Which probes/temperature sensors does Cropster support
Overview
This article introduces the probes and temperature sensors supported by Cropster.
Cropster supports two types of temperature sensors:
- Ungrounded Thermocouples of the types J, K, T, and E
- Resistance temperature detectors (RTD) of the types PT-100 and PT-100
⚠️ Cropster only supports ungrounded sensors.
Ungrounded means that the junction (the point where the actual temperature is measured) does not touch the hull/sheath. An ungrounded thermocouple reduces the risk of ground loops.
When ordering from Cropster, you need to determine whether your roaster uses Thermocouples or RTDs. This is because the hardware and installation instructions they send you are specific to the type of sensor you have.

Can I keep my current temperature readout in parallel?
There are two ways to do this:
-
Splicing (Thermocouples only): Splicing means you connect the Cropster Connector (data bridge) with a two-wire cable (per logged temperature) in parallel to the corresponding channels of your current readout.
⚠️ Splicing does not work for RTD sensors. Splicing does not work on all roasters. If you get irregular or spiky readouts, please replace your probe with a dual probe. - Dual Probes: Dual probes carry two independent temperature sensors in one probe coating. Hence, each Dual probe carries at least 2x2 wires in one cable. After installing the probe, connect one pair of wires to your current readout, the other pair to the Cropster Connector.
