Description of Vibration Transmitter

The 990 Vibration Transmitter is intended primarily for the original equipment manufacturers (OEMs) of centrifugal air compressors or small pumps, motors, or fans who prefer to provide a simple 4 to 20 mA proportional vibration signal as the input to their machinery control system. The transmitter is a 2-wire, looppowered device that accepts input from our 3300 NSv* proximity probe and its matching extension cable (available in 5 m and 7 m system length options).

Specification of Vibration Transmitter

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.
Zero and Span	Non-interacting external adjustments.
NOT OK/Signal Defeat	Signal output will go to less than 3.6 mA within 100 µs after a Not OK condition occurs. Signal output is restored within 2-3 seconds after the Not OK condition is removed.
Power-up Inhibit	Signal output stays at less than 3.6 mA (NOT O.K.) for 2 to 3 seconds after power is applied. The purpose is to signal that the device is not yet ready. Transients may be observed when device goes O.K.
Proximitor Sensor Output	Compatible with ungrounded, portable test equipment. When using grounded, ac-powered test equipment, use the 122115-01 Test Adapter for signal isolation.
Output Impedance	Prox Out has a 10 kW output impedance calibrated for a 10 M load.
Prox Out Linear Range	1.4 mm (55 mils). Begins at approximately 0.25 mm (10 mils) from target surface.
Prox Out Incremental Scale Factor	7.87 mV/µm (200 mV/mil) ± 6.5% typical including interchangeability errors when measured in increments of 0.25 mm (10 mils) over the linear range using a flat 30 mm (1.2 inch) target. Worst case 7.87 mV/µm ± 10%. Typical Noise Level: 50 mV/pp.
Temperature Stability	Incremental scale factor remains within ±10% of 7.87 mV/µm (200 mV/mil) from 0 C to +70 C (+32 F to +158 F).
