FAQ
Q1: What is the primary use of the 990 transmitter?
A1: It’s used for monitoring vibration in small machinery, transmitting a 4–20 mA signal to control systems.
Q2: Which probe is compatible with this transmitter?
A2: The 3300 NSv proximity probe and matching extension cable.
Q3: Can the transmitter be used in hazardous areas?
A3: Yes, it has CSA Division 2, ATEX Zone 0/2, and IECEx approvals.
Q4: What is the recommended power supply voltage?
A4: Between 12 and 35 VDC.
Q5: Does it support diagnostics?
A5: Yes, a dynamic “Prox Out” signal is available for diagnostic tools.
Q6: Is the output signal isolated?
A6: No, but the 122115-01 Test Adapter can provide signal isolation.
Q7: How is the probe gap set?
A7: Between 0.5 mm and 1.75 mm (20–55 mils) from the target.
Q8: What mounting options are available?
A8: DIN rail and bulkhead mounting clips are standard options.
Q9: Can this transmitter trend dynamic vibration?
A9: No, it only outputs peak-to-peak vibration via 4–20 mA signal.
Q10: Is this suitable for System 1 diagnostic integration?
A10: No, it is not designed for System 1 or other advanced diagnostics platforms.
