YW-03 type thermal expansion sensorDetailed product description：

1、 Introduction
The YW-03 thermal expansion sensor is mainly used to measure the expansion displacement of steam turbine cylinders. It can be paired with the GW-RZ thermal expansion stroke monitoring instrument to complete functions such as display, alarm, and constant current output of expansion displacement. It can also be paired with CWXC stroke displacement transmitter

2、 Technical parameters
1. Measurement range: 0-25mm, 0-35mm, 0-50mm
2. Linear error: ± 1%
3. Working temperature: ≤ 100 ℃
4. Humidity: ≤ 85%

When an iron core moves within a spiral coil, the impedance inside the coil changes. When a constant voltage is supplied between the coils, these impedance changes are proportional to the movement of the iron core, that is, the change in voltage is linearly proportional to the displacement of the iron core. According to the principle of differential transformers, the displacement of the iron core can be measured, and the displacement of the object can be determined.
