Key Features Heading

All the FSI units supplied by Epsilon Optics offer the following key advantages:

  • Rugged and reliable having been designed for tough environments including high vibration, electro-magnetic noise, power dips and large variations in temperature and humidity.
  • Insensys TDM technology – greatly simplifies the design of sensor arrays allowing full measurement range for every sensor.
  • Long term accuracy and reliability.
  • Low power consumption makes it suitable for remote locations and mobile platforms where mains power is intermittent or not available.
