Frequently Asked Questions (FAQ)
Q1: What type of probe is required for this transmitter?
A1: It is compatible with Bently Nevada 3300 NSv proximity probes and extension cables.
Q2: Can it operate in hazardous environments?
A2: Yes, it meets CSA Division 2, ATEX Zone 0/2, and IECEx approvals.
Q3: What does the Not OK/Signal Defeat function do?
A3: It reduces the signal to <3.6 mA during probe faults or disconnections to avoid false alarms.
Q4: Is the output signal isolated?
A4: The “PROX OUT” signal is not isolated. Use the recommended 122115-01 test adapter for diagnostics.
Q5: How is it mounted?
A5: It supports both DIN rail and bulkhead screw mounting options.
Q6: What is the linear range of measurement?
A6: The linear range for Prox Out is 0.25–1.65 mm.
Q7: Does it support real-time diagnostics?
A7: Yes, via the PROX OUT signal output connected to test equipment.
Q8: What power voltage does it require?
A8: It operates on +12 to +35 VDC loop power.
Q9: Is it suitable for continuous monitoring systems?
A9: No, it is intended for trending and protection; continuous monitoring systems offer broader functionality.
Q10: What environments is it designed for?
A10: It is suitable for high humidity (up to 100% condensing) and industrial temperature extremes.
