PM Special Measuring Systems

What PM Special Measuring Systems does

PM Special Measuring Systems B.V. is a privately-held Dutch specialist headquartered in Enschede that has developed, manufactured, and serviced Zero-flux current measuring systems since the 1970s. The company was the first to commercialize the Zero-flux methodology originally developed at CERN, enabling non-intrusive measurement of AC and DC currents up to 60kA with scientific-class accuracy and stability. Its product portfolio spans three lines: MACC-series precision measuring systems (MACC150 for PCB integration, MACC 2 Plus for high-accuracy low-noise applications, form/fit/pin compatible with the legacy MACC plus), electronics modules (STACC, TOPACC, CURACC, and HITACC families in 19-inch 1U, Eurocard, and high-current variants), and measuring heads (MH series for science, H series for HVDC, with bore sizes from 34mm to 470mm and bushing variants supporting up to 150 kV isolation), plus accessories such as burden amplifiers, the Diagnostics Box, and PSU Eurocard supplies.

The company's business model is sales-led direct B2B enterprise, with custom-configured solutions and long-tail servicing across multi-decade installations. Revenue streams are hardware sales of complete measuring systems (measuring heads paired with electronics modules) and professional servicing and support for the operational lifecycle. Pricing is not publicly disclosed; quotations follow direct technical consultation. Three customer segments are addressed: scientific research (including particle accelerator current control for multi-kilometer beam paths), HVDC power transmission (indoor, outdoor, onshore, offshore), and industrial power analysis (test and measurement, power analysis, efficiency improvement). Manufacturing, design, development, and servicing are covered by ISO 9001:2015 certification.

Go-to-market relies on direct enterprise sales with technical consultation, supported by a documentation-heavy website offering downloadable datasheets, manuals, dimensional drawings, and the ISO 9001 certificate. The company maintains a small employee base in the 11-50 range, declares a global footprint with no geographic restrictions, and operates without disclosed channel partners, distributors, or institutional investors.

Core offering

PM Special Measuring Systems B.V. develops, manufactures, and services Zero-flux current measuring systems based on CERN technology from the 1970s. The company designs precision DC and AC current transducers, electronics modules, and measuring heads for scientific research, HVDC power transmission, and industrial applications, supporting measurement ranges up to 60kA with bandwidths from DC to 30kHz.

Product overview

PM Special Measuring Systems B.V. develops, manufactures, and services Zero-flux current measuring systems, having introduced this technology in the 1970s. The product portfolio consists of three main categories: Science (for research applications), HVDC (for high-voltage direct current power transmission), and Industry (for industrial power measurement). Core product lines include MACC (Multi Amplifier Current Converter) series precision measuring systems ranging from MACC150 (smallest, PCB-integrated) to MACC 2 Plus (high accuracy, low noise); electronics modules (STACC, STACC-HC, TOPACC, TOPACC-HC, CURACC, HITACC series) that process and convert current measurements; and measuring heads (MH and H series) that detect magnetic flux. The company also offers supporting accessories including burden amplifiers, power supplies, diagnostic tools, and downloadable resources including datasheets, manuals, and ISO9001 certification documentation.
