Vibration Meter provides periodic routine equipment checks.

Press Release Summary:

Housed in 7.5 x 4 x 2 in. plastic case with detachable probe, Model VM-300 operates from piezeoelectric accelerometer and incorporates charge amplifier input stage. Operation is controlled by internal microcontroller, acting under direction of 7-key membrane keypad. Powered via internal battery or external AC adapter, handheld meter includes acceleration, velocity, and displacement measurement modes. Low-voltage lockout circuit prevents meter from making erroneous readings due to low battery.

Hand Held Vibration Meter Offers Portability and Ease of use for Periodic Routine Checks of Industrial Equipment

Columbia Research Laboratories has introduced the Model VM-300 vibration meter, a general purpose vibration measuring instrument designed for periodic routine checks of industrial equipment where portability and ease of use are required. Acceleration, velocity, and displacement measurement modes are provided, along with a number of value enhancing features. Dual power allows the VM-300 to be powered from its internal battery in the field or from an external AC adapter to save battery life in bench applications. A precision low-voltage lockout circuit prevents the VM-300 Meter from making erroneous readings due to low battery. An automatic 10 minute timeout during battery operation will not allow the meter to drain the battery while unattended. An optional printer can be connected to the VM-300 Meter for permanently recording measurements.

An ideal preventive maintenance tool, the VM-300 operates from a rugged precision piezoelectric accelerometer and incorporates a charge amplifier input stage for stability and minimizing errors. Operation is controlled by an internal, integrated micro-controller, acting under direction of a splash resistant 7 key membrane keypad. The sensor probe contains Columbia's piezoelectric accelerometer which outputs an electric charge proportional to the instantaneous value of the applied acceleration. This charge signal is communicated to the VM-300 instrument through a low noise coaxial cable. The VM-300 is housed in a 7.5" x 4" x 2" plastic case with detachable probe and is supplied with a padded carrying case and AC adapter.
