Temperature Sensors - RTD (Resistance Temperature Detectors) are widely used in a variety of industries, ranging from the food and beverage sector to scientific research and aerospace and defense applications. The PPG102A5 is a type of RTD device designed with properties that make it well-suited to measuring temperatures in a wide range of conditions. This article explores the application field and working principle of the PPG102A5.

The PPG102A5 is a miniature, open-circuit RTD element with a stainless steel construction. It features three connections at its base, two of which are interchangeable. This enables the device to be mounted in various orientations while still operating accurately. The compact size of the PPG102A5 is another key feature; it can measure temperatures in installations with limited space. The device can also handle temperatures up to 500°C, so it is well-suited to applications in harsh environments.

The working principle of the PPG102A5 is based on the Wheatstone Bridge principle. The device consists of an element made up of an alloy with a known temperature coefficient. When the device experiences a change in temperature, the resistance of the element changes in proportion with the temperature change. A bridge circuit consisting of four resistors then amplifies this change in resistance and the bridge output is measured by an analog voltage output.

The PPG102A5 is used to measure temperature in a range of industrial applications. Its small size and stainless steel construction make it well-suited to use in food processing and other environments where hygiene is important. The device is also used in the scheduling and control of heating systems and is suitable for temperature measurements in water and gas systems. Other applications include measuring temperatures in hydraulic systems, motor bearings, electrical cabinets and ventilation systems.

The PPG102A5 also has a range of features that make it suitable for aerospace and defense applications. Its stainless steel construction makes it resistant to corrosion and vibration, while its small size allows it to be installed in tight locations. In addition, the device provides a linear output that is unaffected by the presence of noise and environmental disturbances.

In summary, the PPG102A5 is a miniature open-circuit RTD sensor capable of measuring temperatures up to 500°C. The device works on the Wheatstone Bridge principle and is suitable for use in a wide range of industrial applications, from food processing to aerospace and defense. Its small size and robust construction make it an ideal choice for temperature sensing in harsh environments.
