Monitor pressures up to 400 bar in medical or industrial gas applications using an all welded stainless steel diaphragm designed for grease free environments.
The DM17 series is engineered specifically for the stringent safety requirements of high-pressure oxygen service, where the presence of hydrocarbon-based lubricants or even standard silicone fill fluids poses a severe risk of spontaneous ignition. By utilizing a completely dry, oil-free sensing cell, this instrument eliminates the potential for fluid leakage into the process stream, which is a critical failure mode in traditional piezoresistive sensors that rely on internal transmission fluids. The sensing element features a robust 17.4PH stainless steel diaphragm, a precipitation-hardened alloy selected for its exceptional fatigue resistance and elastic properties under the high-stress conditions found at 400 bar. This all-welded construction ensures that there are no internal seals or O-rings that could degrade or outgas when exposed to high-purity oxygen, maintaining the integrity of the gas path and preventing the introduction of microscopic particulates.
Calibration technicians and process engineers operating in cylinder filling plants or medical gas distribution networks will benefit from the cleanroom-compliant packaging designed to prevent cross-contamination during transit. The absence of any internal transmission fluid means the DM17 series is not subject to the thermal expansion errors often associated with oil-filled capillaries, providing more consistent 0.5% FS BSL accuracy across varying ambient temperatures. When installed on high-pressure manifolds or hyperbaric systems, the 1/4 NPT male process connection provides a reliable mechanical interface, while the 316Ti stainless steel port offers enhanced corrosion resistance against localized pitting. This makes the unit suitable for long-term deployment in industrial gas skids where maintaining oxygen cleanliness levels is paramount to operational safety and compliance with international gas handling standards such as ASTM G93 or ISO 15001.
