Mitutoyo EV-16A 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.

To calibrate the EV-16A properly, be sure to purchase dedicated display unit D-EV. When multiple units of EV-16A units are to be used, at least one D-EV unit is required.

As a power supply is not supplied as standard, an appropriate power supply with a current capacity of 1A or more must be provided for each EV-16A.

Features

• I/O outputs such as RS-232C, BCD, tolerance judgment and segment are selectable
