Description

technical field [0001] The invention relates to a device for temperature measurement of centrifugal equipment, in particular to a wireless device for real-time measurement of in-situ temperature of high-speed centrifugal equipment. Background technique [0002] In life science and clinical diagnostic instruments, centrifugal equipment is often used, including centrifugal separators, centrifugal dehydrators, centrifugal extractors, centrifugal fans and centrifugal microfluidic analyzers. After the centrifuge motor rotates, the actual temperature of the sample in the centrifuge components (such as centrifuge tubes, extraction tubes, microfluidic chips, etc.) The change of temperature with rotational speed is a dynamic process. However, a large number of enzyme-catalyzed reaction processes are involved in biochemical related reactions, which are more sensitive to the temperature environment in which the enzymes are located. Therefore, real-time monitoring of the actual reactio...

Problems solved by technology

However, since the components are in high-speed rotational motion, it is necessary to solve the problem of data transmission in the motion state

The existing methods can be divided into wired measurement methods and wireless measurement methods. Among them, the wired measurement method can realize the transmission of electrical signals during rotation by setting a temperature sensor in the centrifugal component and setting a brush slip ring through the motor shaft. However, this method has large friction during high-speed rotation and the measurement data is easily disturbed; the wireless temperature measurement method usually adopts the infrared wireless temperature measurement method, which is a non-contact temperature measurement method, which has large measurement errors and the reflection coefficient of the illuminated surface A series of problems such as large impact and lack of real-time performance of temperature feedback lag

Therefore, the existing technology cannot provide a measurement method for in-situ direct measurement, accurate data, stable reliability and real-time transmission
