HEIDENHAIN-SPECTO ST 1200 and ST 3000
The solution for multipoint inspection apparatuses with station widths of only 15 mm
Multipoint measuring stations are becoming ever more important in production. Typical applications are the simultaneous detection of several measured values or combining single measuring steps during machining.
Length gauges from the HEIDENHAIN SPECTO series feature station widths of less than 15 mm, enabling several length gauges to be positioned in tight spaces. To keep space requirements in the system low, cables can be either axially or radially connected. The length gauge is also ideal for in-process measurements thanks to a protection class to IP67.
Accuracy of ±1 µm is ensured over measuring strokes of 12 mm (with the ST 1200) or 30 mm (with the ST 3000). The short-range accuracy (measurement error in a measuring range of 200 µm) is typically less than 0.3 µm, and repeatability has the same low value. These values are possible among other factors due to the highly precise ball guide, designed for a life of more than 60 million measuring cycles.
HEIDENHAIN offers a range of evaluation electronics for processing the measured values on multipoint inspection apparatuses:
- The ND 2100G GAGE-CHEK with up to eight measuring channels enables values to be displayed and directly evaluated. The scope of the software and hardware enables the saving of processes and responses and the display of PLC functionality with applications.
- The MSE 1000 is a modular evaluation unit with up to 250 measuring channels. In addition to channels for measured values, analog signals with ±10 V can also be imported for temperature sensors for example. Four floating inputs and outputs enable actions prior to, during and after measuring. The supply of pneumatic length gauges can also be switched on and off via a compressed air module.
- The EIB 740 with four measuring channels is an ideal evaluation unit for applications requiring high dynamic measured-value acquisition. The device enables data interrogation every 100 µs.
HEIDENHAIN SPECTO length gauges are therefore the ideal solution for multipoint inspection apparatuses. Combining them with the various evaluation electronics enables perfect configurations according to the specific application.
