They’re ideal for ROVs, AUVs, and other subsea instrumentation in long-term deployments where reliability is important.\u003c\/p\u003e\n\u003cp\u003eBarXT sensors use the M10 bulkhead penetrator form factor machined from 316 stainless steel, coated with black oxide to reduce galvanic corrosion, and feature a front cover that protects the sensing element from physical damage. BarXT is built to handle harsh marine environments and extended missions.\u003c\/p\u003e\n\u003cp\u003eThe BarXT line uses the Keller 4LD series sealed pressure and temperature sensor, and includes four models to cover a range of depths and resolutions:\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eOperating Range\u003c\/th\u003e\n\u003cth\u003eApproximate Depth\u003c\/th\u003e\n\u003cth\u003eResolution\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eBar3XT\u003c\/td\u003e\n\u003ctd\u003e0–3 bar\u003c\/td\u003e\n\u003ctd\u003e20 m\u003c\/td\u003e\n\u003ctd\u003e0.091 mbar (0.9 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBar10XT\u003c\/td\u003e\n\u003ctd\u003e0–10 bar\u003c\/td\u003e\n\u003ctd\u003e100 m\u003c\/td\u003e\n\u003ctd\u003e0.31 mbar (3.12 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBar30XT\u003c\/td\u003e\n\u003ctd\u003e0–30 bar\u003c\/td\u003e\n\u003ctd\u003e300 m\u003c\/td\u003e\n\u003ctd\u003e0.92 mbar (9.36 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBar100XT\u003c\/td\u003e\n\u003ctd\u003e0–100 bar\u003c\/td\u003e\n\u003ctd\u003e1000 m\u003c\/td\u003e\n\u003ctd\u003e3 mbar (31 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/geI2UIC6IPM?feature=oembed\" allowfullscreen\u003e\u003c\/iframe\u003e\n\u003cfigure\u003e\n\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1017\/5745\/2662\/files\/BARXT-VP-ITW.jpg\" alt=\"\"\u003e\n\u003c\/figure\u003e\n\u003ch3\u003ePerformance Under Pressure\u003c\/h3\u003e\n\u003cp\u003eAll BarXT models also measure temperature, accurate to ±2 °C.
