Special Transducer

Product Description

Special Transducers are available for application where the standard pencil style probe will not fit.

Block Gauges – DK

Solartron’s Block Gauges makes precision measurements of bores and cavities a simple and reliable process. More generally, the use of these devices is recommended in applications where space and access are limited and where the use of axial probes is not possible. The 2 mm Block Gauge is only 8 mm wide. The Block Gauges offer unrivaled ruggedness, accuracy, and repeatability. All three units are extremely versatile and provide datum surfaces and all the adjustments required for precision gauging applications. Block Gauges have robust precision linear bearings with minimal clearance, which limits unmeasured movements maintaining good repeatability even when the contact tip is mounted off center.

Parallel Flexure

Parallel Flexures with high resolution and excellent repeatability make Solartron’s Flexure Transducers the first choice for high-speed precision gauging. With no sliding moving parts, the flexure will maintain performance for millions of cycles and are virtually free from hysteresis. Flexures can be mounted such that there is little or no stress through the gauge line enabling precision profiling of moving materials such as rotating shafts, brake discs, etc. With resolution better than 0.05 µm at speeds up to 3906 readings per second, the flexure with Orbit® provides an excellent dynamic solution.

With the same advantages as the parallel flexure, the single leaf flexure offers the gauge builder access to even more measurement points. With careful use of extension arms measurements can be made inside slots or between features where a conventional pencil probe cannot reach.

DUSM – Mini Flexure

DUSM – Mini Flexure

  • 5 mm measuring range
  • Resolution better than 0.01 µm
  • Repeatability better than 0.5 µm
  • Spring actuation
  • IP68 sealing
  • Extension arms
  • Robust design in a compact package

The Miniature Single Leaf Flexure is another variant of flexure based contact probes. The miniature single leaf flexure has a calibrated range of 0 – 500 microns and provides the means for alternative configurations of contact tip mounting. The gauge body mounting to the fixture is accomplished using a single M2.5 screw. Contact tip mounting is attached by using either the integral M3 locking thread insert, primarily intended for use with length extensions, OEM’s fixed-length contact tips or with Solartron’s tip adapter, which when applied with Solartron’s dedicated tip allows for 1 mm of height adjustment. OEM tips may be fitted to either option, but it is advised that the height be limited to a maximum of 6 mm above the gauge top surface, to avoid significantly prejudicing gauge life and repeatability. The mid adjustment range is the reference point for the calibration using the standard tip. Length extensions may be applied to this style of gauge but should be used with care. A maximum length of 12 mm, between the tip and mounting thread, is advised, but this does depend on other variables such as tip height approach angle and measurement deflection – extremes of these conditions will significantly reduce the gauge life and severely degrade the repeatability. To enable direct reading of the gauge using extensions, the use of a software multiplier will be necessary. However, as the reference dimension for the gauge is 18 mm by using a 12 mm extension, a range of 833 microns is achieved but a reading of only 500 microns is observed.

DM –Mini Probe

DM –Mini Probe

  • 5 or 1 mm measuring range
  • Accuracy better than 0.1 µm
  • Resolution better than 0.01 µm
  • Repeatability better than 0.5 µm
  • Spring actuation
  • IP65 sealing

The Mini Probe is a compact, low profile transducer that is ideal for measurement in confined spaces, such as bores. The transducer is based on a parallel spring structure that ensures excellent repeatability over a long working life, even when rotated in bores that have key slots or lubrication ports. A Tungsten Carbide contact tip is fitted as standard but a selection of customer-replaceable tips with an M2 thread is available for special applications. Repeatability depends on the alignment of the mini probe whether on-axis or cross-axis as shown in the diagram.

DL –Lever Probe

DL –Lever Probe

  • 5 mm measuring range
  • Accuracy better than 3 µm
  • Resolution better than 0.01 µm
  • Repeatability better than 0.5 µm
  • Spring actuation

Solartron’s Digital Lever Probe has been conceived for the precision measurement market. The probe is ideally suited to applications where the use of axial measuring probes is not possible, and where a low tip force and a high number of probing points are required. It’s a simple design and exceptional reliability result in a reduced cost of ownership without any reduction in performance. Due to its cylindrical housing geometry, the Lever Probe can be mounted in any attitude relative to the intended target, although the stylus motion must be normal to the intended measurement.

Linear Encoder

The Digital Linear Encoder range of gauges consists of high accuracy optical probes designed for use in applications where consistent submicron measurement accuracy is required. In contrast to traditional inductive gauging probes, the accuracy is maintained along with the entire measurement range. The LE is ideal for laboratory and test applications but for industrial applications, a Solartron digital probe is often a better choice offering a more robust solution.
