Product overview

The PST 0–1000T compression load cell is a heavy-duty digital load cell designed to measure compressive forces from small loads up to 1000 metric tons. As a precision weight sensor and force sensor, it converts compressive force into a high-resolution digital signal through integrated electronics, minimizing noise and compensating for environmental influences. The digital load cell format simplifies system integration by providing ready-to-use output formats, allowing direct connection to data acquisition systems, controllers, or test frames used in medical testing and calibration laboratories. This compression load cell is optimized for static and quasi-static measurements common in medical device testing, material compression testing, and calibration of force application equipment.

Key features and technical advantages

- Wide capacity range: The PST compression load cell covers a broad capacity span up to 1000T, providing a single model family for diverse test requirements. As a weight sensor and force sensor, it enables consistent measuring methodology across capacities, streamlining calibration and data comparability.

- Digital load cell output: The integrated digital conversion in this digital load cell reduces analog signal degradation and ensures stable, accurate readings over long cable runs. Digital output minimizes susceptibility to electromagnetic interference, an important advantage for sensitive medical testing environments.

- High accuracy and repeatability: Designed with precision strain gauge technology and advanced signal processing, the compression load cell offers excellent linearity, hysteresis, and repeatability. This ensures that the PST digital load cell reliably captures subtle variations in applied force and weight, critical for medical component testing and verification.

- Robust mechanical construction: The compression load cell is constructed from high-strength alloy steel or optional stainless steel to withstand heavy compressive loads, shock, and corrosive conditions. Mechanical robustness reduces downtime and maintenance needs in rigorous testing facilities.

- Temperature compensation and environmental protection: The PST digital load cell includes temperature compensation and environmental sealing to maintain measurement integrity across a wide temperature range and humid conditions. These protections make the weight sensor suitable for controlled laboratory settings and harsher industrial environments alike.
