FAQ
Frequently Asked Questions (FAQ)
Q1: What type of sensor does the 990-04-70-02-00 transmitter support?
A1: It supports the Bently Nevada 3300 NSv non-contact eddy current probe and extension cable (5 m or 7 m).
Q2: What is the output signal of this transmitter?
A2: It outputs a 4–20 mA DC signal proportional to the peak-to-peak vibration amplitude.
Q3: Does it feature fault detection?
A3: Yes, it drives the output below 3.6 mA upon detecting a fault, restoring it in 2–3 seconds.
Q4: Can it output dynamic signals for diagnostics?
A4: Yes, via the “PROX OUT” terminal, and it is recommended to use the 122115-01 test adapter for isolation.
Q5: Are zero and span adjustments possible?
A5: Yes, they are manually adjustable using onboard potentiometers.
Q6: What environments is it suitable for?
A6: Designed for industrial use in wide temperature and high humidity (100% condensing) environments, typically for compressors, fans, and small motors.
Q7: What are the mounting options?
A7: It supports both DIN rail mounting and bulkhead screw mounting options.
Q8: Is the product approved for hazardous areas?
A8: Yes, it has multiple approvals including ATEX Zone 0/2 and CSA Division 2 certifications.
