GLSEQ’s H2-100 is a nuclear safety-related, direct-measurement monitoring sensor that detects and measures hydrogen continuously.
The GLSEQ H2-100 Hydrogen Detection System provides real-time hydrogen gas partial pressure measurements using a unique chemiresistive sensor that converts hydrogen to an electrical signal. The sensor signal is derived by the change in electrical properties from the reversible adsorption of hydrogen in the palladium sensor.
This type of MEMS (micro-electromechanical system) Hydrogen sensor was first used in NASA and aerospace applications and has been modified for use in nuclear power applications. The sensor operates during normal operation as well as during and after a severe accident. This real-time data makes it possible to continuously monitor hydrogen conditions as well as understand the time distribution of hydrogen gas after an accident.
Initially developed for use in NASA applications, GLSEQ’s hydrogen sensors provide high accuracy across a high range of conditions such as:
While most current sampling systems are limited in their hydrogen measurement range to a maximum of 10% hydrogen concentration.
GLSEQ’s hydrogen sensors directly measure hydrogen partial pressure in a concentration range of 0 to 100% hydrogen.
GLSEQ’s hydrogen sensors provide real-time hydrogen monitoring which provides critical and accurate data in time for effective accident mitigation.
The controllers can collect data measurements as fast as 1/10th of a second. No more waiting on your sampling system!
Hydrogen gas sampling systems require constant maintenance to adjust heat tracing, adjust flow controllers, and test gas analyzers, isolation valves, pumps, and motors.
GLSEQ Hydrogen sensors do not require maintenance and surveillances can be done remotely and online.
* The H2-100 requires the GLSEQ single-channel hydrogen controller or the 4-channel hydrogen controller to operate.
