As well as adjustment measurements, the GEPARD™ M4 with the new cylindrical casing can now take absolute measurements for the first time and is thus especially suitable for use in rotatory systems. In this area therefore, the rotation, run-out or alignment of gears, shafts or drives can also be measured and regulated. For greater robustness and better temperature coefficients, the standard cylindrical casings are made of stainless steel (INOX) but are also available in aluminium as an option.
GEPARD Transmitter S4R cylindrical
The new cylindrical GEPARD laser transmitter is distinguished by the high-precision align-ment of its optical-mechanical longitudinal axis. This alignment allows precise absolute measurements in relation to the laser focal point for example, the alignment of rotation systems or the machining axes of milling cutters, lathes, boring machines etc.
Using suitable mountings, the cylindrical transmitter is also suitable for measurement and alignment work on flat test objects.
GEPARD™ Receiver E4R (cylindrical)
In addition to the features of the E4K, the cylindrical receiver also has high-precision alignment of the optical-mechanical longitudinal axis, which, together with the matching transmitter (S4K), permits absolute measurements to be performed.
Like the E4K, the GEPARD E4R transmits its measurement data wirelessly via Bluetooth to the evaluation PC. Because of its infra-red operation and the powerful NiMH rechargeable batteries, the receiver is completely wireless and is trouble-free in use.
