Cryogenics Fluid Level Sensor – 20Bar

Hylium Industries, Inc.

Capacitance-based level sensor and monitor for liquid hydrogen
Real-time data recording function (SD card)
BNC connector interface
Designed for cryogenic fluid measurement

The HYLP is a capacitance-based cryogenic fluid level sensor and monitoring system designed for liquid hydrogen (LH2) applications. The system consists of a probe (HYLP050C) and a monitoring unit (HYLM001N). It supports measurement of liquid hydrogen levels using capacitance sensing and operates across a wide temperature range from -269 °C to 200 °C. The system includes a BNC connector interface, a 2.4-inch TFT display (240 × 320 resolution), and a real-time data recording function via SD card. The sensor supports a capacitance range of 10–1000 pF with a measurement resolution of 0.7 pF, enabling precise monitoring in cryogenic environments.
