Dc/Dc LVDT SX20MD series

High performance LVDT sensor- digital & analog outputs



  • Integrated digital electronics
  • Robust design and stainless steel housing
  • Error compensation
  • M12 connector
  • Digital RS485 and analog outputs


The Meggitt (Sensorex) SX20MD combines the advantages of LVDT technology (strength, reliability, contactless) with digital electronics.

The output signal, which is proportional to the core rod position, is available as both analog (0/10V and 4/20mA) and digital (RS485) in modbus protocol. All three signals can be used at the same time.

A digital hybrid module (HCN) is used to improve the sensor’s accuracy, notably the thermal drift and non-linearity.

This allows a non-linearity better than ±0.05% of full scale on the output signal.

Measurement range is from ±2.5mm to ±150mm.

Gauge head kit is supplied as standard (without spring return for stroke 300mm).


  • Monitoring and sounding of large structures
