Product Overview

E33NCHA‑LNN‑NS‑00 is a loop‑powered field‑mount vibration velocity transmitter for rotating‑machinery condition monitoring. It measures casing vibration of fans, pumps, motors and compressors and converts vibration velocity value into standard 4‑20 mA analog signal for PLC/DCS system acquisition. Robust IP67 metal housing adapts to harsh plant‑field environments; hazardous‑area certification allows installation in classified zones. Widely stocked as refurbished and new‑old‑stock spare parts for petrochemical‑plant rotating‑equipment‑monitoring‑system maintenance.

Application Notes

‑ Loop‑powered 24 V DC 4‑20 mA circuit; verify loop resistance during commissioning. ‑ Mount rigidly on machine casing to avoid measurement distortion. ‑ Follow hazardous‑area installation rules for explosive‑atmosphere applications. ‑ Typical deployment: refineries, power‑plants, chemical‑plants for pump, fan, compressor condition‑monitoring spare‑part stocking.
