About BURSTING strength tester analog gauge

A Bursting Strength Tester (Analog) is a laboratory testing instrument used to measure the resistance of materials (like paper, paperboard, corrugated board, fabrics, and packaging materials) against bursting force applied under uniform hydraulic pressure through a rubber diaphragm. In the analog type, the bursting strength is indicated on a circular dial gauge (analog manometer) instead of a digital display. --- a i, Working Principle 1. The test sample (paper, board, fabric, etc.) is clamped tightly. 2. Pressure is applied hydraulically via a rubber diaphragm. 3. As pressure builds, the diaphragm expands and forces the sample to burst. 4. The maximum pressure (kg/cmA or psi) at which the sample bursts is shown on the analog gauge. --- Main Components Analog Dial Gauge (Manometer) a shows bursting strength reading in kg/cmA or psi. Rubber Diaphragm a expands and transmits pressure to the sample. Clamping System a holds the sample firmly to avoid slippage. Hydraulic System / Pressure Pump a generates pressure. Release Valve a to release pressure after the test. Rigid Frame / Body a ensures stability.
