DMS Digital Fibre Optic Displacement Sensor

These sensors provide a linear distance output with RS232 or USB communication. Dynamic light signals reflected from target surfaces are converted to distances by comparing the sensor signals to gap calibration tables stored on-board the sensor. The digital sensors have the added simplicity of providing a linear output for the full operating range of the sensors.

DMS Sensor - RS232 Outputs directly to PC/PLC with a build on LCD display. Max output rate of 5208 samples/second with a possible max two channels.

mDMS Sensor - RS232 Output directly to PC/PLC with a max output rate of 5208 samples/sec

muDMS Sensor - Smallest possible sensor with USB output directly to PC/PLC and a max output rate of 16 000 samples/second.

 

Bluetooth for all RS232 DMS sensors

  • Fibre optic principle means complete insensitivity to magnetic fields and high voltage electrical fields; can therefore be used where inductance or capacitance sensors do not work
  • Rugged construction; suitable for all types of difficult environments such as vacuum, high pressure, cryogenic temperatures, high temperature, in fluids or explosive atmospheres
  • Linearised output for the full operating range of the sensor
  • DMS Control Software includes a data averaging filter for averaging data samples from 2 samples, (the fastest rate), to 4096 samples, (highest resolution)
  • Rotor runout
  • Thermal growth
  • Distance of glass
  • Displacement in fluids
  • Actuator stroke
  • Diaphragm deflection
  • Read/Write head tracking
  • Solenoid travel
  • Measurement in vacuums in cryogenic temperatures
  • Compressor blade vibration
  • Shock testing
  • Thread inspection
