compression spring force tester
Model TDW-300 Computer compression spring force tester
Features :
High accuracy servo motor to control test speed.
Ball screw no backlash to guarantee the low noise and high driving efficiency High accuracy load cell to measure the test load
High accuracy photoelectric encoder to measure the displacement Compact structure with easy operation
Limit switch and setting in the software to guarantee the safety
The software consists of function modules such as dynamic communication, speed control, parameter input, data processor, result observation, record retrieval, chart display and printing, and data storage. Various kinds of test methods: test of residual height and deformation of spring under pre-set test load; test of 9 test load under preset height or deformation of spring, etc. Multiple points data auto-collection: avoid the impact of spring stress on the testing data. Thus the total testing
Process is completely automatic.
Overload protection and thus keep the load cell free of damage.
Multiple databases, such as swing spring and shaft spring, etc., can be available for users when taking following tests.
The tester has strong functions of data processing and mathematical statistics. It can draw the stiffness curve and calculate the segment stiffness, carry on data statistics, plot the normal distribution curve and calculate the index of process capacity
Being a professional spring testing machines suppliers ,do truly hope to service you .
Force Measurement:
Load accuracy meets or exceeds Grade 1 ASTM E4, ISO7500-1. EN10002-2, BS1610, DIN51221
Displacement Measurement:
Encoder over 2000pulse/turn to guarantee the accurate displacement, the encoder is installed with the ball screw, and the ball screw to drive it turning directly.
Speed setting
Speed can be set between 0.01 -250mm/min by computer, and the excellent servo motor can support the high speed, and the speed can be extended by special offer.
