Bently Nevada 990-04-70-01-00 2-Wire Vibration Transmitter – Industrial Machinery Sensor
Overview
Bently Nevada 990-04-70-01-00 Vibration Transmitter
The Bently Nevada 990-04-70-01-00 is part of the 990 series 2-Wire Vibration Transmitter line — a rugged, loop-powered device engineered to provide reliable vibration measurement for rotating industrial equipment such as compressors, pumps, motors, and fans. It accepts input from Bently Nevada 3300 NSv proximity probes and conditions the signal into a proportional 4–20 mA output suitable for PLC, DCS, SCADA, and machinery protection systems.
Designed for harsh industrial conditions, this transmitter supports easy mounting (DIN-rail or bulkhead), integrated zero/span adjustment, and reliable performance over a wide temperature range. Its 4–20 mA output is widely used for trend monitoring, vibration alarms, and feedback control in automated systems.
