Tensile Tester Drives and Sensors

1. Tensile testing machine screw drive VS rack drive

In general, the transmission can be divided into screw drive and rack drive. The screw drive has high precision and high test repeatability, so the price is also relatively expensive. The screw, which has a decisive effect on the measurement of tension accuracy. General ball screw, trapezoidal screw, general screw. Among them, the accuracy of the ball screw is the highest, but the performance of the ball screw depends on the operation of the computer servo system to play, the entire package price is also relatively expensive. The general screw and trapezoidal screw can be used to achieve the required precision of the flexible packaging, ie 0.5-1% accuracy. Rack drive is cheaper, accuracy is lower, test repeatability is lower, and common system operation is sufficient.

2. Tensile testing machine sensor, the main cost lies in the length of time it is its life, the length of life and its use of times. Among them, photoelectric induction is one of the more advanced technologies that can generally be used more than 100,000 times.
