This year, Solartron Metrology made a series of investments in an effort to be part of the many ‘green initiatives’ which are taking place within industries across the globe


This replacement of an older system ensured our calibration rooms could maintain the required humidity levels in the face of ever changing external climates.
It has helped to ensure accurate calibration of our digital probes and transducers, saving energy in the process.


In October 2021, we installed two new air compressors which are critical to the operation of many of our high performance CNC turning and honing machines.
These compressors will ensure that we continue to manufacture high performance and reliable sensors for many years to come.
They include state of the art controllers and automatically adjust and shut down, depending on air demand, thus saving energy and contributing to sustainability and helping the environment.
Alongside the new compressors we also invested in new air filtration units.



Solartron Metrology offers DZ sensors - shortest on the market - 1mm and 2mm gauging probes

Short body sensors with high accuracy and good repeatability are perfect solution for checking certain dimensions in automotive and aerospace parts may require multiple points, but in spaces where standard gauging probes would be too tall to fit into. Examples might be checking multiple inner diameters of a transmission housing, or perhaps taper measurements.



Earlier this month, we mentioned that it's been 75 years since Solartron Metrology first began life as Farol Research back in 1946. But did you know it’s also been:

  • 50 years since we developed our first precision analogue probe


  • 25 years since our first digital probe was created

As gauging developed over time, there came the need for even greater accuracy and performance - that's why our first digital probe was developed in 1996 to give enhanced LVDT performance and the ability to work straight out of the box with no set up required.

Today, Solartron Metrology probes are used all over the world in a wide range of applications. This includes iphone components, car parts, positioning telescope mirrors, monitoring construction projects, medical and automotive industries.

Our products are special and unique because all of our sensors can be customised for specific customer applications.

Displacement SM transducers


Solartron Metrology SM transducers are designed for measuring displacement in applications where infinite resolution and repeatability are required in very small size.

Manufacturers producing mechanical testing instruments and welding machines must gather data to measure physical displacement. Solartron Metrology’s products are suitable for this type of application due to their rugged construction and high accuracy.

Hardness testers are used to measure the density of hard alloy, carbon steel, alloy steel and non-ferrous metals. Compact dimensions of sensors were needed for easy when incorporating the sensors into the machines.

SM probes were used to measure the physical displacement of the tool tip as it produces an indentation in the surface of the item under test. Data from the SM probe and the force sensor is then used by the CPU to calculate the hardness of the material under test. The calculated hardness reading is then displayed on the testing machine’s integrated read-out.



Very common packaging across different manufacturing areas are zip lock plastic bags. The quality of the plastic zip lock is highly important as for food packaging as well as for screws storing. Solartron Metrology offers standard DP range of Digital Spring Push Probes as a solution to control the plastic bag zip lock quality during manufacturing.

The position and measurements of a zipper on a plastic bag needs to be taken in-process as the material is dispensed from a roll and prior to the cutting and heat-sealing progress. The range of Solartron standard DP proves ensures very high resolution, excellent linearity and high data speed, long life precision bearings, and an IP65 rating ensure that probes maintain their performance of millions of cycles. Digital probes with a SI7500 readout connected to a PLC allow to identify and resolve issue on the line before large quantity of products were produced, reducing waste and down-time.

    Turbine mount

    Solartron Metrology offers high precision digital sensors to meet aerospace supplier needs in gauge mount. In the aerospace industry, an engine component such as a turbine blade is often cast, and then machined to the proper dimensions, via a CNC.  To check specifications after the initial setup, the operator removes the blade from the CNC, then has it checked by a CMM in a Quality Lab.  Depending on the workload for the CMM, the operator can wait for hours or in some cases a day to perform a check. This is costly, as the blades cannot be re-machined until the specifications are verified.

    Solartron digital probes helps to do quicker throughput, lower labor cost and data collection with Orbit Network.

    A Solartron digital probe is built for tough environments, with a stainless-steel casing, high precision bearings, and excellent sideload strength. Each probe is calibrated throughout its mechanical range in our State of the Art factory.

    Extreme elements

    Solartron Metrology offers LVDT probes of any extreme environments. Testing or monitoring of infrastructure components could mean that materials are subjected to extreme elements, such as heat, cold, salt water, wind, or other types of stress. To monitor how these perform, linear measurement transducers must be able to endure the same conditions, all while continuing to monitor and measure the slightest shift or crack in a material.


    Linear variable differential transformers (LVDTs) and other metrology tools have many applications in agriculture and play an important role in a wide range of functions that are critical to the various sectors in this industry.

    The measurement and monitoring of climate, land and soil, the optimisation of farming practices and the assurance of worker safety are all integral to agricultural industry performance, and LVDT technology and the data that it produces are vital to the provision of this knowledge and functionality. 

    Precision-measurement sensors are used in many agricultural industry applications, providing key data that allow companies and organisations to achieve key performance, responsibility and efficiency goals. 

    Orbit® Network

    Solartron’s Orbit® Network can be used to connect multiple sensors together to check complex shapes, such as a knee prosthesis. For checking the knee joint pictured here, three Gauging probes were used to check a top surface, while a flowmeter was used to check the diameter and angle of a critical hole in the base of the joint.  All readings can be synchronized and output to an SPC software pack via the Orbit® Network.  

    Height Checking Needles and Sharp Edges

    For medical manufacturers, precisely measuring the height of a needle or a sharp edge is often critical to product quality and function.

    However, accurately measuring the height of a needle or a sharp edge can be problematic. Non-contact sensors, such as 2D or imaging sensors, find it difficult to identify the absolute tip of a needle or sharp edge. This deficiency can have a potentially negative impact on product quality and performance.

    Solartron Metrology offer an accurate, low-cost solution – Feather Touch and Ultra-Feather Touch probes.

    Solartron Metrology Feather touch and Ultra-feather touch probes provide clear advantages over other technologies. These highly precise, repeatable measurement sensors have low-tip forces down to 0.05N that can measure delicate surfaces with sub-micron accuracy in some cases. They are easy to set up and integrate with existing systems and offer higher repeatability and less sensitivity to the environments in which they are used.

    The advantages of Feather touch and Ultra-feather touch probes can be further optimized when used with theSolartron Orbit3® Digital Measurement System. The system is a digital, modular network built for easy data collection and analysis via a PC, PLC or existing in-house network.
