Description

The GML668E load cell utilizes advanced metal foil strain gauge technology bonded to a high-strength alloy body. When force is applied, the strain gauge experiences a minute deformation, causing a proportional change in its electrical resistance. This change is output as a low-level millivolt-per-volt (mV/V) signal, which is then amplified and converted by external instrumentation for precise force or weight measurement.

Engineered for durability, the sensor features a compact, IP66-sealed housing that protects the internal strain gauge from dust ingress and high-pressure water jets. Its wide operating temperature range and robust overload protection (150% safe, 200% ultimate) make it suitable for integration into automated production lines, material testing machines, and robotic force feedback systems where space is constrained but reliability is critical.

Key Features

  • High-precision metal foil strain gauge technology ensures long-term stability and low hysteresis.
  • Compact, low-profile design ideal for integration into space-limited assemblies and machinery.
  • IP66 ingress protection rating guarantees reliable operation in dusty or wet industrial environments.
  • Wide supply voltage range of 5-15 VDC allows for flexible system power design.
  • High overload capacity with 150% safe overload and 200% ultimate overload protection safeguards the sensor.
  • Matched input and output resistance (700Ω ±10Ω) simplifies signal conditioning circuit design.
  • Optimized performance-to-cost ratio for high-volume OEM applications requiring precise force monitoring.

Applications

  • Precision force monitoring in automated assembly and robotic gripper systems.
  • Material testing and quality control in benchtop tensile/compression test stands.
  • Process control and overload detection in industrial packaging and filling machinery.
  • Force feedback and end-effector load measurement in collaborative robotics (cobots).
  • Medical device testing and biomechanical research equipment.

Frequently Asked Questions

What is the recommended excitation voltage for the GML668E load cell?

The GML668E load cell is designed to operate with a recommended excitation voltage between 5 and 15 VDC. Applying voltage within this range ensures the specified output signal of 1.5±10% mV/V and maintains sensor accuracy and long-term stability. Always use a stable, regulated DC power supply to minimize signal noise.

How do I interface the 1.5mV/V output signal with a PLC or data logger?

The low-level mV/V output requires signal conditioning. You will need an external instrumentation amplifier or a dedicated load cell signal conditioner module. These devices amplify the small signal, provide bridge completion, and often convert it to a standard industrial signal like 0-10V or 4-20mA, which can be directly read by PLC analog input modules or data acquisition systems.

Can this sensor be used for both tension (pulling) and compression (pushing) forces?

Yes, the GML668E is a dual-purpose tension and compression force sensor. Its mechanical design allows it to accurately measure forces applied in both axial directions. Ensure the mounting hardware and mechanical fixtures are correctly designed to guide the force purely along the sensor's primary axis to prevent side loads that could affect accuracy.

What does the IP66 rating mean for installation?

An IP66 rating indicates the load cell is totally protected against dust ingress and can withstand powerful water jets from any direction. This allows for installation in wash-down environments, outdoor applications, or dusty industrial settings. However, it is not submersible; for permanent immersion, a higher IP rating (like IP68) would be required.
