SNR-T220 | Wireless Thermocouple Sensor

Wireless Thermocouple Sensor

The MSG Wireless Thermocouple Sensor is available with a hardwired thermocouple or K-type connector to support various thermocouple types and ranges. The hardwired thermocouple option measures temperatures up to 400°C (752°F). The K-type connector with Probe includes a needle probe that measures temperatures up to 400°C (752°F).  Users have the ability to set the frequency of readings, set thresholds for alerts and to send alerts via SMS text and/or emails. Sensor conditions and readings are transmitted and displayed to a web and mobile accessible Dashboard via Cellular or Ethernet Gateways.

Suggested Applications & Use Cases
  • Ovens and cooking device monitoring
  • Food Temperature Monitoring
  • Chimney and Flu Temperature Monitoring
Product Features
  • Superior Range: Offer 3 to 4 times the range of standard sensor platforms, extending non-line-of-sight reach to an exceptional 1,200+ feet through walls (12-14 walls typical).
  • Long Battery Life: Advanced power management provides 10+ years
  • Secure Wireless Communications: Encrypt-RF® Security for all sensor data messages, maintaining security at all communication points.
  • Data storage: Integrated on-board data storage allows sensors to store data messages if communication to a wireless gateway is disrupted (power outage, Internet outage, or out of range).
  • Over-the-air updates allow products to be updated remotely if new fixes or features become available.

* Actual range may vary depending on environment.
