Load Pin SM-P23L

Product Description

The SM-P23L load pin has a compact structure, a simple geometric shape, strong anti-torsion and anti-bending capabilities, stable performance and easy to install. It is widely used in the measurement of goods at ports and docks, as well as in the safety inspection of hoists and lifting equipment. An optional built-in amplifier 4-20mA is available.

Description

strong anti-eccentric load capacity.
High measurement accuracy and stable performance.

Dimensions（In mm. 1mm=0.03937 inches）

Measurement Principle

The pin sensor utilizes the elastic deformation of an elastic body under the action of an external force, causing the resistance value of the resistance strain gauge adhered to its surface to change (increase or decrease). Then, through the corresponding measurement circuit, this resistance change is converted into an electrical signal (voltage or current), thereby completing the force measurement process.
