|Drive belts achieve maximum lifetime and efficiency when tensioned to the manufacturer’s recommended tension.
The new CHECK•LINE® BTM-400PLUS Belt Tension Meter provides an easy, reliable method for accurately measuring static tension in flat, V-, cog or toothed belts of rubber, leather, fabric, plastic and composite materials.
The BTM-400PLUS’s hand-held, LED-optical sensor is cable-connected to the gauge body, which contains a microprocessor that converts the sensor signal to a pre-selected reading of either Belt Vibration Frequency (Hertz) or Belt Tension (Newtons [N] or pounds / force [lbf]).
Results are displayed on a bright, easy-to-read LCD display. An acoustic signal indicates a successful measurement.
|The BTM-400PLUS’s LED-optical sensor is unaffected by ambient noise, offering improved performance versus competitive, acoustic sensor-based designs|
