Non-Intrusive Measurement Sensors & Instrumentation

A non-intrusive flow meter measures fluid flow from outside a pipe or system without cutting into the pipe or interrupting flow. Similar in principle to SensorData's non-contact torque sensors, these instruments use external sensing elements — such as ultrasonic transducers — to gather measurements without altering system behavior or requiring system shutdown for installation.

Rotary transformer sensors use magnetic induction to transmit power and signals across a small air gap with no physical contact, eliminating wear and maintenance. Slip ring sensors use brushes in physical contact with rotating rings. Rotary transformer designs offer longer service life, lower noise, and are better suited to high-speed and high-cycle applications.

Yes. The SYNTH Wireless Rotary Torque Sensor is intrinsically safe and certified for ZONE 1 DIV 1 explosive environments. It is immune to EMI, ESD, and nearby metal interference, making it suitable for oil drilling, petroleum mining, and engine testing in flammable or caustic atmospheres where wired sensors would pose safety risks.

SensorData offers multiple wireless options: the SYNTH series transmits over 500 feet, the BT4000 Series transmits up to 100 feet, and the Turnkey Conveyor Diagnostic System transmits up to 750 feet. All operate in license-free ISM bands at either 2.4 GHz Bluetooth or 915 MHz frequencies, eliminating cabling in challenging environments.

SensorData's non-intrusive sensors serve aerospace, automotive, defense, oil and gas, electric vehicle testing, railroad, and industrial manufacturing sectors. Common applications include aircraft fuel pump test stands, EV drivetrain testing, engine and transmission testing, conveyor predictive maintenance, viscosity measurement, and life cycle testing of motors, pumps, compressors, and turbines.

Yes. SensorData provides free in-house calibration when their electronics are used, and fee-based calibration with customer-supplied electronics. Several models comply with IEEE Standard 1451.4 TEDS and Army-Navy standards AND 20002 and AND 10262. Calibration documentation and remote shunt calibration capabilities are available on select models such as the BT4000 Series and SYNTH.
