Sense Fit 400

The Sense Fit 400 is a small form factor, battery free RFID tag with built in temperature sensor. Its small size makes it ideal for a number of applications where space is tight or limited intrusion is desirable but this does not affect performance as the read range is up to 4 meters. An ideal solution when space is limited but both RF performance and operational environment information are required.


A small form, high RF performance device with accurate temperature monitoring, ideal for applications requiring:

  • Efficient operation
  • Equipment monitoring in-house or in transit
  • Data Centers and metal IT assets – both in terms of tracking and temperature monitoring
  • Embedding the tag into metal components
  • Monitoring mechanical plants
  • Predictive maintenance
