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
