Multichannel Temperature Sensors

The FDA Food Code 2001 for temperature measuring devices requires accurate temperature sensing to ensure the quality of foodstuffs during transport and storage. Applications such as commercial refrigerators, freezers and transport vehicles require temperature accuracy at low temperatures.

The MCP9902/3/4 , a multi-channel low-temperature remote diode sensor, offers the required accuracy (±1°C) to maintain cooler temperatures for quality foodstuffs. The key features of the MCP9902/3/4 are:

  • Maximum error of ±1°C from –40°C to 105°C
  • Automatic beta detection
  • Resistance Error Correction (REC) up to 100Ω
  • Programmable temperature limits
