Frequently Asked Questions

What is a Pt100 controller and how does it work?

A Pt100 controller is a temperature controller that uses a Pt100 resistance temperature detector (RTD) as the sensing element. The Pt100 sensor changes its electrical resistance with temperature, and the controller measures this resistance to determine the temperature. It then compares the measured temperature to a set point and activates outputs (heating or cooling) to maintain the desired temperature. Our controllers use high-precision analog-to-digital converters and digital compensation to ensure accurate temperature readings and control. They feature PID algorithms that adjust output power responsively, providing stable and precise temperature management suitable for industrial applications.
While our Pt100 controllers are specifically designed for Pt100 sensors, many models offer multi-input capability, allowing them to accept other sensor types such as thermocouples (K, E, J, etc.) or thermistors. For instance, the XRKC XMTG-2001 supports both K/E thermocouples and Pt100 inputs. However, to achieve the highest accuracy and performance, it is recommended to use the sensor type for which the controller is calibrated. Please check the product specifications or consult our technical support team to determine if your desired sensor type is compatible with a particular model.
Pt100 controllers are used in a wide range of applications where precise temperature control is critical. Common applications include plastic injection molding machines, extruders, packaging machinery, food processing equipment, laboratory ovens, environmental chambers, and HVAC systems. They are also used in chemical processing, pharmaceutical manufacturing, and semiconductor production. The versatility of Pt100 controllers makes them suitable for any process that requires accurate and stable temperature regulation.
Yes, we offer OEM/ODM customization services. You can customize various aspects of the controller, including the input type, output configuration, temperature range, display format, and even the housing color. We can also modify control algorithms or add specific features like timers, alarms, or communication protocols, such as RS485 Modbus, to meet your unique process needs. Our R&D team will work closely with you to develop a solution that fits your application perfectly. Please contact us with your requirements, and we will provide a tailored quote.
Our Pt100 controllers come with detailed user manuals and wiring diagrams. Generally, installation involves mounting the controller in a panel (or on a DIN rail for rail-mounted models), connecting the power supply, sensor, and output devices, and configuring parameters via the front panel. The controllers feature straightforward menus for setting temperature units, alarm limits, and PID values. We also provide technical support and training resources to assist with setup. Additionally, many models offer auto-tuning, which automatically calculates optimal PID parameters, simplifying configuration.
