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.

As with all of our LVDT displacement transducer range customisation to suit your application is possible so please contact us if you would like to discuss the possibilities in your particular application.

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.
