Description

The Pro-Range GML642 is a specialized force washer sensor, functioning as a compact load cell designed for direct integration into bolted joints and structural assemblies. It utilizes precision strain gauge technology bonded to a stainless steel body to convert applied force into a proportional millivolt-per-volt (mV/V) electrical signal. This analog output is stable and highly linear, suitable for connection to data acquisition systems, PLC analog input modules, or dedicated load cell amplifiers.

Engineered for industrial and R&D environments, its IP66-rated housing protects the internal sensing elements from dust ingress and powerful water jets, ensuring reliable operation. The sensor’s wide operating temperature range and high overload resistance make it a versatile component for monitoring tensile or compressive forces in machinery, structural testing rigs, and process control systems where space is constrained.

Key Features

  • High-Accuracy Strain Gauge Sensing: Delivers a precise 1.5±5% mV/V output with ≤ ±0.5% F.S. non-linearity, hysteresis, and repeatability error.
  • All-Stainless Steel Sensing Element: Provides excellent corrosion resistance, mechanical strength, and long-term measurement stability.
  • Optimized Washer Form Factor: The circular design with a customizable inner hole allows for direct mounting on bolts and shafts.
  • Robust Environmental Specifications: IP66 protection rating and an operating temperature range of -20°C to +80°C.
  • Safe Overload Capacity: Built to withstand forces significantly above its rated 10kN capacity without permanent damage.
  • Standard Excitation Voltage: Designed for use with a 9-15 VDC supply, compatible with common industrial power sources.
  • High-Value Build: Offers professional-grade measurement performance and durability in a cost-optimized package.

Applications

  • Bolt Preload and Clamping Force Monitoring: Integrated into bolted joints in structural frameworks, pressure vessels, and heavy machinery.
  • Industrial Process Control: Force feedback in presses, injection molding machines, and material testing equipment.
  • Research & Development Load Testing: Precise force measurement in mechanical testing rigs and prototype validation.
  • Robotic End-Effector Force Sensing: Provides tactile feedback for robotic grippers and assembly arms.
  • Structural Health Monitoring: Embedded within assemblies to monitor stress and load distribution over time.

Frequently Asked Questions

What is the output signal of the GML642 force washer sensor?

The GML642 provides a ratiometric analog output of 1.5 ±5% millivolts per volt (mV/V). This means the output voltage signal is proportional to both the applied force and the excitation voltage supplied (9-15 VDC). This signal is standard for strain gauge load cells and requires connection to a compatible load cell amplifier or PLC analog input module for signal conditioning and interpretation.

What is the recommended wiring and power supply for this sensor?

The sensor requires a 4-wire connection (Excitation+, Excitation-, Signal+, Signal-) and operates on a recommended DC excitation voltage between 9 and 15 volts. It is critical to use shielded cable for the signal wires to minimize electrical noise interference, especially in industrial environments. The output wires should be connected directly to a dedicated load cell amplifier or a high-resolution analog-to-digital converter.

Can this force washer sensor be used for both tension and compression measurements?

Yes, the GML642 is a bi-directional sensor suitable for measuring both tensile (pulling) and compressive (pushing) forces up to its rated 10kN capacity. The output signal polarity will change based on the direction of force. Ensure your mounting hardware and assembly allow for clear force transmission along the sensor's primary axis for accurate measurement.

What does the IP66 rating mean for installation?

An IP66 rating indicates the sensor is completely dust-tight (6) and protected against powerful jets of water from any direction (6). This allows for reliable operation in outdoor environments or industrial settings where exposure to dust, dirt, and water washdown is a concern. However, it is not submersible for prolonged periods.

Is calibration required, and can the inner hole be customized?

While the sensor is factory-calibrated, system-level calibration is recommended after installation to account for mounting effects and amplifier offsets for highest accuracy. As indicated by the manufacturer, the inner hole diameter can be customized for specific bolt sizes; such customizations require direct contact with the supplier's sales team prior to order placement.
