Supply 990-16-XX-01-CN BENTLY NEVADA Vibration Transmitter Wholesale Factory

Electrical
Input	Accepts 1 non-contacting 3300 NSv Proximity Probe and extension cable.
Power	Requires +12 to +35 Vdc input at the transmitter terminal.
4 to 20 mA Signal Output	4 to 20 mAdc over specified full-scale range in 2-wire configuration.
4 to 20 mA Loop Accuracy	Within ±1.5% over specified full-scale range. Accuracy is rated from the TEST signal input to the voltage measured across a 250 loop resistance.
Probe Gap	Probe must be gapped between 0.5 and 1.75 mm (20 and 55 mils) from target to ensure full scale range.
Maximum Loop Resistance	1,000 including cable at 35 Vdc.
Current Limiting	23 mA typical.
Environmental Limits
Operating Temperature:	-35 °C to +85 °C (-31 °F to +185 °F)
Storage Temperature:	-51 °C to +100 °C (-60 °F to +212 °F).

The 990 Vibration Transmitter is designed for OEMs of centrifugal air compressors, small pumps, motors, and fans. It delivers a 4 to 20 mA proportional vibration signal to machinery control systems. This 2-wire, loop-powered device connects to the 3300 NSv proximity probe and matching extension cables (available in 5 m and 7 m lengths). It conditions the input signal into peak-to-peak vibration amplitude units and outputs a standardized 4 to 20 mA signal for effective machinery protection and alarming logic.
Integrated Proximitor* Sensor requires no external unit
Non-isolated “PROX OUT" and "COM" terminals plus a coaxial connector to provide a dynamic vibration and gap voltage signal output for diagnostics2.
Non-interacting zero and span potentiometers under the Transmitter label supports loop adjustment.
Test Input pin for quick verification of loop signal output, using a function generator as the input.
A Not OK/Signal Defeat circuit prevents high outputs or false alarms due to a faulty proximity probe or loose connection.
