For over 40 years, Eley Metrology has been at the centre of the design and manufacture of high-quality metrology products and precision measurement equipment.
We offer an impressive range of height gauges, from basic vernier models to the Vertex VMS, which provides a unique solution in the field of Digital Height Gauges.
Supported by a UKAS Certificate of Calibration, the Vertex VMS is the most advanced digital height gauge available on the market today.
What is a Height Gauge
As the name suggests, it is a device for measuring the height of an object. Their roots can be traced back to 1631 when Pierre Vernier, a French scientist and mathematician, invented the "Vernier scale". This allowed mechanical engineers to measure and manufacture with much greater precision than ever before. Vernier's system of dissimilar scales was the founding of precision measurement, and nearly 400 years later, we still use Vernier's principles.
Height gauges are typically used in conjunction with granite surface plates or tables. Granite surfaces are a must for accurate measurement as they provide a flat and stable surface for inspection.
There are a number of both mechanical and digital height gauges available on the market. Which you decide to use will depend on your budget and measuring needs.
Vernier Height Gauge
This type of height gauge is available in sizes from 6 inches to 6 feet in height. Relatively simple to operate, their main advantage over other height gauges is the range of sizes they come in, meaning they can be used to measure a wide range of workpieces accurately. Typically, two scales are shown on the beam of the height gauge. The main scale is engraved in millimetres (in the case of a metric scale). Also shown is the Vernier scale, which can read to an accuracy of 0.01 mm.
Digital Height Gauges
Digital height gauges can be split into three distinct groups.
The first group are relatively basic and have accuracy levels similar to those of the mechanical height gauge described above. They will typically use an inch/metric scale along with floating and absolute zero.
The middle group of digital height gauges is effectively an upgrade on the first. They share all the features of the first group but have several additional settings, such as ID/OD measurement and probe compensation. Height gauges within this group will have far greater accuracy than those in the first.
The final group offer another big step up in accuracy as well as a host of additional features. You can expect a computer interface, air bearings, motorised probing operation and 1D and 2D measurement capability. The Vertex VMS digital height gauge is a great example of how advanced devices in this group have become.
If you'd like to know more about our height gauges and how they can be used to support your business, then the team at Eley Metrology are here to help. Our Vertex VMS is supported by a UKAS Certificate of Calibration and is available in three different sizes allowing us to cater for a range of different industries and requirements.
