Application :

A.S.I. Sales Pvt. Ltd. Electronic Horizontal Chain and Rope Testing Machine is designed to test chains and ropes under tension

Principle of Operation :

Operation of the machine is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The hydraulic system is ideal since it replaces transmission of load through Pressure sensor , which does not get damage due to shock on rupture of test pieces.
 

Load is applied by a hydrostatically lubricated piston Main cylinder pressure is applied to specimen through a load cell which senses load. Displacement of the piston is transferred to a rotary encoder through rack & pinion arrangement. Load cell & rotary encoder signals are processed in microprocessor based measuring panel where load & displacement are indicated digitally

Control Panel :

The control panel consists of a power pack complete with drive motor and an oil tank, control valve, and electronic measuring panel.
 

Power Pack :

The unit generates a maximum pressure of 200 kgf / cm2 The hydraulic pump provides continuously non-pulsating oil. Hence the load application is very smooth.

Hydraulic Controls :

Hand operated wheels are used to control the flow to and from the hydraulic cylinder. The regulation of the oil is infinitely variable. Incorporated in the hydraulic system is a regulating valve which maintains a practically constant rate of crosshead movement.

Mesuring Systems :

Measuring system of these machines consists of a precision pressure transducer for measuring load, a rotary encoder with rack and pinion arrangement to measure displacement and a microprocessor panel to indicate load and displacement digitally. The panel provides membrane key board to tare load and reset displacement instantly by touch of key. Test results like peak load, displacement at peak load and displacernent  at rupture U.T.S., % elongation etc. are available on panel

RS-232C Serial interface is provided to transfer test data to computer. Window based software is available to provide real time plot and data storage on PC.

Accuracy and Calibration :

A.S.I. Sales Pvt. Ltd. Electronic Horizontal Chain and Rope Testing Machines are closely controlled tor sensitivity, accuracy and calibration during every stage of manufacture. Every Machine is then calibrated over full range in accordance with British Standards 1610-1964 and IS :1828-1975.

A.S.I. Sales Pvt. Ltd.Horizontal chain Rope Testing Machine comply with Grade "A" of BS 1610-1964 and Grade 1.0 of IS 1828-1975. An accuracy of ±1% is guaranteed from 2% to 100 % of full load.
