Filter by mechanical package

Gagehead type

Gagehead LVDT transducers are also known as pen-probes, displacement probes or measurement probes.

These models have a guided plunder that is supported by linear ball bearings or simple sleeve, and are extended by spring or pneumatic force. They are widely used due to their durability, use simplicity and high repeatability.

Open-core type

LVDT Unguided

Open-core LVDT transducers are also known as unguided LVDT or dual part LVDT sensors.

The use of open-core LVDTs require that both body and core are guided by a mechanical fixture. Their applications are usually suitable on measurement fixtures and offer an excellent cost-benefit.

Captive-core type

Captive-core LVDT transducers are also known as core-guided LVDTs.

Captive-core models have the benefits of open-core models added to a convenient sleeve supports, simplifying the application and keeping core alignment during sensor movement.

Filter by signal output

AC Output

LVDT transducers with AC output have the basic construction with only the primary and secondary winding inside.

Typical application requires excitation of the primary winding with an AC signal and processing of the phase and output of the secondary winding. These models are usually associated with LVDT signal conditioners or measurement equipments with compatible input channels.

DC Output

LVDT DC

LVDT transducers with DC signal output have embedded electronics responsible for powering and process the sensor internal signals, converting the detected displacement into a stable DC voltage signal.

These transducers typically require a DC power supply (symmetrical or asymmetrical, based on model requirements) and output a stable DC signal that can be directly connected to signal acquisition boards, displays with analog inputs or any compatible equipment.

4-20mA Output

LVDT transducers with 4-20mA current loop output have embedded electronics responsible for powering and process the sensor internal signals, converting the detected displacement into a current output.

These transducers typically require a DC power supply connect to the current loop and the output current varying from 4 to 20mA based on the detected displacement. Transducers with 4-20mA output are suitable for applications that require long cable length or use inside explosive atmosphere environment.

RS-485/Orbit Output

LVDT RS485

LVDT transducers with RS-485 interface have embedded electronics capable of powering, processing and digitalizing the sensor internal signal, making it available for transmission over a RS-485 network Standard MSI and Orbit compatible protocol supported.

The RS-485 network allow simple connection of multiple nodes, long length cables, high noise immunity and easy setup for visualization and data acquisition for SPC.

USB Output

LVDT transducers with USB interface have embedded electronics capable of powering, processing and digitalizing the sensor internal signal, making it available for transmission over a USB on industrial computers, personal computers or notebooks.

Multiple modules can be connected on a same USB port with use of USB HUBs.
