Bently Nevada 140482-01 Tachometer module

Description

Signal:

Each Tachometer Module accepts up to two

transducer signals from proximity probe

transducers or magnetic pickups. The input

signal range is +10.0 V to -24.0 V. Signals

exceeding this range are limited internally by

the module.

Input Impedance:

20 kΩ (standard); 40 kΩ (TMR); 7.15 kΩ

(Internal Barrier)

Power:

Typical consumption of 5.8 watts

OUTPUTS

OK LED:

Indicates when the 3500/50 is operating

properly.

TX/RX LED:

Indicates when the 3500/50 is communicating

with other modules in the 3500 rack.

Bypass LED:

Indicates when the 3500/50 is in Bypass

Mode.

Buffered Transducer

Outputs:

The front of each module has one coaxial

connector for each channel buffered output.

Each connector is short circuit and ESD

protected. Buffered outputs are also

available on the I/O Module via Euro Style

connectors. The following specifications

assume a load impedance of 100 KOhms +/-

1%.

Output Impedance: 550 Ω

DC Offset: 35 mV maximum.

DC or AC Gain: 0.98 to 1.01

Transducer Supply Values:

-21.5 to -24.7 Vdc, 40 mA maximum per

channel

Recorder:

+4 to +20 mA. Values are proportional to

module full-scale range (rpm or rpm/min).

Individual recorder values are provided for

each channel. Operation is unaffected by

short circuits on recorder outputs.

Voltage Compliance

(current output):

0 to +12 Vdc range across load. Load

resistance is 0 to 600 Ω.

Resolution:

0.3662 µA per bit, ±0.25 % error at room

temperature, ±0.70 % error over temperature

range. Update rate approximately 100 ms.

SIGNAL CONDITIONING

Specified at +25° C (77° F)

Speed Input:

The 3500 Tachometer will support 0.0039 to

255 events per revolution with a maximum

full-scale range of 99,999 rpm and a

maximum input frequency of 20 kHz.

Minimum input frequency for proximity

transducers is 0.0167 Hz (1 rpm for 1

event/revolution) and for passive magnetic

pickups is 3.3 Hz.

RPM Accuracy:

RPM/MIN Accuracy:

Less than 100 rpm = ±0.1 rpm

100 to 10,000 rpm = ±1 rpm

10,000 to 99,999 rpm = ±0.01 % of the true

shaft speed

±20 rpm/min

TRANSDUCER CONDITIONING

Auto Threshold:

Manual Threshold:

Hysteresis:

Use for any input above 0.0167 Hz (1 rpm for

1 event/revolution). Minimum signal

amplitude for triggering is 1 volt peak to peak.

User selectable from +9.5 to -23.5 Vdc.

Minimum signal amplitude for triggering is

500 millivolts peak to peak.

User selectable from 0.2 to 2.5 volts.
