Type 3 Optical
Belt Tension meter for long span mesuring
The only belt meter suitable for long-span/thick transmission belts of large machines or blowers. It uses infrared to detect belts outdoors or indoors without being disturbed by environmental noise. It is the best tool for belt maintenance.
Features
Long belt spans, vee and synchronous belts, for Industrial measurement applications range. Measurements down to 10Hz are easily achievable so that tension measurements may be made in belt spans of 5 metres or more.
Measurements may be taken down to 4 Hz provided that the sensor head is fixed. The sensor head is 'beamed' onto the belt from distances of up to 50mm (2 inches) or more and may be directed at the flat side of the belt or the edge. The sensor is also relatively insensitive to the angle of approach. An additional advantage of the optical head is that the sensor is totally unaffected by any level of background acoustic noise.
The type 12 optical sensor and meter uses advanced signal processing techniques to avoid such interference. It should be remembered that at very low frequencies handshake may impart a false vibration onto the sensor head. A guide finger on the sensor may be adjusted to rest against a supporting face to minimise handshake vibrations.
