Model 303

The electrical force transducers of the model series TesT 303 are often used when cramped spaces and high standards occur at the same time. These sensors, which are made of stainless steel, are suitable for measuring tensile and compressive forces.

Electrical Force Transducers – Model 303

• Capacities: 1kN to 10kN
• For compression and tension
• Stainless steel
• Small dimensions
• Sensitivity: 2mV/V
• High accuracy
• For dynamic applications
• TEDS Module possible

The electrical force transducers of the model series 303 are excellently suitable for cramped space conditions because of their small dimensions. Due to their low measuring uncertainty they meet also under ambitious requirements. The force transducers, made of stainless steel, are used for compressive forces as well as for tensile forces. The integration of a TEDS module inside the plug is also available on demand.
