Potted housing resists 100% humidity environments
Frequently Asked Questions (FAQ)
Q1: What type of sensor is compatible with the 990 transmitter?
A1: It works with the 3300 NSv proximity probe and extension cable.
Q2: What output signal does it provide?
A2: A 4 to 20 mA current signal proportional to peak-to-peak vibration.
Q3: Can the transmitter operate in hazardous areas?
A3: Yes, with ATEX and CSA approvals for Zone 0, Zone 2, and Division 2.
Q4: What mounting options are available?
A4: DIN rail clips, bulkhead screws, or both.
Q5: How does the Not OK condition affect output?
A5: It drives the output below 3.6 mA within 100 µs to signal fault conditions.
Q6: Is the PROX OUT signal isolated?
A6: No. Use the 122115-01 Test Adapter for safe diagnostic connections.
Q7: What is the purpose of the Test Input pin?
A7: It allows for verification of the 4–20 mA output with a function generator.
Q8: Can it be used for dynamic vibration analysis?
A8: Limited. It is intended for trending, not full diagnostics.
Q9: What’s the typical frequency range for monitoring?
A9: 5 Hz to 6,000 Hz.
Q10: Does it support real-time gap voltage and vibration monitoring?
A10: Yes, through the PROX OUT port for dynamic diagnostics.
