سنسور وزن – لودسل 50KG مدل GML692
این سنسور وزن، که بعضاً فشارسنج نامیده می‌شود، نوعی سنسور است که
از آن برای تشخیص و اندازه‌گیری وزن استفاده می‌شود و در واقع همان حسگر موجود در
ترازوی دیجیتال است. لودسل‌ها به سه نوع هیدرولیک، پنوماتیک و فشارسنج تقسیم می‌شوند.
این سنسور از نوع فشارسنج با ساختار نیم پل است که باعث ایجاد سیگنال ولتاژ می‌شود،
در حالی که نیم پل توسط نیرو کشیده می‌شود. لودسل دارای سه سیم پایانه می‌باشد: یک
سیم مشترک، یک سیم برای منبع تغذیه و یکی برای ارسال وزن متناسب با ولتاژ. همچنین
می‌تواند برای ساخت مقیاس وزنی استفاده شود.
Introduction
A load cell is a
transducer that converts force into measurable electrical output.

This straight bar load cell (sometimes called a strain
gauge) can convert pressure (force) into
an electrical signal. Load cells are specially shaped metal
parts that have strain gauges glued to them. The strain gauges are resistors
that change their resistance when they are bent. When the metal part bends, the
resistance of the load cell changes

Load cells generally consist of a spring element on which strain
gauges have been placed. The spring element is usually made
of steel or aluminum. That means it is very sturdy but also
minimally elastic. As the name “spring element” suggests,
the steel is slightly deformed under load, but then returns to
its starting position, responding elastically to every load. These
extremely small changes can be acquired with strain
gauges. Then finally, the deformation of the strain gauge is interpreted
by analysis electronics to determine the weight.

There are many varieties of load cells like
Compression/Tension Load Cells, S-Beam Load Cells,
Bending Beam Load Cells, Platform, and Single
Point Load Cells, Canister Load Cells, Low
Profile Load Cells, etc.

The method of operation can involve either
the use of a weight balancing mechanism or the detection of
the force developed by mechanical levers.

Load cell designs can be distinguished according to the type of output signal
generated (pneumatic, hydraulic, electric) or according to the way
they detect weight. (bending, shear, compression, tension, etc.)
