Frequently Asked Questions

1. What is the fundamental difference between GML670 Full Bridge and Half Bridge?
A Full-Bridge sensor (4-wire) is a complete circuit for high accuracy. A Half-Bridge sensor (3-wire) is typically used in groups of 4 to form a full bridge, common in consumer products like body fat scales.
2. Why does GALOCE prioritize Manganese Steel over Stainless Steel for GML670?
Manganese Steel (锰钢) provides superior elasticity and a much higher fatigue limit for ultra-thin sensors, ensuring the sensor returns to zero precisely even after repeated high-cycle weighings.
3. Can I order the GML670 with custom connectors like JST or Molex?
Yes. We specialize in providing "Plug & Play" solutions. We can customize cable lengths and pre-install various industrial-standard connectors to match your PCB directly.
4. Is the GML670 series suitable for high-vibration drone applications?
Yes. The manganese steel structure and professional sealing provide excellent stability against vibration, making it ideal for monitoring liquid tank depletion in agricultural drones.
5. Do you provide 3D CAD models for GML670 and GML670A?
Yes. We provide comprehensive technical support including 2D/3D CAD drawings for all variants. Please contact our engineering team to receive the exact files for your design.

GML670 micro load cell for smart medical

Background

With the aging of the world and people's pursuit of a healthy and happy life, the medical robot industry will usher in a flashpoint. Medical robots are an inevitable trend of technological development. Continuing to expand the breadth, depth, speed, and precision of medical robot innovation, and accelerating the extension to more intelligent and refined medical and health care, life services and other fields will help to achieve "jointly protect human beings." A great vision for a healthy and better future".

Problems faced by customers include

A team of medical device engineers from the United States, they wanted to design a flexible assessment and therapy system for the entire body, trains postural control and thus the basis of all movements in a sensitive, specific and meaningful way. our engineers recommended the GML670 load cell for their newly developed medical testing equipment after having an in-depth understanding of the functions they wanted to achieve. The GML670 load cell has a small size, good stability and high precision. Advantages, adapt to the small size installation space, and slightly improve the product in order to adapt to the installation structure.

Solutions

During the test, the customer feedback error is large. After checking the customer's installation pictures, it was found that the customer installed 3 sensors on one device. When two or more sensors are installed in parallel, it is necessary to debug the sensitivity of the three-piece group before leaving the factory. After the error reduction, within the range of customer requirements. During the installation, the customer feedback that the screw fixation is not suitable, and the threaded hole is customized according to the customer's screw diameter, which successfully solves the problem of installation and fixation.
