K-Tek M4A-AT Magnetostrictive Liquid Level Transmitter Electronic Module

Product Description

M4A‑AT is an electronics transmitter module for K‑TEK (ABB) AT100 / AT200 magnetostrictive level transmitters. It supports single‑level measurement, integrated with LCD local display and push‑button configuration. Loop‑powered with 4‑20 mA analog output and HART communication, SIL‑2 certified. It converts magnetic float position signal into standard industrial signal for DCS / PLC system. On‑site calibration can be completed without opening housing. Mainly used for level instrument maintenance replacement and spare‑part stock. It is a core electronics component for process instruments, some versions are legacy end‑of‑life spare parts.

Technical Parameters

Product Application

1. Instrument maintenance replacement: Replace faulty electronics head for AT100/AT200 level transmitters to restore level measurement.
2. Tank continuous level monitoring: High‑precision continuous level measurement for tanks and reactors in petrochemical, chemical and oil‑gas industries.
3. DCS system integration: 4‑20 mA + HART signal connects to DCS/PLC for remote level monitoring, parameter setup and device diagnosis.
4. Hazardous area deployment: Matched with explosion‑proof housing for tank measurement in classified chemical zones.
5. On‑site spare‑parts inventory: Preventive spare stock for process plants to reduce instrument‑related downtime.
