The 990-04-XX-01-00 MOD 147202-01 provides reliable vibration monitoring for rotating machinery.
This unit connects to one 3300 NSv non-contacting proximity probe and extension cable.
It converts vibration signals into a 4 to 20 mA analog signal for easy system integration.
The transmitter operates on a wide voltage range to fit different industrial power systems.
It offers two system length options for flexible on-site installation and wiring.
CSA Division 2 approval allows deployment in non-hazardous and Div 2 hazardous areas.
External zero and span controls make field calibration simple and efficient.
The device quickly detects faults and drops its output signal to a safe level within 100 µs.
The 990-04-XX-01-00 ensures stable performance in pumps, motors, and critical turbomachinery.
The 990-04-XX-01-00 MOD 147202-01 has a full-scale range of 0–4 mils pp (0–100 μm pp).
System length is available as 5.0 meters (XX=50) or 7.0 meters (XX=70).
It carries CSA Division 2 approval for safe use in designated hazardous areas.
No additional agency approvals are included in this standard configuration.
The unit accepts one 3300 NSv non-contacting proximity probe and extension cable.
Input power requirement is +12 Vdc to +35 Vdc at the transmitter terminal.
It provides a 2-wire 4 to 20 mAdc output over the full measurement range.
Loop accuracy is within ±1.5% of full scale across normal operating conditions.
Probe gap must be set between 0.5 mm and 1.75 mm from the target surface.
Maximum loop resistance is 1,000 Ω including cable at 35 Vdc supply voltage.
Typical current limiting for the module is set at 23 mA for circuit protection.
Zero and span adjustments are external and non-interacting for easy setup.
In a Not OK condition, output falls below 3.6 mA within 100 microseconds.
The signal returns to normal within 2 to 3 seconds after the fault clears.
Frequency response spans 5 Hz to 6,000 Hz with a +0, –3 dB tolerance.
Minimum required target diameter is 9.5 mm for reliable measurement.
Maximum BNC leadwire length for proximitor output is limited to 3 meters.
The unit is approved for non-hazardous, Zone 2, and Division 2 hazardous areas.
A 28 Vdc power supply is recommended for hazardous location operation.
Total weight of the transmitter is 0.43 kg for compact panel mounting.
Mount the 990-04-XX-01-00 MOD 147202-01 near the equipment being monitored.
Choose either 5-meter or 7-meter system length based on cable routing needs.
Install the 3300 NSv probe with a gap of 0.5 to 1.75 mm from the target.
Connect the probe and extension cable to the transmitter input securely.
Wire the 2-wire 4–20 mA loop to your controller or monitoring system.
Apply +12 to +35 Vdc power to the transmitter terminals properly.
Use external controls to adjust zero and span for your measurement range.
Ensure total loop resistance does not exceed 1,000 Ω at 35 Vdc.
Keep BNC output cables shorter than 3 meters to maintain signal quality.
Confirm installation meets CSA Division 2 standards for hazardous areas.
Power on the system and verify normal and fault response behavior.
Use a target of at least 9.5 mm diameter for accurate vibration reading.
