A bearing housing or machine casing is the documented mounting location. The selected point must transmit the rotor vibration being monitored, because poor installation can reduce amplitude or frequency response and can create signals that do not represent the machine vibration.

The official datasheet names Trendmaster Pro Constant Current Direct Input Card 149811-02 and Seismic Direct Input Card 164746-01. The installed channel still needs the published constant-current excitation and connector arrangement for this accelerometer.

The channel should provide 18 to 28 Vdc at 2 to 20 mA constant current, and the sensor output bias should be 8 to 12 Vdc. Those references establish the electrical starting point before vibration readings are accepted.

Code 02 supplies a stainless-steel 1/4-28 to M8 x 1.25 stud for the sensor's 1/4-28 female mounting thread. The published mounting-torque range is 2.7 to 6.8 N m.

The manufacturer recommends up to 31 m when maximum vibration is 50 g, frequency is 10 kHz and cable capacitance is 200 pF/m. A longer route falls outside that published recommendation and requires a manufacturer-supported cable review.

Its published operating range is -54 to +121 degrees C, with IP68 protection and 100% condensing humidity specified as non-submerged. IP68 should therefore not be presented as permission for continuous submerged service.

CN is the China-specific approval and marking option used for accelerometers when CN0 is unavailable. It does not identify the country of manufacture, so receiving inspection should use the supplied unit markings for the required China approval context.

The published reference is an 8 to 12 Vdc output bias and no more than 2 seconds to settle within 1% of bias. A result outside those values leaves the electrical loop unresolved, so the constant-current supply, 2-pin connection and cable path should be reviewed before the acceleration signal is accepted.
