Single Leaf flexures & Mini probes
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.
Combining multiple sensors using the Orbit Digital Measurement network is easy and data can be read using a Solartron readout or the Gauge Computer Software making system integration simple.
Attention to detail in both design and manufacture of the displacement sensor ensures precision measurement throughout the linear displacement transducer's life.
Solartron Metrology offers a large range of displacement sensors to suit multiple applications with different cable outlets (radial or axial), multiple measuring ranges, different cable types like steel braided which provides additional protection for displacement sensors that are being used in harsh environments.

Digital Displacement Sensor - DR
Solartron's well proven and popular S Series displacement transducers have provided the ideal platform for the SR ruggedized transducers, specifically developed for challenging environments in Lab & Test, and Process Control applications. Environmental ratings for the SR Series have been increased to IP 68 or Hermetically Sealed, both with higher temperature capability where required on AC and Digital versions. Screw Mount options allow easier installation where the use of conventional mounting clamps are a problem, and a strong modular construction with sturdy end caps and guides ensure a long and reliable life in harsh conditions.
