I. Prestressed Steel Cable Tension Meter Electrified Railway Cable Force MeterSL-20TModel Description:

Range: 10T, 20T.

Instrument Accuracy: This instrument requires measurement according to the specifications of the calibrated cable number, with a measurement accuracy within 2%-5%.

II. Working Principle of SL-20T Cable Tension Meter

Using the principle of force decomposition, when the system is balanced:

T= 2F× cos(a/2)  

Where: T is the thrust; F is the cable tension; a is the angle between the two sides of the cable.

Since a is fixed and identical, T is proportional to F. The force T acts on the force-sensitive sensor, which outputs a signal. After circuit operation, correction, and amplification, the value displayed on the screen is the tension of the measured cable.

III. Structure of SL-20T Cable Tension Meter

Prestressed Steel Cable Tension Meter Electrified Railway Cable Force MeterOperation Panel

Buttons from left to right are "ON/OFF", "+", "-", "ENTER/ZERO"; the five-digit number displayed on the upper LCD is the cable tension, unit is. Tighten the handwheel until the cable reaches the limit, and the cable tension will be displayed.

a)No operation, automatically shuts off after 30 minutes. After measurement, press the "ON/OFF" key to turn off the power.

b)*Please provide cable structure, diameter, and material for quotation
