Installation Requirements

Requires 1 sensor and 3 measurement locations for 3 measurement readings (X, Y, Z).

Backup sensors are recommended in case sensors are dropped or damaged on the route.

Installation Considerations

Needs 3 mounting spaces prepared for
3 measurement readings.

For machines with measurement locations in hard-to-reach places, this poses potential human safety risks.

Needs 1 mounting space prepared for
3 measurement readings.

For machines with measurement locations in hard-to-reach places, this provides a benefit to eliminate human safety risks.

Cabling Costs

Lower cost

Backup cables are always recommended in case damage occurs on the route.

Higher cost

Backup cables are always recommended in case damage occurs on the route.

Performance Considerations

Higher resonant frequency allows for wider frequency response range.

More accurate readings on X axis and Y axis because of the placement of the single access accelerometer.

Lower resonant frequency allows for a limited frequency response range.

Collection Time

Longer collection time due to having to take readings from 3 measurement locations.

Shorter collection time due to having all the readings taken from 1 measurement location.

Needs 1 mounting space and related mounting hardware for permanent installations.

Cabling Costs

Higher cost

Requires the purchase of 3 cordsets. For long cable runs, this can add greater expense.

Lower cost

Only requires the purchase of 1 cordset. For longer cable runs, this can be a great cost saver compared to single axis sensors.

Performance Considerations

Less mass and stiffness which provides more data on high frequencies.
