FAQs
Q1: What type of sensor is compatible with the 990 transmitter?
A: The 990 transmitter is designed to work with the Bently Nevada 3300 NSv proximity probe system.
Q2: Can the transmitter be mounted on a DIN rail?
A: Yes, it supports DIN rail or bulkhead mounting.
Q3: Does it provide diagnostic signal output?
A: Yes, a non-isolated PROX OUT BNC is provided for diagnostics.
Q4: Is the output isolated?
A: The PROX OUT signal is not isolated; use the 122115-01 Test Adapter for safe diagnostics.
Q5: What is the primary use case?
A: OEMs use it for simple vibration monitoring in compressors, pumps, and motors.
Q6: What environmental conditions can it handle?
A: It supports up to 100% condensing humidity and operates from -35°C to +85°C.
Q7: What happens during a probe fault?
A: The signal drops below 3.6 mA to indicate a “Not OK” condition.
Q8: Can it be used for phase analysis?
A: No, it provides only vibration amplitude—not phase information.
Q9: How do you test the 4–20 mA loop?
A: A test input pin is available for signal verification using a function generator.
Q10: What kind of approval does it have for hazardous areas?
A: It holds ATEX Zone 0/2 and CSA Div 2 hazardous location approvals.
