What Bourdon does

Bourdon Instruments, headquartered in Stockach, Germany, and operating as part of the Baumer Group, manufactures mechanical process instrumentation including pressure gauges (industrial, solid-front safety, process, utility, capsule, diaphragm, absolute, differential), diaphragm seals (threaded, flanged, hygienic, in-line), pressure and temperature switches, and bimetal and gas-filled thermometers. The portfolio is built around the original Bourdon tube pressure measurement principle developed by Eugène Bourdon in 1849, supplemented by capsule, diaphragm, and bellows sensing technologies, with products manufactured in-house with high vertical range of manufacture across 900+ stock variants and 2,700+ configurable preferential variants. Notable technical capabilities include the WEP5 IoT mechanical safety pressure gauge (marketed as the first of its kind) and an extensive certification footprint spanning ATEX, NACE, Lloyd's Register, nuclear power approvals, 3-A, EHEDG, and FDA 21 CFR Part 11 compliance for safety-critical and hygienic applications.

The company generates revenue primarily through hardware sales via a quote-based pricing model with no public e-commerce, distributing through a global network of regional distributors and direct field/office sales staff organized by industry vertical. Primary customer segments are Process Industries (chemical, petrochemical, nuclear, oil & gas) and General Industries (HVAC, water treatment, machine building, transportation), with secondary exposure to hygienic/food & beverage, pharma, power generation, and an emerging hydrogen energy application area. The go-to-market relies on technical consultation, regional distribution partners, and digital product discovery tools (Quick Finder, product selector) feeding into an inquiry/quote process, with no self-service transactional channel. The business is wholly owned by Baumer Group (since 2005 via the former Haenni Instruments AG) and operates a US commercial office in Kennesaw, Georgia alongside its German European headquarters.
