Easiest Way to Get Data in the Cloud
The OleumTech® Sigfox Ready SFX-RT51 and SFX-RT52 Wireless RTD Temperature Transmitters are 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 Sigfox Ready Transmitters 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 transmitter contains a cryptographic token that is computed based on this authentication key and verified by each Sigfox Base Station.
Designed for Use in Hazardous Locations
The SFX-RT51 and SFX-RT52 are certified for use in Class I, Division 1 (Zone 0) hazardous locations. They are Intrinsically Safe, designed not to cause a spark, and can be serviced without being removed from a process. The SFX-RT51 is a direct mount type that is available with a 4-wire Platinum 100 ohm Class A RTD sensor. The SFX-RT52 is designed to support a third-party RTD sensor: 2, 3, or 4-wire type.
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.
