FAQ

Q1: How does an industrial digital temperature controller work?

에이: An industrial digital temperature controller reads signals from a connected sensor (such as a thermocouple, RTD, or pressure transmitter), compares the actual process value (PV) against the target setpoint (SV), and calculates the required control output. By adjusting the output signal to heaters, valves, or coolers, it maintains stable thermal, pressure, or liquid level conditions inside processing equipment.

Q2: What do standard DIN sizes mean for temperature controllers?

에이: DIN sizes represent standardized international dimensions for industrial panel cutouts, ensuring that controllers from different manufacturers fit into standard control panels. Common sizes include:

• 1/16 DIN: 48 X 48mm (compact size for small packaging machines and ovens)

• 1/8 DIN: 48 X 96mm 또는 96 X 48mm (popular for dual-display panels requiring high visibility)

• 1/4 DIN: 96 X 96mm (large-format controllers for main process control cabinets)

Q3: Can a temperature controller be used to measure pressure, flow, and liquid levels?

에이: Yes. When paired with standard linear analog output sensors (such as 4-20mA, 0-5V, or 0-10V transmitters), a multi-input digital controller can measure, display, and regulate parameters like pressure, flow rate, liquid level, and humidity, operating as a multi-purpose process controller.

Q4: Why is Electromagnetic Compatibility (EMC) important in a digital process controller?

에이: Industrial environments contain high electrical noise generated by frequency converters, motors, inductive heaters, and heavy relays. A high EMC rating prevents the digital instrument from experiencing false sensor readings, display flickering, microprocessor lockups, or signal drift caused by nearby electromagnetic interference.

Q5: What are the main differences between ON/OFF control and PID control modes?

에이:

• ON/OFF Control: Operates like a simple thermostat by turning the output fully ON when below setpoint and fully OFF when above it, causing temperature oscillation and overshoot.

• PID Control (Proportional-Integral-Derivative): Uses continuous mathematical algorithms to calculate exact power output, holding parameters at tight tolerances without overshoot, which is critical for chemical processing, rubber molding, and heat treatment.

Q6: Which sensors are compatible with digital process controllers?

에이: Multi-input controllers support a wide range of standard industrial sensors:

• Thermocouples: Types K, J, T, E, R, S, B (ideal for high-temperature ovens and furnaces)

• RTDs: Pt100, Cu50 (ideal for high-precision, low-to-medium temperature applications)

• Analog Transmitters: 4-20mA, 0-5V, 0-10V (for pressure, flow, and level sensors)

Q7: What types of alarm outputs do industrial controllers provide?

에이: Controllers use relay alarm outputs to trigger warning lights, buzzers, or safety interlocks. Common alarm options include:

• High/Low Limit Alarms: Triggers when the process value exceeds maximum or minimum safe limits.

• Deviation Alarms: Triggers when the process strays a specific amount away from the setpoint.

• Sensor Break Alarms: Alerts operators immediately if an input thermocouple or RTD wire snaps or disconnects.

Q8: How do I choose between Relay, SSR Drive, and Analog (4-20mA) control outputs?

에이: Selection depends on your switching frequency and actuator type:

• Relay Output: Best for low-frequency switching, driving solenoids, or controlling contactors on slow thermal systems.

• SSR Drive Output: Best for high-frequency solid-state relay switching, providing fast, silent, spark-free PID heating control.

• Analog Output (4-20mA / 0-10V): Best for modulating control valves, motorized dampers, or SCR power regulators requiring continuous stepless power adjustments.
