Based in Warriewood, New South Wales, SensMar Pty Ltd is an Australian engineering and manufacturing firm dedicated to process control instrumentation within the global maritime and industrial sectors. Established in 2010, the company operates as a second-generation, family-owned enterprise that emerged from a long lineage of instrumentation expertise, specifically drawing upon the technical heritage of KDG Instruments and Measurement Resources Pty Ltd. SensMar was founded to address a critical gap in the marine market: the continued need for specialized liquid level and pressure sensors that support both modern shipbuilding and the maintenance of existing fleets.
The company’s primary operational focus revolves around the design, manufacture, and calibration of hydrostatic tank contents gauges, level switches, and pressure transmitters. A defining characteristic of SensMar’s role in the maritime industry is its ability to engineer direct replacements for legacy systems, including discontinued models from major historical manufacturers. This capability allows ship owners and operators to maintain or retrofit aging vessel infrastructure without requiring extensive structural modifications. The firm’s manufacturing facility in Sydney includes specialized capabilities for welding, machining, vacuum leak testing, and instrument calibration, ensuring that components meet rigorous marine standards.
SensMar serves a diverse international client base, exporting a significant portion of its output to shipbuilders and owners in Europe and the United States. Its technology is utilized across a wide spectrum of maritime environments, ranging from commercial shipping and cruise liners to naval defense applications. The company has secured recognition from the Australian Department of Defence, holding a Letter of Recognised Supply (LoRS), and its equipment has been deployed on high-profile assets such as the *Collins Class* submarines and various major cruise vessels.
Quality assurance is central to SensMar’s operations, with management systems accredited to ISO 9001:2015 standards. The company regularly undergoes factory inspections by leading marine classification societies, including Bureau Veritas and Lloyd’s Register, to ensure compliance with international maritime safety regulations. Through its focus on "through-life support," SensMar provides the maritime sector with essential engineering continuity, delivering reliable sensing solutions that safeguard critical vessel functions from the engine room to the bridge.
