features a large 3½-digit display with ±1999 indication capability and a 0.56-inch (14 mm) red LED display, providing clear visibility of the measured temperature.
Designed with simplicity and practical functionality in mind, the controller offers ON-OFF and Time Proportional control action. Its output is provided through a 1 C/O relay rated at 5 A, making it suitable for controlling heaters, contactors, relays, solenoid valves, and other compatible process equipment.
The Micron ECO-TEMP is available in two standard panel sizes: 96 × 96 × 90 mm and 72 × 72 × 110 mm. These configurations make the controller suitable for different control panel designs, machinery, and OEM applications.
Single Set Point Temperature Control
The ECO-TEMP is designed around a straightforward single set-point temperature control concept.
The operator sets the desired process temperature, and the controller continuously compares the measured temperature with the programmed set point. Depending on the selected control mode, the output switches or operates proportionally to maintain the required process temperature.
This makes the controller particularly useful for applications where one primary temperature needs to be maintained consistently.
Typical examples include:
- Heating chambers
- Industrial ovens
- Dryers
- Small furnaces
- Packaging machines
- Plastic processing equipment
- Food processing machinery
- Laboratory equipment
- Water heating systems
- Process heating equipment
Compatible With Pt100, J and K Thermocouples
One of the key features of the ECO-TEMP is its compatibility with commonly used industrial temperature sensors.
Pt100 RTD
Pt100 sensors are widely used where stable and accurate temperature measurement is required. The ECO-TEMP provides an accuracy specification of approximately 0.2% ± least count for Pt100 input.
Pt100 is commonly used in:
- Process machinery
- Food processing
- Pharmaceutical equipment
- Laboratory systems
- Heating systems
- Industrial automation
J-Type Thermocouple
J-Type thermocouples are suitable for many general-purpose industrial temperature applications. They can be used with heating equipment, machinery, ovens, and process systems.
K-Type Thermocouple
K-Type thermocouples are widely used for industrial temperature monitoring, particularly in ovens, furnaces, heaters, and thermal processing equipment.
The required input type should be confirmed when ordering the controller.
Large 3½-Digit Digital Display
The ECO-TEMP uses a 3½-digit digital display with ±1999 indication capability.
The 0.56-inch (14 mm) red LED display provides clear visibility of the measured temperature, making it convenient for operators to monitor the process from the front of a control panel.
Display advantages include:
- Large numerical characters
- Bright red LED indication
- Easy temperature monitoring
- Clear digital readout
- Reduced reading errors
- Convenient operator visibility
Digital indication also eliminates the parallax error commonly associated with analog temperature gauges.
ON-OFF Control
The ECO-TEMP can operate using ON-OFF control action, making it suitable for straightforward heating and cooling applications.
In ON-OFF operation, the controller switches the output according to the relationship between the measured temperature and the programmed set point.
The controller incorporates hysteresis, which helps prevent excessive rapid switching around the set temperature.
The hysteresis setting can be configured as fixed or variable, depending on the selected controller configuration.
Time Proportional Control
In addition to ON-OFF control, the ECO-TEMP supports Time Proportional control.
Time Proportional control can provide smoother control of the heating process by varying the proportion of ON and OFF time within a control cycle.
This can be useful in applications where closer temperature regulation is required compared with basic ON-OFF switching.
The selection between ON-OFF and Time Proportional control should be based on the characteristics of the process and the type of control equipment being operated.
Heating and Cooling Applications
The ECO-TEMP can be configured for Heat or Cool control applications.
Heating Applications
For heating applications, the controller can be used to operate:
- Electric heaters
- Heating elements
- Ovens
- Furnaces
- Heating chambers
- Drying equipment
Cooling Applications
For cooling applications, the controller can be integrated with suitable cooling equipment such as:
- Cooling systems
- Fans
- Valves
- Refrigeration-related equipment
- Cooling pumps
The selected control configuration should match the process and connected equipment.
1 C/O Relay Output
The ECO-TEMP is provided with one changeover relay output (1 C/O) rated at 5 A.
The relay can be used to control suitable external equipment directly within its rated electrical limits or to operate an external contactor or relay for higher-power loads.
Potential applications include:
- Heater switching
- Contactor control
- Fan control
- Solenoid operation
- Auxiliary equipment control
- Heating/cooling switching
When controlling high-power heaters or motors, an appropriately rated external switching device should be used.
Temperature Accuracy
The specified accuracy of the ECO-TEMP varies according to the selected input:
- J-Type Thermocouple: approximately 1%
- K-Type Thermocouple: approximately 1%
- Pt100: approximately 0.2% ± least count
Actual system accuracy can also depend on the sensor, wiring, installation, environmental conditions, and process configuration.
For critical applications, the complete measurement chain should be considered when evaluating overall temperature accuracy.
Two Panel Size Options
The Micron ECO-TEMP is available in two panel configurations:
96 × 96 × 90 mm
This larger panel format is suitable for conventional industrial control panels where a larger front-panel instrument is preferred.
72 × 72 × 110 mm
This compact format is useful where panel space is more restricted.
The appropriate size can be selected according to the control panel design and machine requirements.
