The invention discloses a bearing platinum thermal resistor. The bearing platinum thermal resistor is characterized in that a resistance casing pipe is connected with a junction box through a clamp sleeve connector, an armored platinum resistor element is arranged in an inner cavity of the resistance casing pipe, the armored platinum resistor element extends into the junction box, and is connected with a wiring board in the junction box, a damping leakage jamming rod sleeves the resistance casing pipe, a clamp sleeve sleeves the resistance casing pipe and wraps the resistance casing pipe, the clamp sleeve is located between the damping leakage jamming rod and the junction box, the damping leakage jamming rod comprises a first jamming rod and a second jamming rod which are coaxially connected, the first jamming rod is located on one side of the damping leakage jamming rod, close to the junction box, the first jamming rod is connected with a first fastener which sleeves the resistance casing pipe, and thereby is fixedly connected with the clamp sleeve, an elastic telescopic pole sleeves the second jamming rod, a clamp sleeve thread connector sleeves a portion of the resistance casing pipe, close to one end of the second jamming rod, and the clamp sleeve thread connector is connected with a second fastener. The bearing platinum thermal resistor is convenient and quick to install and adjust, and good in shock resistance and impact resistance, reduces operation difficultly, and improves measurement accuracy.
Description
technical field [0001] The invention relates to the technical field of temperature sensors, in particular to a bearing platinum thermal resistance. Background technique [0002] Temperature is a basic physical quantity. All processes in nature are closely related to temperature. As a sensor for measuring temperature, temperature sensors can convert temperature information into usable output signals. Temperature sensors have a wide range of applications and a huge market share. [0003] Bearing platinum thermal resistance is suitable for temperature measurement of bearings with bearing equipment in power plants and other shockproof occasions. In order to make the shock resistance and impact resistance of bearing platinum thermal resistance meet the relevant requirements of national standards, the structure is too complicated in design, resulting in poor versatility and difficult assembly. Contents of the invention [0004] In order to solve the technical problems in the ba...
