HEIDENHAIN-CERTO Length Gauges

Accuracy ± 0.1 μm

Accuracy: 0.1 μm; Recommended Resolution: 0.005 μm;

Measuring Length: 60mm; Plunger Actuation: Motor

The total error of HEIDENHAIN-CERTO length gauges lies within ± 0.1 μm. After linear length error compensation in the evaluation electronics of the ND 28x, for example, HEIDENHAIN guarantees accuracy of ± 0.03 μm for the CT 2500 and ± 0.05 μm for the CT 6000. These accuracy grades apply over the entire measuring range at ambient temperatures between 19 °C and 21 °C and with a temperature variation of ± 0.1 K during measurements using the CS 200 gauge stand for HEIDENHAIN-CERTO.

Accuracy
HEIDENHAIN-CERTO length gauges feature a large measuring range, provide high linear accuracy and offer resolution in the nanometer range. They are used predominantly for production quality control of high-precision parts and for the monitoring and calibration of reference standards. Length gauges reduce the number of working standards required to calibrate gauge blocks.

HEIDENHAIN-METRO Length Gauges

Accuracy ± 0.2 m

MT 1287 Accuracy: 0.2 μm; Recommended Resolution: 0.05 μm;

Measuring Length: 12mm; Plunger Actuation: Spring Force Down

With their high system accuracy and small signal period, the HEIDENHAIN-METRO MT 1200 and MT 2500 length gauges are ideal for precision measuring stations and testing equipment. They feature ball-bush guided plungers and therefore permit high radial forces.

Plunger actuation
The length gauges of the MT 12x1 and MT 25x1 series feature a spring-tensioned plunger that is extended at rest. In a special version without spring it exercises particularly low force on the measured object
In the pneumatic length gauges MT 1287 and MT 2587, the plunger is retracted to its rest position by the integral spring. It is extended to the measuring position by the application ofcompressed air.

Mounting
The MT 1200 and MT 2500 length gauges are fastened by their 8h6 standard clamping shank. A mounting bracket is available as an accessory to mount the length gauges to plane surfaces or to the MS 200 from HEIDENHAIN.

HEIDENHAIN-METRO Length Gauges

Accuracy ± 0.5 μm

MT 60 Accuracy: 0.5 μm; Recommended Resolution: 0.1 μm;

Measuring Length: 60mm; Plunger Actuation: Motor

Large measuring ranges together with their high accuracy make the MT 60 and MT 101 HEIDENHAIN-METRO length gauges attractive for incoming inspection, production monitoring, quality control, or anywhere parts with very different dimensions are measured. But they are also easy to mount as highly accurate position encoders, for example on sliding devices or X-Y tables.

Plunger actuation M version length gauges feature an integral motor that retracts and extends the plunger. While the MT 101 M operates at a constant gauging force, the MT 60 M allows you to select from three gauging force levels.K version gauges have no integral plunger actuation. The plunger is freely movable. It can be connected to moving elements such as linear slides and X-Y table by a coupling.

Mounting
The length gauges are mounted onto a fl at surface by two screws. HEIDENHAIN offers the M versions for mounting in the accessory MS 100 and MS 200 gauge stands.

HEIDENHAIN-SPECTO Length Gauges

Accuracy ± 1 μm

Thanks to their very small dimensions, the HEIDENHAIN-SPECTO length gauges are the product of choice for multipoint inspection apparatus and testing equipment.

Plunger actuation
The length gauges of the ST 12x8 and ST 30x8 series feature a spring-tensioned plunger that is extended at rest. In the pneumatic length gauges ST 12x7 and ST 30x7 the plunger is retracted to its rest position by the integral spring. It is extended to the measuring position by the application of compressed air.

Mounting
The HEIDENHAIN-SPECTO length gauges are fastened by their 8h6 standard clamping shank.
