Cable Extension Transducers

We are an authorised UK distributor of Celesco Cable Extension Transducers. We are also able to offer a safety-rated range of cable extension transducers from our sister company Control products Inc. (CPI)

Cable Extension Transducers have different names;

• Cable Extension Transducers
• String Pots
• Draw Wire Sensors
• Cable Actuated Position Sensors

All of these terms describe a type of position sensor which measures and detects linear position and velocity through the use of a flexible cable (or wire) and a spring loaded spool.

All of the cable extension transducers that we offer can be seen above, they are from our supplier Celesco who have now become part of TE Connectivity.

Our range of CPI Cable extension transducers are completely ATEX and IECEx certified making them suitable for intrinsically safe environments. They are suitable for subsea applications as well as surface deployments with stroke lengths up to 10m. 

The SL2000-6000 series of sensors from CPI enables hydraulic system designers to now have access to a harsh duty line of linear position sensors which are unique in the industry.

The SL2000-6000 products combine two proven technologies into a sensor system that has full intrinsic safety ratings for both the Americas and Europe: 

Celesco Plastic Housed Cable Extension Transducers we have available are the SM,SP,SG and SR series. They are an in-stock range from TE Connectivity and are very popular among our customers. They are suitable for a vast range of applications and are compact, economical and easy to install, they can be adjusted for ease of mounting.  

The heavy duty industrial cable extension transducer range offers reliable performance in harsh environments and is well suited for use in factories, on mobile equipment and managing water. They have measurement ranges from 1.9m to 14m and a wide variety of options, within this family there is also an extended option. These can measure up to 43m but are only 150mm in height. They are suitable for both indoor and outdoor applications and can be installed quickly and easily by mounting the body to a fixed surface and then attaching the cable to the movable article. 

The Light Industrial Cable Extension Transducers are for indoor industrial applications. This range offers a wide variety of either analogue or digital signal outputs. Digital outputs can include DeviceNet®, Incremental Encoder and RS232. The Analogue output options include Voltage Divider, 4...20 mA (2- and 3- wire), 0...10 Vdc (also 0-5 Vdc, ±5 Vdc and ±10 Vdc).  Critical alignment is not required for the light industrial cable extension transducer range; this means that the device can be installed quickly.

These are compact cable extension transducers which are highly accurate and easy to use. The PX150 is particularly well suited to motion control of precision machinery, for example, medical scanning devices for CT and MRI machines. The PTX101 has a potentiometric output and measurement ranges to 2,500mm.

The Celesco range of Cable Extension Transducers for Test and Automation have been proven on structural test applications. They have excellent linearity and ultra-smooth mechanisms so they can give reliable and high resolution measurements.

These are miniature cable extension transducers for high performance, they are easy to install and have been designed specifically for space restricted applications. They are able to be mounted on irregularly shaped structures and can follow motions to 136 G’s. Possible applications for the test and motorsport cable extension transducers are; crash test deflection, structural tests and monitoring vehicle suspensions.
