Easiest Way to Get Data on the Cloud

The OleumTech® Sigfox Ready SFX-TC51 Wireless Thermocouple Transmitter is designed for deployment anywhere in the world that Sigfox has network coverage. By leveraging the Sigfox Low Power Wide Area (LPWA) network, you can take advantage of the world’s leading Internet of Things (IoT) connectivity service, offering a software-based communications solution where all the network and computing complexity is managed in the Sigfox CLOUD™.

Inherently Secure

The OleumTech Sigfox wireless IoT devices take advantage of the built-in firewall since they are not directly connected to the internet and do not use Internet Protocol. Layered on top of this secure foundation, OleumTech provisions each device with a unique symmetrical authentication key. Each message sent by the node contains a cryptographic token that is computed based on this authentication key and verified by each Sigfox Base Station.

Designed for Hazardous Locations

The SFX-TC51 wireless sensor node is certified for use in Class I, Division 1 (Zone 0) hazardous locations. It is intrinsically safe, designed not to cause a spark, and can be serviced without being removed from a process. The SFX-TC51 is designed for integration with a third-party J or K-type thermocouple sensor.

Extremely Reliable

The Sigfox architecture is based on multiple base stations receiving each broadcasted and repeated message, building redundancy into the solution. Data Integrity, availability, and confidentiality are at the core of the offering.
