Siemens SIWAREX FTA, FTC, and WP251 Dosing and Batching Controllers
Siemens SIWAREX FTA, FTC, and WP251 controllers perform high-speed automatic dosing, batching, bagging, and continuous belt weighing. They hold OIML R-76, R-51, and R-61 legal-for-trade approvals. Complete integration into PCS 7 ensures accurate multi-component material flow control.
- Operating modes compliant with OIML R-76, R-51, and R-61 for trade-approved scales
- Integrated coarse and fine dosing algorithms for liquid and bulk material feeds
- Continuous flow rate and belt speed calculation in SIWAREX FTC scale processors
- Preconfigured library function blocks and HMI faceplates for TIA Portal projects
Siemens SIWAREX WL230, WL250, WL260, and WL270 Precision Load Cells
Siemens SIWAREX WL precision load cells cover rated capacities from 3 kg to 500 tons for hopper and platform scales. Fabricated from stainless steel with IP68/IP69K sealing, WL230, WL250, and WL270 models withstand washdown plants. Class C3 rating ensures high measurement repeatability.
- Rated load capacities ranging from 3 kg up to 500 tons for tanks and platforms
- Class C3 and C4 accuracy ratings according to OIML R-60 temperature standards
- Stainless steel laser-welded construction delivering IP68/IP69K ingress protection
- Intrinsically safe configurations for ATEX Zone 1/2 hazardous atmospheres
Siemens SIWAREX WT231, WT241 Terminals and SIWAREX DB Digital Junction Boxes
Siemens SIWAREX WT231 and WT241 stand-alone weighing terminals feature a 4-inch color touch panel and Modbus RTU communication for autonomous operation. Digital junction boxes SIWAREX DB deliver individual load cell diagnostics. The system detects wire breaks and bridge imbalance instantaneously.
- Autonomous WT231 and WT241 terminals equipped with 4-inch color touch screens
- Digital junction boxes SIWAREX DB for single-channel load cell defect diagnostics
- Instant detection of cable wire breakages and bridge circuit impedance drift
- Connection of up to four strain gauge load cells per channel via RS485 link
Industrial Weighing Electronics Portfolio of Siemens SIWAREX
Siemens SIWAREX industrial weighing electronics include technology modules WP231, WP321, WP351, dosing controllers FTA/FTC, and heavy-duty strain gauge load cells WL series.
Engineered for hopper scales, automatic dosing units, high-speed bagging machinery, belt weighers, and continuous material flow systems, this hardware delivers extreme reliability across process plants.
Every weighing module integrates directly into SIMATIC S7-1200, S7-1500, and ET 200SP controller racks, providing millisecond digital output response times, integrated web servers for diagnostics, and legal-for-trade verification compliant with OIML standards.
Engineering Selection Criteria for Weighing Processors and Load Cells
Selecting Siemens SIWAREX weighing equipment requires defining the weighing application type (static platform, dynamic continuous belt, or high-speed bagging), required legal-for-trade certification, and SIMATIC controller platform.
Static level monitoring in tanks and platform scales typically utilizes WP231 and WP321 modules matched with WL230 bending beam or WL250 S-type cells.
High-speed batching and filling applications benefit from WP351 technology modules with 1000 Hz conversion rates or SIWAREX FTA processors, whereas continuous conveyor flows are governed by SIWAREX FTC or WP241.
SpareX application engineers calculate load distribution and specify mounting accessories with lift-off protection.
