GE 859‑B‑P0‑NN‑NN‑H‑N‑N‑C‑N‑N‑M‑B‑B‑F‑B‑1E‑C‑N‑B‑N‑043X transmitter

Product Description

Model: 859‑B‑P0‑NN‑NN‑H‑N‑N‑C‑N‑N‑M‑B‑B‑F‑B‑1E‑C‑N‑B‑N‑043X, GE 859 series integrated vibration transmitter (Bently Nevada, formerly GE Condition Monitoring). It integrates piezoelectric acceleration sensing and signal conversion unit, converts bearing housing vibration into standard 4~20mA analog output for local vibration monitoring. This full long part number is custom configuration. Built-in filter circuit, metal housing, high shock resistance and EMI immunity, compliant with API670 rotating machinery protection standard. It can be directly connected to PLC / DCS, widely used as field sensor spare part for turbine, fan and pump TSI condition monitoring systems.
