Hydrogen pressure sensor.

Hydrogen gas presents difficulties when it comes to pressure sensors that needs to be considered when selecting the correct sensor configuration. It features the proprietary krystal bond technology pressure sensing element. Now tested to a variety of hydrogen and automotive standards te s hydrogen series introduces the new ast2000h2 series hydrogen pressure transducer which combines high quality mechanical design for hydrogen measurment with hgh performance digital compensation for increased effectiveness. All of our hydrogen products can be viewed here.

This sensor is designed for applications including pem fuel cells on board vehicle cylinder pressure measurement hydrogen regulator pressure measurement hydrogen filling stations hydrogen storage containers and test stand equipment. In the case of pressure sensors in particular thin membranes required for measuring pressure play a decisive role. With our t bridge technology we solve problems as hydrogen embrittlement and can support you to achieve the strong safety requirements. First sensor is on board with high and medium pressure sensor solutions for fuel cell cars.

In hydrogen powered vehicles the gas in the h 2 storage tank has to be regulated through a series of control valves before reaching the fuel cell. Or to put it simply the pressure sensor starts leaking or is completely destroyed.

In the worst case this results in cracks in the material. A hydrogen sensor is a gas detector that detects the presence of hydrogen they contain micro fabricated point contact hydrogen sensors and are used to locate hydrogen leaks. Pressure instruments play an important role in this process but standard pressure sensors fall short in hydrogen applications because they lack suitable sensor materials. Two of the most common sensor concerns in hydrogen applications are hydrogen embrittlement and hydrogen permeation.

Many of our products have digital communication capabilities for easy monitoring and control. Hydrogen levels in the air can be measured in units of parts per million ppm. The ast4500 and ast4510 level sensors are completely sealed for submersion yet vented through the cable to correct for barometric pressure changes. For pressure ranges from 0 1 to 0 100 psi that require a wide range of media compatibility the submersible series is an excellent solution to level monitoring for indoor and outdoor applications.

Hydrogen atoms that diffuse into the metal grid change the strength of the material.
