Question 1

What makes the Slimline AC LVDT different from the Standard AS Series?

Accepted Answer

Body diameter — 9.5mm or 12.7mm versus 22mm for the AS Series. The AM is designed for space-constrained fixtures, automated gauging heads, and OEM equipment where the standard 22mm body cannot physically fit.

Question 2

What ranges does the Series AM cover?

Accepted Answer

11 standard models from ±1mm to ±60mm (2mm to 120mm total stroke). Models 001AM–030AM use the 9.5mm diameter body; models 040AM–060AM use the 12.7mm body for the longer stroke variants.

Question 3

What excitation does the AM Series require?

Accepted Answer

2V rms at 2 kHz sinusoidal, supplied by an external signal conditioner. The AM Series is compatible with all standard AC signal conditioners.

Question 4

Can the Slimline LVDT replace a mechanical dial gauge?

Accepted Answer

Yes. The compact body and short starting length (44mm for the 001AM) make it a direct electronic replacement for mechanical dial gauges in automated gauging heads and production-line inspection fixtures — providing infinite operating life, frictionless operation, and digital data capture.

Question 5

Is a spring return available on the AM Series?

Accepted Answer

Yes. Spring return (suffix R) is available for models 001AM through 015AM, providing positive core rod retraction in applications where the test object cannot push the core back.

Question 6

What cable options are available?

Accepted Answer

Standard 3m PVC shielded cable. Optional cable lengths up to 15m are available for installations where the sensor is far from the signal conditioner.

Question 7

Is the AM Series suitable for OEM integration?

Accepted Answer

Yes. The 9.5mm and 12.7mm body diameters are among the smallest LVDT sizes commercially available, making the AM Series the preferred choice for OEM machine builders embedding sensors directly into compact assemblies.

Question 8

Does the Slimline LVDT include calibration?

Accepted Answer

Yes. Every AM Series sensor ships with NABL-accredited factory calibration traceable to national standards, with a 3-year warranty.
