Bently Nevada 177230-01-01-00 Seismic Transmitter

The 177230-01-01-00 (also cataloged as the 177230 Seismic Transmitter) measures casing vibration and outputs an RMS velocity signal. The 316L stainless steel body houses a piezoelectric sensing element and a 3-pin MIL-C-5015 connector for direct integration into machinery monitoring systems.

Seismic Signal Characteristics

The 177230 measures absolute casing vibration in RMS velocity, distinct from eddy-current proximity probe systems. The internal piezoelectric crystal generates a charge proportional to vibration, conditioned into a velocity output across 10 Hz to 1 kHz. The 3-pin MIL-C-5015 connector provides a shielded interface; the shield must be terminated at the monitoring end only to prevent ground loops. Gap voltage validation does not apply to this transmitter. The 316L stainless steel case and connector resist corrosion in humid or wash-down environments.

Frequently Asked Questions

Q: What is the mounting thread specification?
A: The unit uses a 1/4-28 UNF mounting hole. Ensure the stud or adapter engages the full thread depth for stable high-frequency response.

Q: Is the 177230-01-01-00 hot-swappable?
A: No. Disconnecting the 3-pin connector interrupts the signal and causes a fault reading. Place the monitoring channel in bypass before removal.

Q: Does the transmitter require external power?
A: No. It is a self-generating seismic transmitter. The piezoelectric element produces the signal without an external supply.

Field Installation Guidelines

Mount directly on the machine casing using the 1/4-28 UNF hole. Ensure flat metal-to-metal contact; remove paint, rust, or gaskets from the mounting face. Torque the stud to specification to maintain high-frequency response. Route the connector cable away from high-voltage conductors. Use shielded cable with the shield terminated only at the monitoring end. For hazardous area installation, verify the area classification matches the CSA/NRTL/C or ATEX/IECEx approval marking. Do not apply torque to the connector body; use the wrench flats on the case. Confirm signal integrity with a vibration analyzer before final connection.
