Product Introduction

This portable instrument separates the display from a single external piezoelectric accelerometer so the sensor can remain firmly coupled to a motor, fan, pump or air-handling unit while the technician reads the result. Selectable acceleration, velocity and displacement modes describe different aspects of machine motion, with peak acceleration supporting high-frequency screening, RMS velocity indicating overall severity and peak-to-peak displacement representing movement amplitude. A magnetic base improves repeatability on clean ferrous surfaces, while a threaded contact probe provides fast comparative checks where magnetic attachment is impractical.

Key Features

External piezoelectric accelerometer isolates the measurement point from handheld enclosure movement.

Acceleration, velocity and displacement modes support bearing, overall-machine and motion-amplitude checks.

Selectable low- and high-frequency bands help separate rotational vibration from higher-frequency impacts.

RMS, Peak and peak-to-peak indications match the selected vibration quantity and survey method.

Coiled sensor cable extends to machinery points while remaining compact during walk-around inspections.

Interchangeable magnetic base and stainless contact probe suit repeatable or rapid screening measurements.

Customer Product Concerns

Comparable machine-vibration readings require the same measurement point, axis, sensor coupling, frequency band and amplitude convention, because a change in mounting method can alter the observed response.

Readings can change when the sensor is moved to a different point, direction or mounting surface.A magnetic base and marked measurement location keep sensor position and orientation consistent for trend comparison.

One vibration value cannot describe both overall machine motion and short high-frequency impacts.Selectable velocity, displacement and acceleration modes present RMS, peak-to-peak and Peak quantities appropriate to the check.

Cable movement or tension can disturb a small accelerometer during measurement.The flexible coiled lead and molded strain relief allow a slack service loop beside the mounted sensor.

Some housings are curved, painted or non-magnetic and cannot hold a flat magnetic base securely.An interchangeable stainless contact probe supports quick comparative screening when rigid magnetic coupling is unavailable.

Typical Applications

Cleanroom air-handling-unit vibration surveysMotor, fan and pump condition screeningBearing-housing comparative measurementsEquipment commissioning and post-maintenance checksRoutine trend collection at marked machine points
