Leak test for Cryogenic Heat Exchanger

Abstract

A Cryogenic temperature control system based on temperature monitor having multiple channels has been used for recording and monitoring the various temperature in Cryogenic Heat exchanger which is further used for liquid helium test facility. The effectiveness of heat exchanger can be maintain by the temperature that will be measured at inlet and outlet of the prototype heat exchanger. The temperature range of the tested heat exchanger is 77 k to 300 k. This paper tells the crucial role of temperature in cryogenic system and describes the process. Various sensors has been placed in the system and different temperature readings has been taken in LabVIEW where it can be monitor and log the varying temperature value of a cryogenic heat exchanger with the help of data acquisition system (DAQ). Siemens PLC (Programmable logic control) S7 300 has been introduced for controlling the cryogenic heat exchanger process.
