Variohm Eurosensor offers cable extension transducer featuring a polycarbonate body
Variohm Eurosensor
SG1 series cable extension transducer
Celesco’s SG1 series cable extension transducer — available from Variohm Eurosensor — is suitable for demanding measurement applications ranging from hydraulic cylinder positioning to structural testing and medical equipment position feedback.
The SG1 is designed to build on the design characteristics of the SP and SM series short-range ‘stringpot’ sensors by offering a longer 2m measurement range in a compact 75 x 75 x 50mm polycarbonate housing with optional IP67 protection.
The low-cost transducer is targeted at end users requiring fast off-the-shelf delivery and original equipment manufacturers needing larger quantities.
The SG1 — which offers an accuracy of 0.35 per cent and repeatability to 0.05 per cent full scale — provides absolute linear position measurement over a 2m full-stroke range with a voltage divider output from a 10kΩ plastic-hybrid potentiometer and a recommended 30VDC supply.
Key features and benefits
- The rugged polycarbonate body houses a precision high-cycle plastic hybrid potentiometer in a spring-loaded cable drum arrangement with a stainless steel measuring cable in a free-release design that helps guard against damage if the cable is accidentally released.
- A choice of three electrical interfacing options covers use for normal and more extreme environments.
- Direct connection to the potentiometer solder terminals ensures IP50 protection.
- There are IP67-rated options for a 1m strain-relief cable and an M12 connector with an O-ring seal for wet-environment protection — supplied with a mating cable if required.
- The SG1 has three through-hole mounting points directly in its housing and is also supplied with a steel mounting bracket that offers four 90° opposed mounting orientations as well as front- and back-face fixing.
