Construction and Materials
The housing uses polycarbonate, which resists impact and electrical interference. Meanwhile, screw terminals accept standard field wiring without specialized tools. The compact footprint fits DIN rails, so retrofits require minimal cabinet space.
Interface and System Compatibility
This transmitter accepts signals from Bently Nevada velocity and acceleration transducers. Additionally, the 4–20 mA output interfaces directly with PLCs and DCS platforms. Therefore, users integrate vibration data into existing control systems easily.
Installation Guidelines
Mount the unit away from excessive heat and strong electromagnetic sources. Furthermore, route input and output wiring separately to reduce noise coupling. Correct grounding practice improves measurement stability, so follow plant standards carefully.
