What Klay Instruments does
Klay Instruments B.V. is a privately held Dutch manufacturer of process instrumentation, founded in 1978 and headquartered in Dwingeloo, Netherlands. The company designs and produces all-stainless-steel instruments for pressure, level, flow, and temperature measurement — including pressure transmitters (CER, 8000, 2000, 3000, 4000 series), differential pressure transmitters, submersible level transmitters (Hydrobar, HydroCer, AquaCer families), level switches, Pt100 temperature sensors, and intelligent temperature transmitters (TT-2000, TT-4000). Core technical capabilities include flush diaphragm sensor design, ceramic and metallic measuring cells, microprocessor-based electronics, and support for industrial communication protocols (HART, Profibus PA).
Klay Instruments serves industrial customers across seven primary verticals — food, pharmaceutical, pulp and paper, water and wastewater, chemical and petrochemical, marine and shipbuilding, and offshore — through a global distributor network spanning more than 50 countries, supplemented by direct manufacturer sales in the Netherlands. The portfolio is differentiated by regulatory and certification coverage including ISO 9001:2015, ATEX, IECEx, EAC, SIL2 functional safety, EHEDG and 3-A hygienic certifications, plus marine type approvals from Lloyd's Register, DNV, ABS, CCS, Bureau Veritas, and Korean Register.
Revenue is generated through hardware sales of process instrumentation, with pricing established on a quote basis per configuration and application. The go-to-market is primarily channel-driven through distributors, with no public pricing, no disclosed revenue figures, no external funding, and no named end-customer logos. The company is founder/privately owned with no parent or institutional investor disclosed in available sources.
