Description

The GML642 force washer sensor utilizes a precision strain gauge circuit bonded to a high-strength stainless steel body. When force is applied, the resulting strain produces a millivolt-per-volt (mV/V) output signal proportional to the load. This analog output is stable and linear across the specified temperature range, making it suitable for integration into PLCs, industrial scales, and test stands.

Engineered for demanding environments, its IP66 rating ensures reliable operation where dust and directed water sprays are present. The sensor’s through-hole design allows for straightforward mounting via bolts or studs, making it an ideal component for force monitoring in structural testing, bolt tensioning, and heavy machinery load monitoring applications.

Key Features

High-precision strain gauge technology with ±0.5% F.S. non-linearity, hysteresis, and repeatability error.
Rated output of 1.5 mV/V ±5% for consistent signal scaling with 9-15 VDC excitation.
All-welded SUS-304 stainless steel housing provides excellent corrosion resistance and mechanical strength.
IP66 protection rating safeguards internal electronics from dust ingress and powerful water jets.
Wide operating temperature range of -20°C to +80°C with internal temperature compensation.
High overload capacity (typically 150% of rated load) for enhanced durability in dynamic applications.
Compact and space-saving circular form factor with a customizable inner hole diameter.
Low-profile design is ideal for integration into presses, bolted joints, and force-limited assemblies.

Applications

Industrial bolt tension monitoring and pre-load measurement in structural engineering.
Force feedback and overload protection in hydraulic presses and material testing machines.
Load monitoring for heavy machinery, crane hooks, and hoist safety systems.
Process control and weighing systems in manufacturing and assembly lines.
Research and development applications requiring precise static and dynamic force measurement.

Frequently Asked Questions

What is the excitation voltage requirement for the GML642 force sensor?

The GML642 force washer sensor requires a DC excitation voltage between 9 and 15 volts. Operating within this range ensures the rated output of 1.5 mV/V and maintains specified accuracy. A stable, regulated power supply is recommended for optimal performance.

How is the sensor's output signal interpreted?

The sensor provides a millivolt-per-volt (mV/V) analog output. With a 10 VDC excitation and a 50kN load, the output voltage will be approximately 15 mV. This signal must be connected to a compatible instrumentation amplifier, signal conditioner, or data acquisition module with a high-impedance differential input for accurate measurement.

Can this sensor be used for dynamic or impact force measurements?

While primarily designed for static and quasi-static force measurement, its robust construction and high overload capacity allow it to handle some dynamic loads. For high-frequency impact measurements, consult the sensor's natural frequency specifications and consider using a sensor specifically rated for dynamic applications.

What mounting considerations are important for accurate measurement?

Ensure the mounting surfaces are flat, parallel, and clean to avoid bending moments or side loads that can induce measurement error. The force must be applied axially through the sensor's center. Use appropriate washers and follow recommended torque values for mounting bolts to prevent damage.

Is the cable included, and what is its length?

Yes, the sensor includes an integral, shielded 4-wire cable. The standard cable length is typically 3 meters, providing flexibility for installation. The cable wires are color-coded (Red: Excitation+, Black: Excitation-, Green: Signal+, White: Signal-) for straightforward connection to signal conditioners.
