Long temperature sensor for mounting in kettle or fermenter wall. NPT thread.


This sensor has been designed specifically to mount it in a kettle of fermentor wall. With our sealing locknut, it is easy to install and it is watertight.
This sensor has a DS18B20 OneWire sensor inside with a detachable cable. It is a perfect replacement for a thermowell and separate sensor.

This is the NPT version (thread used in the U.S.A.). A BSP version is also available.

Ideal for mounting in:

  • Plastic fermenters
  • Conicals
  • Kettles (HLT, BK or mash sensor)


  • Plug and play with the BrewPi Spark
  • Maxim DS18B20 sensor
  • RJ11 plug (fits in RJ12 socket)
  • 2m silicone detachable cable

  • Stainless steel SS304
  • Probe length 60 mm / 2.4 inch
  • Thread type: 1/2" NPT
  • Thread length: 9 mm / 0.35 inch
  • 0.0625 ºC resolution
  • Range of -55°C to +125°C
  • Factory accuracy of ±0.5°C over the range of -10°C to +85°C
  • With calibration via the BrewPi software, accurate to 0.0625 °C


If you buy this sensor to mount it inside a threaded port, make sure you pick the correct version (NPT/BSP).

To make a hole in your kettle, use a 21mm hole punch.

Warning: not compatible with other PID controllers, like the STC-1000. These devices need an analog thermocouple sensor. This is a digital OneWire sensor.
