Submersible LVDT Transducers in stock at ADM

power supply submerged in water

ADM is proud to have stock of RDP Electronic’s DCW series of submersible LVDT linear position transducers.

RDP DCW Series Submersible LVDT Transducer

Using the standard connector arrangement of the DCW LVDT transducer, an IP68 (10 bar) rating is achieved once the connector is fitted.

This makes the DCW series perfect for any application where it could be splashed by or become submersed in non-corrosive fluids.

One recent example we have is in a mining application on the tail end of a machine shaft.  The IP integrity is required because of the high humidity environment and presence of high volumes of coal dust

Other possible applications include:

  • Provision of position feedback
    • aeroplane control surfaces, robot arm, joy-stick, hydraulic actuator, assembly line mechanicals
  • Valve position
    • water/sewerage industry, throttle control, marine hatches and plumbing
  • Structural movement
    • underwater installations, bridges, buildings, cranes

Non-magnetic fluids can flood the armature tube without affecting the operation of the transducer.

Being a Linear Variable Differential Transformer (LVDT) type transducer means that they are probably the most robust and reliable linear position sensor type available.

The big advantage of the LVDT sensor's principle is that there is no electrical contact across the transducer position sensing element, which gives you clean data, infinite resolution and a very long life. They are ideal for any application, where repeated and rapid movement needs to be monitored.

The actual model ADM has in stock is model number DCW2000B.

This is a captive guided model, with a measuring range of +/- 50mm.  Captive guidance means the transducer has bearings to guide the armature inside the measurement sensor. Captive LVDTs are for position measurement applications where external guidance of the armature is poor, or difficult to achieve.

The DCW2000B has an analogue voltage output of -5V ~+5V, which is commonly used on mobile equipment applications.
