A new measurement module enables precise temperature measurements in liquid hydrogen systems. The system with four separate input channels supports common cryogenic sensors and minimizes unwanted sensor heating through its special design.
Handling liquid hydrogen at minus 253 degrees Celsius requires maximum measurement precision. The new Q.bloxx A105 CR measurement module achieves this through minimal sensor excitation of 7.5 microamperes, preventing unwanted sensor self-heating.
Modular System for Complete Monitoring
Using a 24-bit converter, the system performs ten measurements per second per channel. Support for Cernox® and TVO sensors with measuring ranges up to 25 kΩ and sensor-specific linearization with up to 32 calibration points guarantee precise long-term measurements.
As a component of the modular Q.series X system, the module enables complete monitoring of thermal, mechanical, and electrical parameters under extreme conditions when combined with additional measurement units. Primary applications include temperature control of LH2 storage tanks and transport containers, as well as system tests for optimizing operating conditions and minimizing boil-off losses.
Foundation for LH2 Infrastructure Expansion
The demand for precise measurement technology in the cryogenic sector is increasing with the expansion of the hydrogen economy. German plans anticipate liquid hydrogen storage capacities of over 100,000 cubic meters by 2030 – infrastructure that depends on exact measurements.
