LinTran™ Inductive Linear Encoders

Non-contact, inductive linear encoders for accurate and reliable linear position sensing in harsh environments.

lintran Linear position sensor

Robust Linear Position Encoders for Extreme Environments

Zettlex LinTran inductive linear encoders are non-contact absolute linear position measuring devices that utilize a unique inductive technique. Each linear encoder is comprised of two main components – a Target and a Stator. The Stator is longer than the Target, is powered with an electrical supply and can be moving or stationary.

The electrical output from the Stator shows the position of the Target relative to the Stator. The target has no electrical connections and can be moving or stationary

LinTran Inductive Linear Encoder

High-reliability Inductive Linear Encoder Technology

Zettlex LinTran encoders are sealed to IP67 and are ideally suited to harsh environments where electrical contacts or optical transducers would prove unreliable. The LinTran linear encoder range offers a cost effective alternative to LVDTs, magnetostrictive devices or precision potentiometers. LinTran inductive linear position encoders have wide mounting tolerances and are field-programmable without a PC.

Practically, the materials, from which the sensor’s main components are produced, limit the operating and storage temperatures.

Importantly, the sensor’s fundamental operating principles are not affected by temperature. That means Zettlex sensors can operate in relatively low or high temperatures.

Most frequently, the effective temperature range is limited by the electronic components at –40 to 85 or 125 Celsius (i.e. industrial or automotive ranges).

However, it should be noted that the sensor’s electronics can be displaced away from the Antenna. This enables the sensors to be designed such that only the Antenna and Target are placed in harsh temperature environments whilst the Electronics are placed in a more benign environment away from, or insulated from, the harsh conditions.

Ceramic substrates for the Antennae and Target substrates can be used to increase temperature limits.

We have built sensors that can withstand constant operation at +230 Celsius and we are developing sensors for +450 Celsius.

We have built sensors to operate in -55 and -60Celsius.
