Model 340

The force transducers of the model series TesT 340 use a proprietary sputtered thin film strain gauge technology to create a rugged sensor with exceptional long-term stability. The compact sensors with their simple beam mounting configuration can be used to electronically measure force in a wide variety of applications. These highly sophisticated load cells are manufactured in high quantities, using state-of-the-art equipment. Customised characteristics can be provided for high volume purchasers.

Electrical Force Transducers – Model 340

  (Installation inside plug)

The electrical force transducers of the model series 340 work by using a sputtered strain gauge technology and thereby they reach a high accuracy. They are characterised by their flat design with very small dimensions, as well as by their high long term zero point stability and their low hysteresis. The highly sophisticated force transducers are excellently suitable for tensile and compressive measurements in very small measuring ranges. Applications: Medical instrumentation, force, displacement and acceleration measurement, robotics, food dispensing equipment.
