1. Applications and features:

LAW series Microcomputer Control Electro-hydraulic Servo Steel Strand Tensile Testing Machine adopts the cylinder underneath type main engine, use a load cell to measure force. The machine configured import oil pump unit and independent low noise clamping oil source. Use Digital program-controlled amplifier to achieve all sorts of model of the closed-loop control such as constant force, constant stress, constant deformation, constant speed, etc. The machine is mainly used for measuring and analyzes tensile strength of steel strand and could satisfy the requirements of GB/T5224-1995 “Prestressed Concrete Steel Strand”

3. Functions

(1) Automatic computer servo control function

●Automatic control, measure, data collection and processing, draw and print the test curve and report

● Observe and control system can automatic calibration and zero set.

● Stepless speed regulating, in the study it can be arbitrary smooth transition and maintain the same speed.

● Data storage and curve amplifier. In the study can be arbitrary show different test curve.

● During the automatic operation process, it can change to artificial control.

● Have automatic protection function, the protection range can be set in a random manner.

4．Advantages:

(1) Use manual and automatic operation to raise the working efficiency.

(2) Adopt spoke structure loading sensor. It has the advantage of high precision and stable performance.

(3) Equipped with Italian oil cylinder protection system, low noise and stable oil.

(4) Hydraulic sealed with double sealing structure, effectively prevent the leakage of oil and oil leakage.

(5) Configured Clamp mouth protection board, this could effectively prevent the splint of clamp mouth scratched.

(6) Equipped with Universal Ball Head Institution, this could be automatically adjustable cores, and to ensure the sample clipped absolutely right.
