PT-100/PT-1000 (RTD Type Temperature Sensors) - Roasting Intelligence Setup
Table of Contents
Since the Phidget 1046 is no longer sold in the Cropster store, we recommend the VINT Hub + TMP1200 for new installations.
If you are already using the 1046 setup, you can continue to use the instructions below for your configuration.
Specifications
Requirements
⚠️ Our shop-standard Cropster Connector is pre-configured with built-in resistors, eliminating the need for external components. If you purchase the Phidget 1046 from Phidgets.com directly, you will have to solder resistors to the sensor wire ends yourself to create a Wheatstone bridge.

Setup options
⚠️ Do not attempt to splice probe cables for dual-readout use. Splicing to connect both a physical machine display and the Roasting Intelligence data bridge simultaneously is not supported and will result in inaccurate data or connection loss.
Direct connection
- A direct connection applies when adding new probes independently of the roaster's readout.
- The newly added probe can be connected directly to the Cropster Connector.
Dual connection
- A dual connection applies when the roaster is equipped with a dual probe.
- A dual probe is a probe with two sensors inside the hull and two pairs of wires that allow a simultaneous connection to Cropster and the roaster's readout.
Cropster Connector installation
⚠️ Disconnect the USB cable from the VINT Hub and turn off your roast machine during the hardware installation.
-
Follow the probe cable from the tip of the probe to its end, where the wires appear.
In the case of dual probes, take the free end that is not connected to the roaster. -
Connect two leads of the temperature wires to any Cropster Connector channel with the provided screwdriver.
On the Connector, there are four channels for 4 temperature readouts: 0, 1, 2, 3. Each channel has four terminals. To connect the probe, always use the inner two terminals, marked with + and -. - Confirm your PT-100/PT-1000 RTD probe has more than two wires; please use only one red and one white wire.
- Leave all other cables disconnected and isolate them.
- Connect the Cropster Connector via the provided USB cable to your computer.
- Proceed with the Roasting Intelligence software setup.

Troubleshooting
If Roasting Intelligence indicates No source connected and/or you cannot see any measurements, please check the following:
- Is the Cropster Connector connected to the computer?
- Is the Phidgets driver installed?
-
Mac only: has the Phidgets driver been enabled in the Mac's Security & Privacy settings?
💡Good To Know:
If Roasting Intelligence shows negative temperature readings, you will have to swap the wires on the board from “G” to “0” (or 1, 2, 3) and the other way round.
