By measuring the deflection of the timing belt with a known force the required tension can be applied. The acoustic sensor uses a Clavis patented technique for detecting the belt vibration signal whilst minimising ambient noise. This belt tension tester used the exclusive Micro-computer LSI circuit and crystal time base to offer high-accuracy measurement. A reflective tape must be fixed if necessary. Selection method of the wire diameter range of the material measured by the tensiometer: Since the tensiometer adopts a 2-point linear calibration method and the working principle of the tensiometer is to measure the joint force (pressure on the measurement point), and convert the component force through the parallelogram rule (material tension).

Correct V-Belt tensioning is the single most important factor necessary for long, satisfactory operation. Loose timing belt tensioning acts like a loosely-held piece of string, with a snapping action as in a high torque situation the string or timing belt will break because the added stress is more than the timing belt was designed to take. Meters commonly use a 3-roller system where the material travels through the rollers causing deflection in the center roller that is connected to an analog indicator or load cell on digital models. The correct timing belt tension is the lowest tension at which timing belts will transmit the required mechanical power and not ratchet teeth when the drive is under a full load. Its operating principle is based on the relationship between belt tension and the vibration frequency of the belt itself. We also use third-party cookies that help us analyze and understand how you use this website. When physical restrictions are present, it is possible to get useable readings with the sensor up to 50 mm (2 in) distance from the belt and/or tipped up to 45 from perpendicular. The sensor uses an infrared beam to detect the vibration of a belt strand and sends a signal to the meter. High-accuracy belt tension meter with measuring range of 0~750N, 0~120lb, 0~77kg, 0~114 seems. If the measured force is less than the required deflection force, lengthen the center distance. Proper tensioning cannot be stressed enough: too loose of tensioning will cause the timing belt to ratchet (tooth jumping), while too tight of tensioning will possibly cause damage to the bearings, shafts and other drive components besides dramatically reducing timing belt life. But it is not only when installing the belts that you have to pay attention to the correct pretension. For Belt Type. Timing Belt Unusual Noise (Excessive Noise), Timing Belt Length and Center to Center Distance Calculator, ContiTech Mechanical Power Transmission Drive Design Calculator, Timing Belt and Timing Belt Pulley - Installation, Timing Belt Tooth Profile & Pitch Interchangeability. why does belt tension matter? Recheck the timing belt tension and alignment after eight hours of operation to ensure the drive has not shifted. All rights reserved. It is also possible to measure the surface speed with a tachometer up to 99,999 revolutions per minute. The acoustic sensor is particularly suitable for belts which vibrate poorly or where the amplitude of belt vibration is very small. Set point: The set point for belt tension is specified as natural frequency in Hz or as strand force in N. It is depending to the characteristics of the drive. A belt tension meter measures the belt tension of a belt when it is stationary. The target values for the belt tension are specified by the manufacturer of the system or the belt depending on the area of application, material and construction. When using a pencil style tension gauge, the deflection scale is calibrated in inches of span length. PDF SKF Belt Frequency Meter user manual The sensor uses an infrared beam to detect the vibration of a belt strand and sends a signal to the meter. A tensiometer is a tool that measures the force required to move the tensiometer plunger a given distance. In many applications, the belt tension meter is used to determine the natural frequency of the tensioned belt. Research on calibration method of mechanical belt tension meter Belt tension meter | norelem Belt Tension Meter | PCE Instruments As the tension in the belt increases the frequency of vibration also increases. PDF Sonic Belt Tension Meter - UNITTA The belt is toughed by hand to create vibration. Measurement: The belt is tapped in order to make it natural oscillating. This force can be compared to a table of recommended tension forces to determine the status of the belt. The optical sensor uses an invisible infrared beam to detect vibrations of the belt. The belt tension meter is an optically measuring maintenance tool for determining the belt tension force. The relationship between the measured frequency and the tension of the belt should be determined from a calibration test on the belt span. The BTM-400PLUS picks up the vibration frequency of the Free Belt Span and displays it, or the corresponding belt tension, on the instrument's LCD display panel. Care must be taken to ensure the light is sufficiently reflected by the belt. The belt tension meter is an optical measuring instrument for determining the belt tension force. sisco is responsible for providing free spare parts, and free technical support to assist the customer to repair the defective products until the problem is solved.

Tension meter - Wikipedia This vibration is inaudible and not usually visible. T-ACE measures frequencies between 10 and 5000 Hz and can be used in a wide range of layouts. Belt frequency meter | SKF Damage from use of parts other than sisco approved. Lengthen the center distance or adjust the tensioning idler to remove any timing belt slack. If the measured force is greater than the required deflection force, shorten the center distance. Single roll tension sensors and sonic tension meters are other types of tension meters. These are basically necessary to build up a tension-controlled closed loop. (Cable length: 1m). The frequency is then sent to a microcomputer, which then digitally displays load. Using a tape measure, measure the span length of the drive in inches. Tensiometer - T-ACE - Tsubakimoto Chain - DirectIndustry (Care should be taken when the span is longer than 1m.
