Model 307

The electrical force transducers of the model series TesT 307 with classic S-type shaping are often used when cramped spaces and high standards occur at the same time. These sensors which are made of high-quality aluminium are lightweight and well suitable for tensile and compressive measurements that pass through the zero-point. Special versions are available on request, which achieve class 0,5 according to ISO 376 and can be employed for calibration purposes in QA systems. The sensors 307 are available in two different design sizes.

Electrical Force Transducers – Model 307

• Capacities: 20N to 500N (I)
• And 1kN to 25kN (II)
• For compression and tension
• Stainless steel / Aluminum
• Highest accuracy
• Also as calibration version
• Reference transducer up to 2kN
• Sensitivity: 2mV/V
• TEDS module (inside sensor)
• With threaded connector

The electrical force transducers of the model series 307 are suitable for compressive and tensile measurements. The sensors that are made of stainless steel or aluminum (depending on capacity) are available in two sizes. They are suitable for static applications as well as for slightly dynamic applications while a TEDS module is already integrated inside the devices. On demand you receive the model 307 in version Cl. 00 which achieves class 00 according to ISO 376 and is used for calibration purposes.
