Mount Olive, N.J. American Sensor Technologies (AST) has expanded its hydrogen-compatible sensor line with the Model 5000 wet/wet differential pressure sensor that measures the differential pressure of hydrogen and other gases.
Featuring AST's Krystal Bond Technology, the Model 5000 pressure sensor does not contain internal O-rings or fluid-filled cavities, which eliminates the chance of hydrogen permeation or system contamination from silicone oil. The diaphragm is constructed of 316L stainless steel wetted materials that resists hydrogen embrittlement for high reliability. This design also provides excellent over-range and burst protection (5x rated line pressure or 2,000 psi, whichever is less) ratings for system safety in the most extreme conditions, said the company.
Model 5000 pressure sensors are CE EN61326 certified. They feature a high level (100 V/m) of both EMI/RFI protection and shock/vibration resistance. A stainless steel housing welded over the electronics maintains an IP-66 rating. Voltage and current outputs are available over a wide operating temperature range of -40° to 85°C (-40 to 185°F). Accuracy specifications are less than ±0.3% BFSL, including non-linearity, Hysteresis, and non-repeatability.

Hydrogen-compatible packaging makes the Model 5000 pressure sensors suitable for hydrogen pipeline instrumentation, filling stations, compressors, PEM Cells, and other hydrogen fuel cell applications. Bi-directional and uni-directional pressure ranges are available for applications with line pressures up to 1,000 psi. In the event that either pressure port is at full line pressure and the other at zero, no damage will be done to the pressure transducer, according to the company.
Pricing for the Model 5000 starts at $425 each with quantity discounts starting at ten pieces. Delivery is about three weeks for one to nine units.
