ESMLS15 Alloy steel material Ring-shaped load cell sensor
Working Principle
ESMLS15 When an object acts on an annular weighing sensor, the weight of the object causes a slight deformation of the annular elastic body, and the resistance of the strain gauges attached to the surface of the elastic body changes with the deformation. The change in resistance is converted into a voltage signal through a Wheatstone bridge circuit, and after processing such as amplification and filtering, an electrical signal proportional to the weight of the object is output, thereby achieving the measurement of the object's weight.
Product Features

application scenarios
1. Bolt / Fastener Preload Monitoring (Most Common)
Scenario: Wind power flanges, pressure vessels, high-strength bridge bolts, construction machinery, aerospace fasteners.
Purpose: Accurately control tightening torque, monitor bolt loosening/load changes in real time, prevent loosening, ensure safety.
Installation: Sensor is sleeved under the bolt, between the nut and flange, directly measuring axial clamping force.
2. Geotechnical / Prestress Monitoring
Scenario: Slope anchors, foundation pit anchor cables, tunnel arch supports, geotechnical anchoring projects.
Purpose: Real-time monitoring of anchor/anchor cable tension, assess anchoring effectiveness, construction and long-term health monitoring.
Installation: Sleeved at the end of the anchor rod, between the anchor hardware and the base plate.
3. Press-Fit / Riveting / Punching Force Control
Scenario: Automotive component pressing, bearing pressing, motor rotor pressing, metal stamping.
Purpose: Online monitoring of pressing force and displacement curves, determine press-fit quality, prevent overpressure/underpressure.
Features: Fast dynamic response, suitable for high-frequency cyclic force measurement.
4. Bearing / Axial Force / Roller Load Monitoring
Scenario: Rolling mill bearing seats, crane rollers, conveyor rollers, spindle axial force.
Purpose: Monitor axial load distribution, protect equipment from overload, predict service life.
Installation: Sleeved on the shaft, between the bearing end face and the seat ring.
5. Mold / Fixture / Clamping Force Measurement
Scenario: Injection molding machine clamping force, hydraulic press die clamping, chuck clamping force, tooling fixtures.
Purpose: Precisely control clamping force, prevent deformation, ensure product consistency.
6. Cable / Rope Tension Monitoring
Scenario: Crane steel ropes, suspension bridge cables, elevator wire ropes, tension pulley force.
Purpose: Real-time tension measurement, prevent rope breakage, balance multi-rope loads.
7. Military / Aerospace / Special Equipment
Scenario: Rocket fixture loads, launch pad preload, ship hatch clamping force, explosion-proof equipment.
Features: High precision, high reliability, shock-resistant, customizable explosion-proof/high-temperature types.
