S Type Load Cell Sensor, 1T — Portable Tension and Compression
The S-beam design provides a simple, stable installation for measuring tension and compression. It offers high precision with 2.0±0.05mV/V sensitivity and a maximum 0.2% accuracy. The operating range spans -20℃ to +70℃, enabling use in varied environments. The sensor is built with threaded ends for secure mounting and includes a built-in protection line, with a tolerance to 50N tension for reliability.
Best for: small-to-midscale force measurement in lab setups or bench-scale testing. This model is ideal when you need precise readings in a compact form factor and straightforward installation.
Caution: Ensure compatible wiring and signal conditioning to preserve the 0.2% accuracy across your measurement range.
S Type Load Cell Sensor 5KG–5T — Versatile Tension/Compression
Designed for a wide range of scales and testing devices, this S-beam sensor emphasizes stability and ease of installation. Like the 1T variant, it features high-precision 2.0±0.05mV/V sensitivity and 0.2% accuracy, with an operating window of -20℃ to +70℃. Threaded ends support versatile mounting, and the built-in protection line aids durability under tension.
Best for: crews needing a broader load range from 5 kg up to several tons, with predictable performance across changing conditions.
Caution: Confirm electrical output compatibility (mV/V or other) with your data acquisition setup before purchasing adapters or converters.
BENGBUZZYQ S-Type Load Cell 5kg–20t — Stainless Steel
This model is engineered for precise bidirectional force measurement, supporting both tension and compression. It uses high-quality stainless or alloy steel for durability in demanding environments. It offers multiple signal outputs, including mV/V and 4–20mA, enabling easy integration with PLCs, weighing indicators, or DAQ systems.
Best for: industrial automation tasks, crane scales, and situations requiring robust build and flexible signaling options.
Caution: Review the available output formats to ensure compatibility with your existing control system and wiring harness.
Walfront Portable S-Type Beam 2000kg — Hopper Weight
With a high-capacity 2000 kg range, this portable S-type beam emphasizes durability and operational practicality in harsh environments like batching and asphalt plants. It features IP67 protection for dust and water resistance, making it suitable for outdoor or dusty settings. The device provides an analogue output for straightforward data transmission to compatible weighing equipment.
Best for: bulk weighing and large-scale material handling where environmental exposure is a concern.
Caution: The higher capacity may require more complex mounting and signal conditioning to maintain accuracy across the full range.
S Type Load Cell With Indicator — 0-500kg
This option pairs an S-type load cell with an integrated indicator display for immediate readouts. It offers a 0-500 kg range and dual relay outputs, enabling automatic switching based on preset weight thresholds. The design supports high-precision weighing with 0.2% accuracy and robust signal processing to deliver reliable data for control or alarm scenarios.
Best for: compact systems that require a ready-to-use package with an on-board display and easy threshold-based automation.
Caution: Ensure the indicator’s wiring and relay ratings match your control circuit to avoid mis-triggering external devices.
Buying Guide
What load cell range do I need?
Choose 1T or 5KG–5T for general lab or small-to-midscale weighing. For bulk or industrial use, consider 2000 kg or higher. Pick a device with an adequate safety margin beyond your expected maximum load.
What about accuracy and output signals?
Look for sensors with 0.2% or better accuracy and a known sensitivity (commonly 2.0±0.05 mV/V). Decide between mV/V outputs, 4–20 mA, 0–5 V, or other formats based on your DAQ or PLC. Some models offer multiple outputs for flexibility.
How important is protection and environmental suitability?
IP ratings (e.g., IP67) protect against dust and water. For outdoor or harsh environments, stainless steel construction and protective lines improve durability. Consider operating temperatures and whether the sensor can handle shocks or vibration in your setup.
Do I need an indicator or an integrated package?
Integrated indicators simplify installation, especially for stand-alone systems. If you already have a weighing indicator or PC-based data logger, a standalone load cell with compatible outputs may be better.
Installation and mounting considerations
Check thread sizes and hole patterns on the ends for mounting flexibility. Ensure there are secure fixtures or rings to fix the sensor in place. Proper mounting reduces measurement error from misalignment or bending moments.
Output compatibility and integration
Ensure your controller or PLC supports the chosen signal type. If needed, plan for signal conditioning hardware to convert between mV/V and your system’s input range.
FAQ
- What is the accuracy of S-type load cells? Most listed options provide about 0.2% accuracy, ensuring precise readings across the stated ranges.
- Can these sensors measure both tension and compression? Yes, S-type load cells are designed for bidirectional force measurement in tension and compression.
- Which output should I choose? If you already have a PLC or DAQ that accepts 4–20 mA or 0–5 V, pick a sensor with that output. For direct bridge or instrumentation, mV/V is common.
- Is IP67 protection important? IP67 is beneficial in dusty or wet environments and where sensors may be exposed to immersion for short periods.
- Do I need an integrated display? An indicator helps quick setup and monitoring, especially in field or bench-top applications.
- What mounting considerations matter most? Ensure threaded ends and mounting holes align with your frame, and avoid placing the sensor where bending moments can occur.
