Description

Thermal bimetallic strip resistance follow-up synchronous continuous measurement system

technical field

The invention belongs to the technical field of strip resistance measuring equipment, in particular to a thermal bimetallic strip resistance follow-up synchronous continuous measurement system.

Background technique

Thermal bimetal strip is a composite strip material that is firmly combined with two or more metal or alloy component layers with different thermal expansion coefficients. It has many superior characteristics and is widely used in the fields of automatic control and instrumentation . The composite strength of the thermal bimetallic strip can be judged by measuring the resistance of the thermal bimetallic strip with a certain length. The existing measurement method is to manually measure the resistance of the fixed-length strip through a high-precision resistance tester. This method has large errors and low efficiency, and cannot meet the needs of automated and efficient production. Secondly, high-precision resistance testers generally use the four-wire method to measure resistance, that is, use two wires to output current, and then use the other two wires to measure voltage. The resistance is obtained according to Kirchhoff's laws, so four contacts are simultaneously in contact with the hot bimetallic strip during the measurement.

Literature search found that Chinese patent literature [Application No.: 201120118365.6] discloses a novel alloy wire and strip meter resistance measuring device, which consists of a platform, a gauge plate, a fixing bolt, a measuring guide, a tester and a measuring wire. The gauge plate is arranged parallel to the middle position on one side of the platform, and is fixedly connected with the platform by bolts. There are two pieces of measuring guides, which are parallel and symmetrical to each other at the two ends of the gauge plate, with a distance of 1M, and are fixedly connected to the gauge plate with bolts. The tester is set at the center of one side of the gauge plate, and the two ends of the measuring wire are respectively electrically connected to the measuring guide and the tester through connectors.

The above scheme uses the two-wire method to measure the strip resistance, but this scheme cannot realize the continuous measurement of the strip resistance, and the resistance measurement efficiency is low, which cannot meet the production needs; secondly, this scheme is not suitable for the measurement of the four-wire method. , the cost of the existing resistance measuring instrument for measuring the resistance of the strip through the four-wire method is relatively high, the structure is complex, and the practicability is poor.
