Technology Popularization | Working Principle of IO-Link Temperature Sensors

In modern industrial automation, temperature control and monitoring are crucial for ensuring process safety, improving production efficiency, and optimizing product quality. As a company dedicated to technological innovation and high-quality service, we have launched a temperature sensor based on thermistors integrated with IO-Link functionality. This sensor, with its high precision, reliability, and intelligent features, has become the preferred solution for many industrial applications.

Working Principle of the Temperature Sensor

The sensor measures temperature by utilizing the linear characteristic of platinum resistance changing with temperature. Pt1000 (platinum) has a resistance of 1000 ohms at 0°C, and this resistance changes with temperature. This change is highly linear, ensuring high accuracy and stability in temperature measurement.

Advantages of Pt1000 Temperature Sensor

High Precision

Pt1000 sensors are renowned for their precise measurement accuracy. Due to the stable physical and chemical properties of platinum, Pt1000 sensors can provide accurate temperature measurements over a wide range. This is particularly important for applications requiring high-precision temperature control, such as pharmaceuticals, food and beverage, metallurgy, and machine tools.

Long-Term Stability

Pt1000 sensors have excellent long-term stability. The resistance value of platinum changes very little over time, allowing Pt1000 sensors to maintain high accuracy in temperature measurement over long periods. This long-term stability reduces the need for sensor maintenance and calibration frequency, thereby lowering operating costs.

Advantages of IO-Link Technology

IO-Link is a point-to-point communication technology for sensors and actuators that simplifies device integration and maintenance, offering the following main advantages:

• Digital Communication: IO-Link can convert the sensor's analog signal into a digital signal, providing higher signal transmission accuracy and anti-interference capability.


• Remote Configuration and Diagnosis: With IO-Link, users can remotely access the sensor's configuration parameters and status information for real-time monitoring and fault diagnosis, improving device operational reliability.


• Data Transmission: In addition to temperature data, the sensor can transmit self-diagnostic information (such as internal temperature, operating hours, etc.), providing strong support for equipment predictive maintenance.


• Simplified Wiring: IO-Link uses standard three-wire transmission, simplifying wiring and installation processes, and reducing installation costs.

Key Factors in Selecting Temperature Sensors

When selecting temperature sensors, the following key factors need to be considered to ensure optimal performance in specific applications:

Temperature Range and Accuracy

Different types of temperature sensors are suitable for different temperature ranges and may be more accurate within a specific range. Therefore, it is essential to check the sensor's datasheet before purchasing to ensure its applicable temperature range matches the expected range of the application.

Size and Packaging

The size and packaging style of the temperature sensor determine its suitability for the application space. If space is limited, a smaller device is required. The packaging style also affects how the sensor connects to the application and measures temperature, making it an important consideration.

Environmental Conditions

The operating environment of the sensor significantly impacts its stability and accuracy. Humidity, vibration, and electrical noise can all affect the sensor's performance. To ensure accurate measurement results, it is necessary to assess the sensor's usage environment and take necessary protective measures, such as using wear-resistant and corrosion-resistant metal sheaths.
