Operating Principle and Signal Interpretation
The moving coil responds to relative motion between the coil and magnet assembly. This motion generates an AC voltage related to vibration velocity. Monitoring equipment can use the signal to assess casing vibration, provided the transducer sensitivity and the receiving instrument’s input requirements match.
The transducer’s stated passive operating principle means it generates its measurement signal without an external excitation supply. This differs from powered sensors that require an electrical supply to operate their sensing circuitry.
Mounting and Connector Configuration
The supplied configuration matrix describes a circular base with a 1/4-28 UNF mounting stud and a side-mounted two-pin connector housing. These details help identify the mechanical mounting arrangement and connector orientation when checking an existing installation or sourcing a replacement.
Confirm the connector interface, cable termination, mounting geometry, and instrument input requirements against the installed unit before replacement. The supplied information does not establish a specific compatible cable, monitoring channel, or replacement model.
Configuration Identification
The supplied suffix matrix lists the following configuration details for the complete order number. These descriptions should be treated as provisional until verified against the manufacturer’s ordering documentation.
| Option Code | Field Designation | Supplied Description |
|---|---|---|
| 10 | Mounting Angle / Sensitivity | 0 deg to 180 deg mounting orientation; 4.5 Hz (270 CPM) minimum operating frequency; 100 mV/mm/s sensitivity stated in the suffix matrix |
| 02 | Mounting Base | Circular base with 1/4-28 UNF mounting stud |
| 01 | Connector Mounting | Side-mounted MIL-C-5015 two-pin connector housing |
Frequently Asked Questions
Q: Does the 16699-10-02-01 require an external power supply?
A: The supplied description identifies a passive moving-coil design that generates an AC output from mechanical motion. Confirm the receiving monitor’s input and termination requirements before installation.
Q: What should be checked when replacing this transducer?
A: Verify the full model number, mounting thread, base configuration, connector orientation, sensitivity, and frequency response. A matching connector alone does not establish electrical or mechanical compatibility.
Q: Which sensitivity value applies to the 16699-10-02-01?
A: The supplied general specifications state 20 mV/mm/s, while the suffix matrix states 100 mV/mm/s for option code 10. This discrepancy requires confirmation before selecting or calibrating a replacement.
