Overview
The TS21 load cell is a strain-gauge-based sensor engineered for precision weight measurement in industrial settings. Its robust design caters to applications requiring durability, such as silo weighing, conveyor systems, and tank monitoring. As a widely trusted model, the TS21 balances cost-effectiveness with performance, offering capacities ranging from 100 kg to 50 tons. Its compatibility with most weight indicators and PLC systems makes it a versatile choice for automation integrations.
Structure and Working Principle
The TS21 employs a shear beam or compression design, where applied force deforms strain gauges bonded to a metal body. This deformation alters electrical resistance, generating a millivolt signal proportional to the load. Key structural components include a hardened steel or stainless steel housing, hermetically sealed electronics, and temperature-compensated circuitry. Some variants feature built-in overload stops to prevent damage from unintended forces.
Key Features
1. **Accuracy**: Typically achieves 0.03–0.05% of full scale, compliant with OIML R60 Class C3 standards. 2. **Environmental Resistance**: IP66/IP68 ratings protect against dust and water ingress; operates in -20°C to +60°C. 3. **Stability**: Low creep and hysteresis ensure consistent readings over time. Optional features may include explosion-proof certifications (ATEX) for hazardous areas or wireless connectivity for remote monitoring setups.
Application Areas
Primary industries utilizing TS21 sensors include: - **Food Processing**: Checkweighers and filling systems - **Logistics**: Truck scales and warehouse automation - **Manufacturing**: Force measurement in assembly lines Its modular design allows integration into custom solutions like hopper scales or multi-cell platform configurations, often requiring 3–4 units for balanced weighing.
Maintenance and Precautions
Regular maintenance includes visual inspections for physical damage and cleaning of load-bearing surfaces. Avoid chemical corrosion by selecting appropriate housing materials (e.g., stainless steel for washdown environments). Electrical checks should verify cable integrity and shield grounding. Recalibration every 6–12 months is recommended, or after mechanical shocks. Always use torque-limiting tools during installation to prevent overtightening.
B2B Procurement Guide
1. **Specification Matching**: Confirm required capacity, accuracy class, and environmental ratings. 2. **Supplier Evaluation**: Prioritize manufacturers with ISO 9001 certification and traceable calibration reports. 3. **Cost Factors**: Bulk orders (10+ units) often attract 15–20% discounts; compare lead times for OEM vs. distributor channels. For custom requirements (e.g., special cable lengths or connectors), provide detailed technical drawings early in the RFQ process.
