YO Refrigerant Monitor provides data on installation pressure. This information makes it possible to verify the correct functioning of the installation, as well as to prevent potential damage and the loss of materials and products that the installation maintains.

YO Refrigerant Monitor replaces the local pressure reading from an analogue sensor with a remote reading transmitted over LoRaWAN.

The device can be customised within the ranges:

  • pressure port (optionally available: 7/16-20 UNF female with depressor, 7/16-20 UNF male, 1/4-18 NPT, 1/8-27 NPT, G1/4);
  • pressure range, we offer 0-50 bar as standard
  • pressure type: gauge (as standard) or absolute pressure

The device communicates wirelessly over LoRaWAN. We are a certified member of the LoRa Alliance, which is responsible for data transmission security.
