Description
The AML/M series of miniature LVDT displacement transducers are available in ranges from ±0.25mm (0-0.5mm) up to ±50mm (0-100mm).
Available in either a 4-wire or 6-wire configurations, the miniature LVDT requires a sinusoidal AC supply voltage and provides an AC mV/V output signal which is linearly proportional to displacement.
A compact in-line DC in/DC out signal conditioner is available to complement the miniature LVDT and provide a 0-5Vdc, 0-10Vdc or 4-20mA output signal if required.
The miniature LVDT is available in one of 3 mechanical configurations; plain core-only, plain core & extension rod and spring loaded core and extension rod.
Their small size and variety of mechanical configurations make the AML/M miniature LVDT suitable for a broad range of applications such as material testing machines, production and development test rigs, quality assurance testing, automotive and aerospace actuators and within pressure sensors.

Note: On DC output version (0Vdc / 4mA) is given with the core in the extended / outwards position. This can be reversed if
required, please request Option Y on your order. |
| **The spring-loaded version is only available with a radial cable exit due to the rear extension of the LVDT. |
Note: On versions with in-line signal conditioner zero output (0Vdc / 4mA) is given with the core in the extended / outwards
position. This can be reversed if required, please request Option Y on your order. |
