K-TEK M4A-AT-2017 Magnetostrictive Level Transmitter

Product Description

The M4A-AT-2017 is a K-TEK (now ABB) AT series magnetostrictive level transmitter head assembly. It works with the magnetostrictive probe to measure liquid level and interface level inside tanks. It converts the position signal of the magnetic float into standard 4–20mA analog output, and can support HART digital communication. This M4A is the electronic transmitter housing variant for AT100/AT200 level instruments, widely used for liquid inventory control in oil & gas, chemical and refinery tank farms. The suffix 2017 stands for specific probe length, process connection and material configuration of the full unit.
