Product Overview and Key Features

The PST load cell sensor is an alloy steel strain gauge load cell with IP65 protection, available in nominal capacities from 1kg to 10kg. Built for durability, the IP65 weight sensor provides dust-tight enclosure protection and reliable water resistance for splash and light jet exposures, making it suitable for both factory floor and laboratory environments. The strain gauge load cell design ensures consistent performance, while PST’s manufacturing and calibration processes achieve an accuracy of 0.3% FS, making this high-accuracy weighing solution ideal for precision testing machines and mold monitoring.

Mechanical Design and Materials

Constructed from alloy steel, this strain gauge load cell balances strength and cost-effectiveness for long service life. The alloy steel body resists deformation and provides stable mechanical properties across the specified operating range. The IP65 weight sensor’s mechanical design incorporates mounting features compatible with standard testing machine setups and mold fixtures, ensuring straightforward integration into existing assemblies. Internal mechanical isolation and robust bonding protect the strain gauges from mechanical shocks and environmental contamination, further enhancing long-term stability.

Strain Gauge Technology and Signal Integrity

At the heart of the PST load cell sensor is a full-bridge strain gauge configuration that converts mechanical load into a precise electrical signal. The strain gauge load cell uses industry-standard foil gauges, accurately bonded to the alloy steel flexural elements. This arrangement allows the IP65 weight sensor to produce a reliable, high-fidelity signal even under small load changes. The high-accuracy weighing performance of the PST strain gauge load cell is achieved through careful bridge balance, temperature compensation, and optimization of gauge placement to minimize non-linearity and hysteresis.

Accuracy, Calibration, and Performance

PST ensures each strain gauge load cell undergoes rigorous calibration and testing to achieve an accuracy of 0.3% FS. The calibration process includes multi-point loading and verification against traceable standards to ensure the IP65 weight sensor meets performance criteria across the entire 1kg–10kg range. Repeatability and hysteresis are tightly controlled, and PST provides detailed calibration certificates on request. This high-accuracy weighing component supports demanding applications in testing machines where precise force or weight feedback is critical for quality control and process optimization.

Environmental Protection and Durability

The IP65 rating of the PST load cell sensor guarantees protection against dust ingress and low-pressure water jets from any direction. This makes the IP65 weight sensor appropriate for environments where airborne particulates or occasional wash-downs are present. The alloy steel construction, combined with sealed cable entry and corrosion-resistant coatings, ensures durable operation in industrial settings. For applications requiring additional protection, PST offers optional environmental sealing and specialized connectors to enhance ingress resistance beyond the IP65 baseline.

Applications and Use Cases

The PST strain gauge load cell is well-suited for testing machines, mold presses, quality control rigs, and precision weighing systems. Typical uses include force measurement in material testing machines, weight feedback in injection molding presses, load monitoring in automated assembly lines, and high-accuracy weighing in laboratory instrumentation. The IP65 weight sensor’s combination of compact size, robust mechanical design, and high-accuracy weighing capability makes it a versatile choice for OEMs and system integrators seeking reliable sensor performance.

Integration and Compatibility

PST designed the load cell sensor to be easy to integrate with common signal conditioning electronics, data acquisition systems, and programmable controllers. The strain gauge load cell output is compatible with standard instrumentation amplifiers and digital converters, enabling straightforward connection to PLCs, data loggers, and weight indicators. For customers requiring plug-and-play solutions, PST can supply matched amplifiers and interfaces that optimize the IP65 weight sensor for specific testing machine platforms and mold control systems.
