Diedrich (with sensor package) - Roasting Intelligence (RI) Setup

This manual covers the connection of Diedrich roast machines with pre-installed sensor package to Cropster's Roasting Intelligence.


The following article and its screenshots refer to the Roasting Intelligence (RI5). 

In case you previously used the Roasting Intelligence (RI4) we kindly invite you to check the newly improved features of RI5. 

To upgrade to RI5, please download the Roasting Intelligence (RI5).


  • Sensor package (or Phidget 1048) pre-installed
  • USB cable

Preinstalled Phidget

There are 4 different setups:

  • 3-sensor-setup: Bean, Inlet, and Drum
  • 4-sensor-setup: Bean, Inlet, Drum, and Exhaust
  • 5-sensor-setup: Bean, Inlet, Drum, Gas, and Airflow
  • 6-sensor-setup: Bean, Inlet, Drum, Exhaust, Gas, and Airflow

Locating the Phidget 1048

To accurately configure your Diedrich's connection in the Roasting Intelligence (RI), we recommend that the preinstalled Phidget must be found inside the machine. 

The location of the Phidget may vary from machine to machine.

For reference, please refer to pictures of the Phidget, taken from inside of Diedrich roast machines.

    Identifying the temperature measurements

    Next, we recommend that you identify, and label the probes by measurement (e.g. Bean temp, Inlet temp, etc.). Simply, follow the cables for each probe; from the tip of the probe to its end, where the probe connects to the Phidget.

    Once the Phidget has been located, and labeled, we recommend to take pictures of the Phidget, for later reference when establishing a connection to the machine.
