Mitutoyo 519-562A Offers

This instrument uses a differential inductance displacement sensor energized by a 5kHz AC exciting voltage applied across two identical series-connected coils, L1 and L2. An iron core connected to the stylus moves close to both cores and varies the impedance of each coil depending on its position, and the voltage at the junction between the coils varies as the impedance difference.

Two resistors, R1 and R2, form a bridge circuit with the coils and the bridge output voltage drives electronic amplification and conditioning circuits to provide a voltage signal proportional to displacement of the stylus.

Features

• Digital display
• Calculation mode ±A, ±B, and ±A±B
• Can connect 2 probes to the unit at a time
• The EV-16A allows 6 probes to be connected simultaneously to one unit
• The use of the RS link enables easy construction of a multi-point measuring system that allows a maximum of 10 units (60 probes)
• I/O outputs such as RS-232C, BCD, tolerance judgment and segment are selectable
• Peak measurement and arithmetic operation between axes (in the same unit) are also possible in addition to normal measurement for each axis

Electronic Gaging Systems

Suitable for a variety of applications from inspection rooms to production lines, the 519 series high-accuracy Mu-Checker electronic gaging systems is adaptable based on customer demands.

High-resolution lever-head probes allow multi-point measurements of small parts, flatness and straightness measurement on X/Y table, as well as runout measurement of shafts. The cartridge head-type is easily built into equipment because of its compact shape. Probes are offered with a standard measuring force of 0.2N, or a low measuring force of 0.02N. Optional styli, extension rods and brackets are available.

Both digital and analog models offer zero setting with the touch of a button. Additional models allow for multi-probe measuring systems.
