Description
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 Peak measurement and arithmetic operation between axes (in the same unit) are also possible in addition to normal measurement for each axis Major Functions Major Functions External control (zero-setting, presetting, etc.) Direction switching Error messaging Tolerance judgment output Various data output (RS-232C, BCD, segment) Peak measurement (maximum value, minimum value, runout) and arithmetic operation (addition, average, maximum value, minimum value, maximum width) between axes Applications With the appropriate Cartridge Head, the Mu-Checker can be used in a multitude of applications. With the 519-521 you can measure: The thickness of a rolled sheet material The maximum runout of a gear The pitch of HDD head components The pitch and runout of slitter blades With the 519-385 you can: Take a multipoint measurement on a VTR chassis Measure the concentricity and runout of a shaft Measure the height of a piston head
