Concrete maturity temperature sensor

Concrete temperature and maturity with Type K thermocouples

Maturity temperature sensor

Orbit K is rugged wireless temperature sensors for concrete maturity and strength monitoring and documentation. You simply mount the thermocouple in the concrete form work (attached to the rebar in the concrete) before pouring. Simply start measuring by connecting the connector to the Orbit K and you will now be able to remote monitor your concrete maturity in real-time. New data will be measured every 10 minutes and transmitted wireless without use of local devices to the cloud, where temperature, maturity and strength data will be available in reports

True remote monitoring

One of the challenges about monitoring concrete with wireless sensors is to collect the data. We have designed our sensor for what we call true remote monitoring. With this we mean that you do not have to once in a while to walked around to all your sensors and collect your data from your different sensors.

With our concrete sensors you will see data is sent directly to the cloud without any additional use of devices. This means you can be monitor concrete at once place while you are located far from the concrete.

Real-time temperature & strength calculations

Everything we do is in real-time. Data is as a standard gathered every 10 minute and calculated for you into maturity and strength. The time from taking the measurement until it is ready in your report is a matter of a few seconds – this is what we call real-time.

Affordable concrete sensing solution

The Orbit K is an enable to move the concrete monitoring with thermocouples into 2018 powered technologies. The thermocouple method has showed for several decades to be a reliable or proven method to document concrete. The only challenge has been that it were usually only used for documentation with traditional data loggers – and thereby not would be able to utilize the benefit of wireless real-time monitoring.

The Orbit K enables you to easy move to a cloud and digital solution for concrete monitoring using the solution you already know and rely on today – the thermocouples.

* The tolerance of the external temperature sensor depends on the type K thermocouple in use. Standard are around ±2.2 °C.
It is possible to purchase higher quality thermocouples with better precision. For further information feel free to contact us

** Dependent on the type K thermocouple.

*** Battery life depends on mode, operating temperature, and frequency of measurements and transmissions. Standard configuration gives a lifetime of 1-2 years (estimated based on tests and simulations).

**** RC1 is Sigfox Ready certified with Class 0. RC2 and RC4 is pending certification and are currently available as samples.
