Custom- fabricated K-type thermocouples with extra length for MCR Series coffee roasters.
Armored stainless steel cable protects wiring protects from heat and electrical noise.
Direct M8mm mounted to securely hold the probe in place in high-vibration environments.
Sizes available with adjustable compression fittings to fine tune probe depth for different drum and batch sizes.
See notes below for additional information in size and installation.
Diameter x Length:
Thermocouple sizes are noted as (probe diameter) x (max. probe depth). The maximum probe depth is measured from the OUTSIDE of your drum door or drum face. See below.
Those thermocouples marked as “Adjustable” include a compression fitting behind the jam nut (shown above) that allows you to slide the fitting down the probe length and shorten the depth of the probe inside the drum.
Those thermocouples marked as “Fixed” will not be adjustable.
Thermocouples have M8 threaded cuffs for direct threading into thickness of drum door or drum face. If you are installing a thermocouple in a new location, you will need to create a M8 threaded hole to accept the threads of the thermocouple.
When installing thermocouples, we advise using the entire thickness of the door/face to engage as many threads as possible to create a secure fit. Once installed, tighten jam nut against outside of surface to further secure.
When installing with a Phidget 1048, red and green contact ends can be cut and wires stripped to insert directly into the phidget connection ports.
BT (Bean Temperature): Bean temperature is measured in the lower left of the drum where the bean mass piles during drum rotation. Typically on front face of roaster, often installed through the drum door.
ET (Environmental Temperature): Typically located opposite BT on right side of drum.
DT (Drum Temperature): Also sometimes referred to as the PID probe, this more centrally located probe connected to the PID controller which has the ability to turn the burner set on and off. Because if its central location, it is often a better gauge of the temperature of an empty drum and many roasters record their charge temps off of DT rather than BT.
IT (Incoming Air Temperature): Often located at the back face of the roaster.
