Using Discrete Fourier Transform algorithms to analyse small siganls buried in noise, the PAV1010A provides capability, performance and versatility not available with traditional PAVs. Targeted at the Synchro/Resolver and LVDT/RVDT marketplace, this instrument simplifies measurements of Phase Angle, Totals, In-Phase, Quadrature (90° component), Fundamental and Total Vrms.  All these measurements are displayed simultaneously on a bright multifunction display.  Isolated inputs allow null, ratio (in-phase, quad, fund, total rms, sum+difference) and gain measurements of key parameters. Bridging measurements are possible with a sensitive null meter for precise nulling.

Typical applications for a phase angle voltmeters (PAVs) are found in the area of position sensing, motion and control. Devices like Resolvers, LVDT (Linear Variable Differential Transformers) and RVDT (Rotary Variable Differential Transformers), convert mechanical movement and position to electrical signals, feeding a control system.  Position sensors are used in a variety of applications like aircraft instruments, aircraft control surfaces, inertial navigation, gyros, autopilot and weapon aiming systems.

PAV upgrade program for military users

For decades the SD10000 phase angle meter has been used worldwide by armed forces and in the aviation sector. Powertek offers an upgrade package converting the SD1000 phase meter to a fully functioning PAV1010A phase angle voltmeter. The benefits are cost savings and continued compatibility with the user's in-house computer test systems, documentation and physical size - whist adding full phase angle voltmeter capability along with multifunction display.

Calibration and World-wide Traceability

All measurements taken with a PAV1010A and SD1000 are traceable to National and International standards; through the measurement standards of Powertek. A certificate of conformance is supplied as required by quality assurance standards such as IEC17025, ISO9001 2015, NVLAP, ANSI NCSL Z540. Independent third-party measurement certification and accreditation is possible using UKAS, A2LA or Z540/NVLAP certificate. Powertek provides optional LV calibration software and attenuators, permitting customers to automate their PAV1010A calibration in house.
