Gauge block calibration system
The EPP 01 Gauge Block Calibration System can not only yield faster, more accurate results (+/-10nm) but also lower to ~15 the number of gauge blocks needed to calibrate a 122 block set.
Calibrating gauge blocks can be a time-consuming and expensive process However, using the EPP 01 Gauge Block Calibration System from SIOS Messtechnik (available in the UK from Armstrong Optical ) can not only yield faster, more accurate results (+/-10nm) but also lower to ~15 the number of gauge blocks needed to calibrate a 122 block set

Low cost thermal imaging sensor module
Armstrong Optical of Northampton is able to offer the IR106 infrared sensor module at a price that will make it the sensor of choice for 3rd-party thermal imaging system builders.
The EPP 01 Gauge Block Calibration System utilises a new metrological method in which the upper inductive probe normally used in such calibration systems is replaced by an LM 20 series laser-interferometric gauging probe with a measuring range of 20mm and a resolution of 1nm.
In addition a proprietary calibration technique allows system linearity errors (errors due to misalignment, probe tilt and thermal effects) to be determined and compensated for.
The system is operated from a PC running "Parallel Gauge Block Calibration" (PEKAL) signal processing and control software.
The software controls the motion (raising/lowering) of both gauging probes whilst simultaneously obtaining temperature and pressure data allowing for compensation for temperature and pressure drift during measurement.
As well as the normal calibration routines, the EPP 01 compensates for errors, computes centre sizes, recognises nominal sizes, outputs departures of centre sizes from nominal sizes and classifies gauge blocks by their degree of accuracy.
All the test data and results can then be output in custom-designed test reports.
Typical applications include the calibration of plane-parallel gauge blocks with rectangular cross-sections ranging in size from 0.5 to 100mm, measuring characteristic dimensional parameters in compliance with DIN 861, factory/field calibrations of metrological instrumentation and the calibration of unusual types of nominal sizes and items fabricated from non-standard materials.
