AMS EZ 1000 Eddy Current Measurement Chain

With Emerson´s AMS EZ 1000 eddy current sensor and converter you always have the part you need when you need it.

With one converter that is compatible with a range of sensors and cables, you’ll be able to mix-and-match your spares to your application while reducing your converter inventory. And with an easy-to-use procedure for field calibrations, you’ll be back to work sooner. The AMS EZ 1000 makes changing out sensors following a shutdown or replacing sensors during turnarounds/maintenance quick and painless.
