Phase angle voltmeter, PAV, phase angle volt meter Powertek

With advanced DSP technology and Fast Fourier Transform algorithms this instrument provides a new level of performance and versatility. In addition, the GP102 PAV is competitively priced compared with other traditional PAVs. Specifically targeted at the Synchro/Resolver and LVDT/RVDT marketplace this instrument makes measurements of Phase Angle, In-Phase, Quadrature (90° component), Fundamental and Total Vrms very straightforward. All these measurements are displayed simultaneously on a bright multifunction display. The readout can even be zoomed to enlarge any selected measurement. Isolated inputs allow null, ratio (in-phase, quad, fund, total rms, sum+difference) and gain measurements of key parameters and a reference offset facilitates bridging measurements. A sensitive null meter is included for precise nulling. An on-board reference generator (with optional amplifier) eliminates the need for an external reference; although the unit can be used with an external generator. Using an optional switching matrix (TAF01-U), LVDT, RVDT and resolver measurements can be automated.

Applications

Typical applications for a phase angle voltmeters (PAVs) are found in the area of position sensing 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.
