990 Vibration Transmitter

Description

The 990 Vibration Transmitter is intended primarily for the original equipment

manufacturers (OEMs) of centrifugal air compressors or small pumps 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, loop-powered device that

accepts input from our 3300 NSv

TM

proximity probe and its matching extension

cable (available in 5m and 7m system length options). The transmitter conditions

the signal into appropriate peak-to-peak vibration amplitude engineering units,

and provides this value as a proportional 4 to 20 mA industry-standard signal as

the input to the control system where machinery protection alarming and logic

occurs

.

The unit provides the following notable features:

Specifications

Unless otherwi noted, the following specifications

apply at +22°C (+72°F) using a 3300 NSv Probe and

Extension Cable, and an AISI 4140 steel target.

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

conds after the NOT OK

condition is removed.

Power-up

Inhibit:

Signal output stays at less than

3.6 mA for 2 to 3 conds after

power is applied.

Proximitor

Sensor Output:

Compatible with ungrounded,

portable test equipment. When

using grounded, ac-powered test

equipment, u the 122115-01

Application Advisory

The pha of the PROX OUT signal is inverted from the standard

for Bently Nevada LLC products. Also, connecting grounded ac-

powered equipment to PROX OUT may result in a fal alarm.

U test adapter 122115-01 to connect ac equipment to the

transmitter. Note that the 122115-01 also inverts the PROX OUT

signal.
