Precision Temperature Controller for LED Lens Molding

Product Specifications

Technical details and manufacturing context for Precision Temperature Controller

Definition

This Precision Temperature Controller is a critical component of the Precision LED Lens Molding Machine, ensuring accurate temperature control during the lens molding process. It monitors temperature sensors, processes feedback, and adjusts heating/cooling elements to maintain precise thermal conditions required for optimal material flow, curing, and dimensional stability of LED lenses. The controller uses temperature sensors (thermocouples or RTDs) to measure actual temperature, compares it with setpoint values through a PID (Proportional-Integral-Derivative) control algorithm, and outputs control signals to heating elements or cooling systems to maintain temperature within specified tolerances. Key parameters include a temperature control range of -40 to 85 °C (wider range available on request), control accuracy of ±0.05 °C at steady state, and a PT100 sensing element per IEC 60751 (Class A). Supply voltage is 24 V DC ±10% with reverse polarity protection, power consumption ≤5 W (excluding load), and output load of 10–30 A for resistive loads. Setpoint resolution is 0.1 °C, adjustable via keypad, and the display is a 4-digit LED 7-segment. Ambient operating temperature is 0–50 °C (non-condensing) with humidity ≤85% RH (non-condensing). Ingress protection is IP54–IP65 (front panel IP65) per IEC 60529, housing material is ABS (flame retardant V-0 per UL 94), and weight is 0.5–1.0 kg depending on model. The controller is designed for integration into industrial machinery; verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The controller operates by continuously reading temperature from sensors (thermocouples or RTDs). It compares the measured value to the user-set setpoint using a PID algorithm. Based on the error, it calculates appropriate output signals to drive heating or cooling elements, adjusting power to minimize deviation. The PID parameters can be tuned to match the thermal dynamics of the specific process. The controller includes safety features such as reverse polarity protection and operates within specified ambient conditions. It provides a 4-digit LED display for monitoring and keypad for setpoint adjustment. The output stage is designed for resistive loads up to 30 A, and the controller is housed in a flame-retardant ABS enclosure with IP54–IP65 protection.

Frequently Asked Questions

What is the temperature control range of this controller?

The standard temperature control range is -40 to 85 °C, with a wider range available on request. Verify the exact range for your specific model with the manufacturer.

What type of temperature sensor does it use?

It uses a PT100 sensing element per IEC 60751, Class A. This is a resistance temperature detector (RTD) that provides accurate temperature measurement.

What is the control accuracy?

The control accuracy is ±0.05 °C at steady state. This means the controller maintains the temperature within this tolerance once the system has stabilized.

What are the electrical requirements?

The supply voltage is 24 V DC ±10% with reverse polarity protection. Power consumption is ≤5 W excluding load. The output load is 10–30 A for resistive loads. Always confirm these values with the manufacturer for your application.
