Digital PID Temperature Controller | Universal Sensor Input | 1300°C

This digital temperature controller uses PID logic to keep heating or cooling steady. It works with a PT100 sensor. The controller also takes K and J type thermocouple inputs. This makes it a flexible choice for projects that need exact temperature control up to 1300℃. Features and Benefits - PID Control - It holds a steady temperature by learning how your system acts. This stops the big temperature swings you get with a basic thermostat. - Universal Input - It works with a PT100 sensor and common thermocouple types. So you can pick the right probe for what you're doing. - Dual Digital Display - It shows the current temperature and your set value at the same time. This lets you check things quickly. - Relay Output - The built-in relay can turn heaters, fans, or alarms on and off directly. It does this based on your settings. Applications - Controlling heating parts in a custom incubator or powder coating oven. - Managing fermentation temperature for making beer or wine. - Adjusting temperature in small kilns, heat presses, or plastic molding machines. Safety & Preparation Always ensure that any electrical work is carried out by a qualified professional. Before installing or testing your PT100 sensor and this 220V AC Digital controller, disconnect the power supply to prevent electric shock. This controller operates with a 0-1300 °C temperature range, suitable for high-temperature applications. Verify that all connections are secure and correctly wired according to the manufacturer's instructions for both the sensor and the controller. This precision sensor controller is designed for accurate temperature management. Identify standard RTD Values An RTD (Resistance Temperature Detector) is a precision sensor that measures temperature by correlating resistance with temperature. The PT100 sensor, commonly used with this controller, has a resistance of 100 ohms at 0 °C. Understanding these baseline values is crucial when you check RTD sensor performance. This digital controller is specifically compatible with PT100 sensors, among others like K-Type and J-Type, allowing for versatile temperature monitoring within its 0-1300 °C operating range. How to Test by Wire Configuration To check RTD sensor functionality, you'll primarily be looking at its resistance. Use a multimeter to measure the resistance across the sensor's leads. The expected resistance will vary based on the temperature and the RTD type. This 220V AC Digital controller is designed to work with PT100 sensors, so you'd expect 100 ohms at 0 °C. Proper testing by wire configuration ensures accurate temperature readings and reliable operation of your temperature control system. A. 2-Wire RTD For a 2-wire RTD, connect the multimeter leads to the two wires coming from the sensor. Measure the resistance directly. It's important to note that with a 2-wire configuration, the resistance of the lead wires themselves can introduce errors into the measurement, especially over longer distances. This digital controller is compatible with PT100 sensors, and while a 2-wire setup is the simplest, it offers the least accuracy for critical applications due to potential wire resistance influence. B. 3-Wire RTD (Most Common) A 3-wire RTD is the most common configuration for improved accuracy. It uses a third wire to compensate for the resistance of the lead wires. To test, connect the multimeter between the two coloured wires (usually red) to measure the resistance of the sensing element. Then, measure the resistance between one of the coloured wires and the white wire. These two readings should be very similar. This compensation method helps to ensure that the 0-1300 °C temperature control is precise when used with this 220V AC Digital controller.
