Abstract

Abstract

En 中文
• A field-deployable internal DP transmitter for various cryogenic tanks is developed. • Direct compatibility with commercial dewars enables portable level monitoring. • The Portable IDP-LT ensures intrinsic safety with no electronics in submerged areas. • LHe validation confirms industrial readiness with 4.92 mm mean absolute deviation. • The measured heat inleak of only 0.365 W allows practical use with minimal boil-off.
