The SI 750's exceptional reliability is a result of manufacturing processes and assembly techniques developed and optimized by Macro Sensors over many years of manufacturing LVDT sensors.  Their stainless steel housings act as magnetic shields to reduce the effects of external AC magnetic fields, and their sealing meets IEC standard IP-62. Available in standard ranges of 1 inch (25 mm) to 20 inches (500 mm), the maximum linearity error for an SI 750 Series sensor is ±0.25% of full range output using a statistically best-fit straight line derived by the least squares method. 


  •  Standard measurement ranges of 1 to 20 inches
  • 4 to 20 mA input/output
  • Non-linearity of ±0.25% of FRO or better
  • Industry-standard 3/4 inch (19 mm) diameter
  • Through-bore design
  • Sealed to IEC IP-62
