What is a Linear Transducer?

A Linear Transducer is a type of position sensor. They form part of our product portfolio here at Variohm.

Linear transducers measure linear displacement or movement along a single axis in any direction. They do this by converting the movement into an electrical signal which is proportional to the displacement so that it can be processed by various devices.  

Linear Transducers are available in different types, each type is better suited to a different application or environment. Some linear transducers have different certifications making them well suited to hazardous areas or intrinsically safe applications. They are also available in various sizes to suit long-range applications or applications where space is restricted.

Types of Linear Transducer

The different types of linear transducers we have available are;

Potentiometer – we offer our range of potentiometers which are a type of linear transducer. They use an internal resistive track and wipers to monitor the position of an object.

Positek PIPS – our sister company Positek use their technology known as PIPS within their linear transducers. This is a non-contacting technology for wear-free operation.

LVDT – another non-contact type of linear transducer, these are similar to Positek sensors.

Cable Extension Transducer – an alternative solution for linear displacement, a cable extension transducer uses a flexible cable. These have a greater stroke-to-length ratio making them well suited to long-range applications.

Other Types of Transducer

At Variohm we have a selection of various transducers for different types of measurement. Some of these include;

Pressure Transducers – for accurate measurement of actual pressure

Temperature Transducer – for temperature measurement

Rotary position transducers – to measure position in a rotary fashion
