LDS sensors are available in two types, the LDS which has an outer case Ø17.4 and the LD20 with an outer case Ø19.0, displacements range from 5mm through to 100mm. For technical information see the Specifications page for performance data and dimensional sizes. Both ranges of sensors have sprung return stainless steel outer case and are fitted with a 2 metre flying lead.


• ENGINEERED FOR QUALITY

LDS sensors rugged construction, low force spring return spindle, utilising low excitation voltage, light current consumption and strain gauge sensor compatibility are all key design factors coupled with modern production techniques of this precision engineered sensor that offer the customer a robust and consistent quality product.


• ACCURACY

LDS sensors produce proportional voltage output in relation to the captivated guided spindle displacement via the four active arms of a 350 ohm strain gauge bridge arrangement. This fully active bridge provides excellent temperature compensation characteristics coupled with true output linearity.


• COMPATIBILITY

LDS sensors belong to the family of strain gauge sensors and exhibit the same inherent advantages for linearity, resolution and versatility as such they are systems compatible with a wide range of commonly used sensors for load, pressure, acceleration, vibration etc. utilising a millivolt signal for most off the shelf instrumentation.


• VALUE

LDS sensors compatibility with low cost instrumentation, providing higher accuracy test data, reliable feed back and control, yields greater value in wide variety of applications, industrial process control, civil engineering projects, soil mechanics, R & D testing, automotive and aerospace etc.
