The transducer uses the latest generation of AMETEK’s field-proven magnetostrictive position-sensing technology to give absolute analogue position, accurate to 0.04% of the programmable sensing distance. A variety of analogue outputs are available to meet user needs.
The rugged, rod style LDT fits entirely inside a hydraulic or clevis style cylinder. This protects the transducer from outside conditions and allows use where there is no room for external devices.
It can be powered from 8-30VDC at 1.6W, making it easy to fit into a variety of systems. It includes a built-in diagnostics capability that displays the health of the unit and helps aid in troubleshooting problems if they occur.
The 958A is easy to install and set up. Units can be ordered in span lengths from 50-2540mm (2-100”) and come standard with either integral cable assemblies, bare leads or M12 style connectors.
