LEC Series Hot Runner Temperature Controller

Product catalog summary

Document Overview

This technical excerpt appears to relate to a control system involving phase angle fired output and PID (Proportional-Integral-Derivative) control algorithms, likely for temperature regulation.

Main Sections and Key Points

Control Method

The system uses a Phase Angle Fired Output method, which is a technique commonly used in power control to regulate the amount of power delivered to a load by controlling the phase angle of the AC waveform.

Control Algorithm

The control is implemented using a PID algorithm, which is a standard feedback control loop mechanism widely used in industrial control systems to maintain a desired setpoint.

Measurement and Resolution

The temperature measurement resolution is specified as 0.05ºC (0.1ºF), indicating a high precision temperature sensing capability, likely from a thermocouple (T/C) sensor.

Summary of Critical Parameters

Control Type: Phase Angle Fired Output
Control Algorithm: PID
Temperature Resolution: 0.05ºC (0.1ºF)
Sensor Type: Thermocouple (T/C)

Implications and Best Practices

Using phase angle firing combined with PID control allows precise power modulation for temperature control applications. The high resolution temperature sensing ensures accurate feedback for the PID controller, improving system stability and performance.
