Showa Measuring Instruments WBJ Tension & Compression Load Cells
Made in Japan
Manufacturer: SHOWA MEASURING INSTRUMENTS Co., Ltd.
Model: WBJ
Features
- Covering the minute capacity range 0.2 to 2N.
- Using special designed 350Ω strain gages for the detection of load, thereby, an excellent linearity or thermal coefficient of 0.035%R0 can be attained.
- Attractive load charactetistics in maximum overload (200%RO) and in side load (30%).
- Guaranteeing the load leaving off coefficient up to 2.5 cm maximum.
- A specially designed mounting table (Optionally supplied) can be utilized as a measuring unit.
