The ‘Industrial’ series of LVDT’s are a rugged displacement/position sensor designed for the most arduous of applications. The body diameter increases to Ø22.2mm for added strength over the standard series of LVDT’s and available stroke ranges remain, with 0-1mm being the smallest and 0-1000mm being the largest. IP65, IP68 submersible and 150ºC high temperature versions are available.
The AML/IE series industrial LVDT is available with AC mv/V or DC/DC output signals. DC/DC is the most commonly used, as the signal conditioner is built into the LVDT body giving a self-contained sensor. Outputs available are +/-2.5Vdc, 0-5Vdc, 0-10Vdc and 4-20mA, all are 3-wire format. If a shorter bodied LVDT is required a compact in-line DC in/DC out signal conditioner is available (see gallery image above) which can provide a 0-5Vdc, 0-10Vdc or 4-20mA output signal.
The industrial LVDT range offers two levels of environmental sealing; IP65 (provided as standard) which will give water and dust protection in industrial applications, and an optional IP68 waterproof version which provides complete protection against water ingress in both partially and fully submerged applications.
For high temperature measurements above +70ºC, a high temperature version of the LVDT is offered rated to +150ºC. This version cannot have a signal conditioner fitted internally and so it is mounted in-line on the LVDT’s cable and must be located where temperatures will not exceed +70ºC.
Our industrial displacement transducer is available in 3 different mechanical configurations:
- Spring Loaded Core & Extension Rod with Ball-Tip (±100mm max range) - Suited to applications where the piece to be measured can’t always be in contact with the LVDT plunger, or where physical attachment of the LVDT plunger to the test piece is not possible.
- Guided Core & Extension Rod - Suited to applications where attachment to the measuring point is required, but the measuring point cannot support the weight of the core and extension, or where it cannot provide ideal axial guidance.
- Rod-End Bearings (with Guided Core) - Ideal for cylinder measurement applications and situations where fixing the sensor at either end is preferred to clamping the LVDT body.
As with all our LVDT type position sensors, the sensing principle is contactless which makes it an extremely robust, long-lived sensor. We can also provide customisation to suit your application so please contact us if you would like to discuss the possibilities in your particular application.
