Bently Nevada 990-04-70-01-05 combines a 7 m proximity-transducer system with a 0–4 mils peak-to-peak vibration range. Integrated signal conditioning supplies a proportional 4–20 mA control-loop output, while DIN-rail clips support panel installation.
Description
Bently Nevada 990-04-70-01-05 is a 990 series vibration transmitter configured for a 0–4 mils peak-to-peak range and a 7 m transducer system. Its two-wire circuit delivers a 4–20 mA machinery-control signal. DIN rail clips and the specified multiple-approval option define this ordering configuration. An integrated Proximitor sensor conditions the connected proximity probe signal. Dynamic output supports diagnostic measurements with suitable isolated test equipment. The transmitter suits centrifugal air compressors and smaller rotating machinery requiring overall vibration trending.
Function
The integrated signal conditioner converts proximity-probe input into a proportional vibration-amplitude signal for machinery-control systems.
A Not OK circuit suppresses misleading high outputs caused by probe faults or loose connections.
Product Applications
Centrifugal air compressor OEMs can incorporate overall vibration trending into their machinery-control arrangement.
Small pumps, motors and fans can use the transmitter where a simple proportional monitoring input is required.
