ABOUT US

For over sixty years Yorkshire Precision Gauges has specialized in the design and manufacture of high quality precision gauges – a vital element and a secure basis for inspection procedures. With a proud history and a great team of people YPG continue to be the “Go To” name in precision inspection gauges.

Today, as accuracy standards become increasingly important, we offer a range of standard, made to-order Go & No-Go Gauges, Indicating Precision Bore Gauges, B2 Digital Gap & Step Gauges and Thread Measuring Systems.

Quality is assured. Our metrology laboratory is UKAS approved and our Quality Management System is certified to BS EN ISO 9001:2015 by BSI. Go & No-Go gauges comply with British Standards, although we produce to other national and international standards as required by our customers and work to tolerances to less than 0.001mm.

Service is paramount at YPG and we support customers ranging from small workshops to some of the world’s largest multi-nationals.

Express Manufacture Service. Modern manufacturing is a matter of tight deadlines and cost constraints. On-time delivery is a watchword at YPG, knowing a missed gauge delivery promise can disproportionably impact a customer’s production. For that reason, YPG offers an EXPRESS manufacturing service on our range of Reversible Plug Gauges that will cater for the last-minute customer realisation that a gauge is required.

Go & No-Go FIXED LIMIT GAUGES

For many years Go & No-Go Fixed Limit Gauges have been a vital part of maintaining tolerances of the highest standard and have been at the core of quality control applications for a variety of end-user applications. Fixed Limit Gauges provide an accurate, quick, easy to use and economical solution of the inspection of work pieces, giving a pass (Go) or fail (No-Go) result.

Go & No-Go REVERSIBLE PLUG GAUGES

Why Reversible?

YPG Reversible Gauges can have up to twice the useful life compared to non-reversible types because most of the wear in use occurs as the gauge is presented to a hole. With reversible gauges, the gauging member can simply be removed from its handle, reversed and refitted presenting a fresh, unworn gauge end.

How to specify your plug gauge requirements.

For plain plug gauge requirements (i.e. to check a single diameter) you only have to specify the hole size and work piece tolerance. From this information we calculate the required gauge tolerances according to a standard appropriate to you. In the UK, gauge tolerances are normally required in accordance with BS969: 1982. This British standard specifies the tolerances and limits for cylindrical plain plug, ring and gap gauges. Gauges can however be manufactured to any recognized national standard (DIN, NFE, AGD, TDS, ISO, JIS, ANSI/ASME).

For deep bores it may be necessary to specify also the protrusion required (i.e. the working length of gauge protruding from the handle).

For gauge sizes up to 19.45mm (No Go end) Wire Type Reversible gauges will be provided. Larger sizes will be supplied as Trilock Reversible gauges, unless the Taperlock design is requested.

Optional Pin & Plug Gauge Features.

Pin, Tri-Lock and Taper-lock gauges have a number of features which can be added to suit a particular application. YPG’s experienced, specialist gauge makers have considerable experience in applying these features against the customer’s component drawing requirements.

Fine Tolerance Additions.

If the work piece tolerance is a very tight manufacturing tolerance when standards such as BS 969:1982 are applied an additional charge will be incurred. If the work piece tolerance is tighter than 0.009mm, we would recommend

an Indicating Bore gauge be used.

B2 GAP & STEP GAUGES

The B2 Gauges are a unique range of digital rivet, gap & step gauges, for the inspection of assembly criteria in finished products. Widely used in the automotive, aerospace and railway industries.

B-Squared gauges are designed by experienced users of digital measuring equipment resulting in an ergonomic, compact product giving consistent, long term, measuring accuracy and repeatability.


OSIMESS SPLIT BALL BORE GAUGE

This Split Ball Bore Gauge from SCHWENK is an internal two-point precision bore gauge for the rapid and accurate measurement of small bores ranging from 1mm to 20mm. Individual Probes are available throughout this range with measuring spans between 0.2 and 1.3mm depending on size.

With OSIMESS it is not only possible to detect deviations from the nominal diameter, but also deviations in shape within the bore to be measured,

A complete measuring instrument comprises a measuring probe, a tungsten carbide measuring needle and a handle which can accommodate the required output method. Setting rings and indicators are sold separately.


This, the original SCHWENK Cylinder Bore Gauge is a universal and rugged two-point contact comparator gauge for the measurement of bores in the range of 4.5mm up to 800mm. The SUBITO range is available in standard (SU) and special designs to cater for unusual requirements including extra deep bores (up to 12m), right angle measurement, internal gears and splines, spherical diameters, internal grooves and blind bores.

Each SUBITO gauge incorporates the patented high-precision deviation element called the “segment”. This is the core piece of the SUBITO and ensures a transmission free of backlash of the contact pin travel to the connecting rod in the tube of the gauge and therefore on the measuring value indication. This element allows an individual adjustment of each gauge, so that excellent values for repeatability and the maximum deviation can be ensured. A complete SUBITO set would compromise of a holder, with the corresponding measuring pins and increment washers as well as the necessary wrenches. Provided in a wooden box. Setting rings and indicators are sold separately.

The SCHWENK Indicating Bore gauge is a robust, intelligent plug gauge with a mechanical two-point contact comparator, where each gauge is tailored to suit a specific application. The measurement application range is from 2.5mm to 800mm. The standard measuring range of an individual measuring sleeve is 0.2mm and hence the actual size to be measured must be specified together with its tolerance.

Output resolution depends upon the choice of output which may be mechanical dial or digital indicator. As with all comparative measuring methods, a suitable setting ring should be used. The standard design measuring sleeve is available to cover internal diameters up to 130mm. Above this size, and to minimize the weight of the gauge, a cross sleeve design is employed.

This OD series provides the highest level of accuracy and repeatability but is diameter specific. For all variants, deep bore extensions, blind bore and hard chrome plated versions are available.
