What SensorLink does
SensorLink Corporation, founded in 1985 in Ferndale, Washington, manufactures a specialized portfolio of live-line, high voltage sensing instruments for the global power utility industry. The company originated as an engineering and consulting firm and pivoted into manufacturing in 1988 after developing a patented sensor that operates safely in high voltage environments up to 500KV, exceeding prior live-line measurement tools in accuracy, external current rejection, and measurement range. Its first product, the Ampstik, was released in 1989, and the patented sensor architecture underpins substantially all of the current lineup.
The product portfolio is organized into two core categories — meters (including Ampstik®+, Radio Ampstik, Voltstik, Qualstik, Ohmstik, Amp Litewire, Volt Litewire, Phase Meter, and the Troubleman's Kit) and recorders (Amcorder and Varcorder) — plus a maintained legacy product line (original Ampstik®, TMS Meters, earlier Litewire versions). Instruments are designed for live-line work on both distribution and transmission circuits, with select products offering wireless remote reading up to 50 feet. The 2023 addition of the Phase Meter and a redesigned Radio Ampstik/Remote Receiver represent the most recent extensions of the product surface.
SensorLink operates a sales-led go-to-market through a global network of authorized representatives supplemented by direct telephone ordering from its Ferndale headquarters, with products described as "standard utility issue" in over 70 countries. The company is privately held, incorporated in Washington State, has no disclosed parent company, no disclosed funding rounds, no public revenue, and a headcount band of 11-50 employees. Customers are exclusively power utilities, with the end users being utility linemen and troublemen performing field measurement and troubleshooting.

SensorLink competitors and assessment
Company assessmentDirect peers
- AEMC Instruments: AEMC manufactures electrical test and measurement instruments (current clamps, power quality analyzers, ground testers) sold to utility and industrial users. Overlaps directly with SensorLink in high-voltage/current measurement tools for field linemen and electricians.
- Megger: Megger is a long-established manufacturer of electrical test equipment for power utilities, including insulation testers, transformer analyzers, and high-voltage measurement tools. Direct overlap with SensorLink's utility lineman/troubleman customer base and measurement instruments.
- Doble Engineering: Doble provides diagnostic instruments, software, and services for electrical power utilities, focused on condition monitoring and testing of transformers, breakers, and protection systems. Competes with SensorLink for utility asset-measurement budgets and field diagnostics workflows.
- Arbiter Systems: Arbiter Systems manufactures GPS-synchronized power system measurement instruments (substation clocks, meters) explicitly referenced in SensorLink's own Litewire product documentation as a complementary device. Closest peer in measurement category served.
- OMICRON Electronics: OMICRON builds secondary injection and electrical measurement/testing equipment used by utility protection engineers and field crews. Overlaps with SensorLink in advanced electrical measurement for utility T&D operations.
- Beckwith Electric: Beckwith Electric designs protection, control, and monitoring products for utility substations and distribution systems. Adjacent to SensorLink for utility measurement, with overlap in protection-related field instrumentation and controls.
Broad incumbents
- Fluke Corporation: Fluke is the broad incumbent in electrical test and measurement with a much larger portfolio (handheld DMMs, power quality, thermal imaging). Competes with SensorLink in current/voltage measurement but offers broader product breadth rather than HV-live-line specialization.
- Schweitzer Engineering Laboratories (SEL): SEL is a major power-system protection, metering, and automation vendor serving utilities globally. While SEL is much broader and more automation-focused, it competes for utility measurement-instrumentation budgets adjacent to SensorLink's territory.
