Controllers are vital components in automated systems such as industrial automation and process control. Among them, the AKT92131201 temperature controller is a versatile device designed for ease of use, reliability and accurate performance in a range of applications. This article takes a detailed look at the AKT92131201 application field, design parameters and working principle.

Application Field

The AKT92131201 is a precision, temperature controller designed for industrial applications. It can be used to regulate temperature in both cooling and heating systems, making it suitable for a wide range of applications including process control, packaging machines, food processing, heat exchangers, compressors, and crucible furnaces. It is also suitable for general purpose laboratory and research applications.

The AKT92131201 features a 5-digit, backlit LCD readout which provides accuracy in increments of 0.1℃ with a resolution of 0.01℃. It is easy to operate, with dual-reading displays of the setpoint and process value. It is also equipped with a user-friendly control knob for adjusting the temperature setpoint. The device can be integrated with various types of temperature sensors, such as thermistors, RTDs and thermocouples to provide consistent control and accuracy.

Design Parameters

The AKT92131201 has an input power rating of 85-250V AC, 50/60 Hz, and a power consumption of 3W. Its temperature measurement range is -50℃ ~ 300℃, and its temperature control range is 0 ~100℃. It has a microcontroller-based PID (proportional, integral, derivative) algorithm for temperature control, with adjustable proportional, integral, and derivative terms.

The device features two adjustable outputs, with either a switching output or an analog output. The switching output can be used to control a relay, contactor, or other switching device, while the analog output can be used for a heating or cooling device, DC actuator, or other variable-power device. In addition, the device is equipped with two adjustable setpoints, two alarm outputs, two alarm relays, one analogue retransmission, and one random number lock.

Working Principle

The AKT92131201 temperature controller uses a microcontroller-based PID algorithm for temperature control. This algorithm works by adjusting the output of the device based on the process temperature readings. The PID algorithm takes into account the proportional, integral, and derivative terms of the process, compares them to the desired setpoint temperature, and makes necessary adjustments. The proportional term is responsible for the initial response of the device, with higher coefficient values resulting in faster responses. The integral term is responsible for minimizing the offset error, and the derivative term is responsible for controlling the rate of the output.

The AKT92131201 also features two adjustable outputs, each with a separate setpoint. The two setpoints are used to switch between cooling and heating operations. When the process temperature is below the lower setpoint, the device will switch to heating mode; when the process temperature is above the higher setpoint, the device will switch to cooling mode. In addition to the two output channels, the device also features two alarm outputs, two alarm relays, one analogue retransmission, and one random number lock.

The AKT92131201 is a high-performance, reliable temperature controller with excellent accuracy and ease of use. Its flexibility and ease of integration make it an ideal choice for a wide range of applications, from process control to laboratory work. Its accuracy and reliability ensure consistent temperature control for efficient operation.
