LVDT – Displacement Measurement Trainer
Product Code : EL-MAILE-10809
LVDT – Displacement Measurement Trainer (code EL-MAILE-10809) is a trainer in which a linear variable differential transformer (LVDT) measures small linear displacements, read in millimetres on a digital indicator. A micrometer jig on the base plate moves the LVDT core over the ±10.0 mm (0–20 mm) range, and the 3½ digit indicator reads up to ±1999 counts, with zero and calibration both set by front-panel potentiometers.

What Is the LVDT – Displacement Measurement Trainer Used For?
An LVDT has a primary coil fed with an alternating voltage and two secondary coils either side of it; moving the iron core away from the centre raises the voltage in one secondary and lowers it in the other, and the difference gives the size and direction of the movement. Students advance the micrometer in steps, note each setting against the indicator reading and plot the two to check the LVDT's linearity across its ±10.0 mm range. Zero and calibration are set from front-panel potentiometers so that the display agrees with the micrometer.
What to Specify When Ordering
- Quantity — the number of trainers required.
- Power supply — the 50 Hz or the 60 Hz, 230 V single-phase version.
Frequently Asked Questions
What is the measuring range of the LVDT?
The LVDT covers ±10.0 mm, which is 0 to 20 mm of total core travel, and the indicator reads up to ±1999 counts.
How is a known displacement applied?
A 0–25 mm micrometer mounted in a jig on the base plate pushes the LVDT core, so each displacement is set on the micrometer before being compared with the indicator reading.
How does an LVDT work?
A primary coil is energised with an alternating voltage and two secondary coils pick up a share of it. Moving the core changes the two secondary voltages, and their difference shows how far and in which direction the core has moved.
What excitation and connection does the LVDT use?
The LVDT is excited at 2000 Hz and connected to the indicator through a 6-core shielded cable fitted with a DIN connector.
How are zero and calibration set?
The front panel carries one potentiometer for zero adjustment and another for calibration, so the indicator reading can be matched to the micrometer setting.
How large is the trainer and what supply does it need?
It measures 400 × 300 × 300 mm, weighs approx. 15 kg and runs on 230 V single phase at either 50 Hz or 60 Hz.
