Gap Voltage Validation (-10 VDC Targets) & Eddy-Current Probe Scaling

The transmitter processes high-frequency RF excitation signals from a 3300 XL proximity probe across a 10 to 65 mils displacement range. Correct physical installation requires gap voltage validation to confirm the probe tip maintains a static bias voltage of -10 VDC at the physical center of its linear operating span. Precise eddy-current probe scaling ensures accurate transduction of peak-to-peak shaft displacement into a proportional 4-20 mA analog output without signal attenuation or phase delay.

Frequently Asked Questions

Q: How is the transmitter powered across the analog output circuit?

A: The module utilizes a 2-wire loop-powered architecture operating on a nominal 24 VDC loop power supply, drawing operational current directly through the 4-20 mA measurement loop.

Q: What input sensors are compatible with this transmitter model?

A: The transmitter accepts direct input connections from Bently Nevada 3300 XL proximity probes combined with matching extension cables in 5 m, 7 m, or 9 m total system lengths.

Q: Can the device be mounted on standard control cabinet rails?

A: Yes, the 03 suffix option integrates pre-installed mounting hardware designed for snap-on attachment to 35 mm DIN rail networks.

Field Installation Guidelines

Mount the transmitter housing onto a grounded 35 mm DIN rail inside an enclosure, ensuring adequate clearance for field cable strain relief.
Connect the 3300 XL proximity probe extension cable coaxial connector to the transmitter input jack, tightening the connection finger-tight.
Adjust the mechanical probe position relative to the target shaft until reaching the required -10 VDC gap voltage target across the raw probe test terminals.
Route 2-wire twisted-pair shielded cable from the 4-20 mA loop connections to the control system analog input cards.
Terminate the cable shield at a single ground point on the cabinet rack earthing bus bar to suppress electromagnetic interference and loop noise.
