The Hengstler 225 series mechanical counter provides accurate recording for a wide variety of revolution, length measuring or stroke counting applications where continuous automated processes require a totalising readout.
Revolution and length counters are suited for continuous rotary movement and count bi-directionally. Stroke counters are for reciprocating motion within a limited degree of rotation; an internal spring returns the shaft to a start position, they accumulate a count value in one direction only.
The Hengstler 225 series revolution, length and stroke counter come with a large 6 digit resettable display and a 7mm diameter double output shaft.
There are two types of shaft rotation, either BZ or BW.
BZ shaft rotation, viewing the front display, the top of the rotary shaft is coming towards the observer.
BW shaft rotation, viewing the front display, the top of the rotary shaft is going away from the observer.
Choose between a stroke or revolution counter (999999) or a length measuring counter ( 99999.9 m/dm or 9999.9 m/cm). Transmission ratios are 1:1, 1:5, 1:10 or 1:50 depending upon the version selected.
A button, secured to prevent accidental operation, is used to reset the counter, unlock the reset button by pressing a red spring-loaded safety disc, then press the reset button down to reset the device.
A counter with a suspension device and an adjustable counterweight is used to regulate the pressure against moving material to ensure sufficient grip to prevent slipping.
Strike levers for the stroke counters, measuring wheels for revolution and length counters are purchased separately.
