Description
The Bently Nevada 990-04-50-02-00 vibration transmitter is an industrial-grade vibration monitoring core device developed by Bently specifically for original equipment manufacturers (OEMs). Its core applications include centrifugal air compressors, small water pumps, motors, and fans. The product utilizes a two-wire loop-powered design, efficiently integrating power delivery and signal transmission functions, significantly reducing wiring complexity and installation costs. Featuring a full-scale option (04), it accurately captures vibration data within the range of 0-4 mils pp (0-100 μm pp). It also offers a system length option (50), supporting a signal transmission distance of 5.0 meters (16.4 feet), flexibly adapting to the monitoring layout needs of equipment of varying sizes.

Regarding installation and electrical performance, the transmitter uses a mounting option (02), supporting bulkhead screw mounting, and is also compatible with DIN rail clamp mounting as a standard option, flexibly adapting to the installation needs of different industrial sites and simplifying the installation process. The institutional certification option is 00 (Not Required), with no mandatory certification requirements, making it widely adaptable to various general industrial scenarios. Electrically, it requires a +12 to +35 Vdc DC power supply at the transmitter terminals. The maximum loop resistance (including cable) reaches 1000 Ω with a 35 Vdc power supply, ensuring the stability and reliability of signal transmission and adapting to the complex electrical environments of industrial sites.

This product features precise signal conditioning and reliable safety protection: it can condition received vibration signals to peak-to-peak vibration amplitude engineering units and output a 4-20mA industrial standard proportional signal, seamlessly integrating into mechanical equipment control systems to provide precise input for equipment protection alarms and logic control. The built-in NOT OK/signal failure circuit effectively prevents high output or false alarms caused by proximity probe malfunction or loose connections, ensuring the safe operation of the control system. As a dedicated accessory, it can directly receive input signals from a 3300 NSv proximity probe and its matching extension cable (5-meter and 7-meter system lengths are optional). With its stable performance and convenient installation design, it is an ideal choice for OEMs to improve equipment monitoring reliability and optimize control systems.
