2results about How to "Slow time lag" patented technology

This utility model relates to the field of extraction mixture measurement technology, and discloses an online multi-channel measurement device for the concentration of extraction mixtures. The device includes a housing, with a control cabinet fixedly installed on the left side of the housing. This utility model directly acquires mixture samples from different extraction tanks via an input mechanism, and immediately inputs these samples into a detection mechanism for concentration measurement at a constant temperature. The samples are then discharged by an output mechanism into the corresponding extraction tank, achieving rapid online measurement of the concentration of multi-channel extraction mixtures. Analysis is performed in a detection device next to the production line, effectively managing the number of samples, reducing workload, eliminating sampling time blind spots, and ensuring more accurate test data because the detection environment is consistent with the on-site environment. Relevant data can be quickly fed back to the production department, allowing production personnel to adjust the liquid volume immediately based on accurate data with minimal time lag, significantly improving product yield.

This invention discloses a thermometer fixture suitable for transient processes in cryogenic systems, comprising a front guide tube, a rear guide tube, and a temperature measuring block with a temperature sensor mounting interface. The first end of the front guide tube and the first end of the rear guide tube are respectively connected to process piping, and the second ends of the front guide tube and the rear guide tube are respectively connected to the temperature measuring block. A heat exchange channel is formed inside the temperature measuring block, which communicates with the internal channels of the front and rear guide tubes to form a through-flow fluid channel. The fluid being measured can flow through the heat exchange channel and exchange heat with the temperature measuring block. This invention employs a through-flow structural design, combined with a temperature measuring block made of high thermal conductivity material and an optimized flow channel structure, significantly reducing the thermal inertia and thermal resistance of the temperature measuring system and improving the transient thermal response speed. It is particularly suitable for temperature measurement in cryogenic transient conditions such as superconducting cryogenic systems and modular hydrogen liquefaction equipment in the 20–30 K temperature range.
