LVDT Sensor | Low Tip Force Inductive Sensors

Solartron Metrology contact gauging probes, LVDT probes or displacement sensors provide the gauge builder with the most cost effective solution for a range of dimensional precision measurement and positioning applications.

The Ultra Feather Touch displacement probe has so light a tip force, it is a viable alternative to a non-contact sensor in many applications. With various tips available in ruby and nylon, the UFT displacement transducer is already being used to check glass, rubber, semi-conductor wafers and other delicate materials.

Buy your LVDT sensor from Solartron Metrology and be sure that you are getting an LVDT sensor that is a result of 40 years continual improvement from our experienced design engineers, manufactured solely in our dedicated ISO9001 accredited factory in the UK. 

Standard Digital Displacement Sensors | Gauge Probes

The Vacuum retract displacement probes (gauge probes) offer an alternative means of controlling the contact sensor tip using a vacuum rather than a positive pneumatic pressure. In all other ways they perform the same as pneumatic displacement sensors (gauge probes) and like all the digital gauge probes have advantages other traditional LVDT sensors.
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.

Solartron Metrology contact digital gauging probes or displacement sensors provide the gauge builder with the most cost-effective solution for a range of dimensional precision measurement and positioning applications.

The digital gauge probe combines the strong features of a conventional linear variable differential transformer (LVDT) with enhanced accuracy. The accuracy specified for the digital sensor is total accuracy unlike conventional LVDTs which specify linearity. Another benefit of the digital displacement sensor (Gauge probe) is the probe requires no set up or adjustment with conditioning electronics like a traditional LVDT because the digital displacement sensor provides a precision measurement straight out of the box. 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.

Like a conventional LVDT the displacement probe tip is pushed out using an internal spring. The precision bearings inside the digital displacement senor ensure precise positioning of the contact senor tip. At the same time the unique bearing design provides repeatable measurements even when the displacement transducer is subjected to mechanical side loads. 

Attention to detail in both design and manufacture of the displacement sensor ensures precision measurement throughout the linear displacement transducer's life.

A pneumatic displacement sensor (gauge probe) allows the number of parts in the fixture to be reduced resulting in improved reliability and reduced fixture cost. It also allows for fast automatic loading of the part into the gauge as the displacement probe tip can be in the fully ‘retract position’ when this is occurring.

The benefit of using a pneumatic push displacement sensor (gauge probe) compared to a spring push probe is that there is less need to design mechanisms to bring the contact senor tip onto the part being measured thus simplifying the overall gauge design.

One issue with pneumatic push displacement probes is that the air inflates the probe gaiter to push the contact sensor tip onto the part being measured. If the gaiter becomes damaged it may not inflate and therefore the probe cannot operate. The Pneumatic Piston Push (Jet) probe uses an internal piston so will continue to operate even if the gaiter is damaged. Air is bled out from a small hole near the front of the contact sensor to allow for retraction therefore the sealing (IP50) may not be suitable for all applications.

The pneumatic piston push displacement probes (gauge probes) like all the digital gauge probes have advantages over traditional LVDT sensors.

Designed for oily and wet gauging applications, the new IP 68 sealed probes from Solartron Metrology are sealed at all points of ingress and offer improved sealing compared with IP 67 or IP 65 sensors.

Solartron  IP 68 sealed probes are also rigorously tested for a 100% seal before being delivered to customers - a commitment to quality standards and performance that helps Solartron rise above the competition.

With the sealing verified by a third party, there is no loss of performance with the IP 68 sealed probes, with up to 0.05% full-scale accuracy, 0.15µm repeatability and 0.01µm resolution.

High-quality gaiters

The protective gaiters supplied with the IP 68 sealed probes conform to the highest quality standards.

The gaiter material, fluoroelastomer, has a high temperature tolerance and chemical resistance rating. It has a synthetic rubber that resists many hydrocarbons, biodiesel and petrochemicals. However, it is not compatible with ketones.

Please note that the gaiter on the IP 68 sealed probes cannot be replaced in the field. If the gaiter is torn, the probe should be returned to Solartron for repair. Get all the technical specifications of the IP 68 sealed probes

Full sealing available for most gauging sensors

The IP 68 sealing is available for most standard Orbit® Digital Measuring Spring and Pneumatic Probes. It is available on TTL , as well as on the 12mm diameter Rugged Gauging Sensors. IP 68 is also standard on Solartron DUSM probes, which are excellent for bore gauging and low profile applications.

More information on the compatibility of IP 68 sealing can be found in our IP 68 sealed probes datasheet
