WIKA TH2R025BR Brass Threaded Thermowell Reduced Shank, 2.5" "U" Dimension, 1/2" NPT Process Connection for Bimetal and Gas Actuated Thermometers

Model: 50TH2R025BR   |    Mpn: 50TH2R025BR   |    PartNumber: 50TH2R025BR   |   Asin: B005P16JN6

Application Thermowells for temperature instruments are recommended for all process systems where pressure, velocity or viscous, abrasive and corrosive materials are present individually or in combination. A properly selected thermowell will protect the temperature instrument from possible damage resulting from these process variables. Furthermore, a thermowell permits removal of the temperature instrument for replacement, repair or testing without effecting the process media or the system. Process Connection: External means to connect thermowell to process piping system. Wells can be threaded, bolted (to matching flange), clamped or welded in place. Bore Diameter: Dimension of internal bore to match the diameter of the instrument stem/bulb inserted into the well. The 0.260" sizes fit instrument stem/bulb diameters of 1/4" and 3/8" respectively. Bore length equals "S" dimension. Reduced Shank: Also called reduced tip. The shank OD is reduced over the last 2-1/2" of the "U" dimension from the standard root diameter to a 1/2" OD.

Features

  • Process connection: Threaded
  • Shank configuration: Reduced
  • Bore diameter: 0.260
  • Surface finish: Brass: 60-100 Ra, AISI 304 and AISI 316: 60-100 Ra
  • U Dimension: Length of well inserted into the piping system, measured from the base of the process connection to the end tip of well

Model: cbtw   |    Mpn: cbtw   |    Ean: 0885879178896   |    PartNumber: cbtw   |   Asin: B00SYNDFSE

This carboy thermowell is used in conjunction with the digital thermostat to more accurately regulate internal temperature during fermentation. It is exceptionally useful during the start of fermentation when the lag between ambient temperature in the refrigerator and actual temperature in the carboy can vary greatly. Now you can keep your beer or wine within one degree of the set point on your digital controller. Designed to fit either the 5, 6 or 6.5 gallon glass carboys, or any other similarly sized opening hole, the unit comes with an 15' stainless steel thermowell and a 6.5 stopper. It can be used in any container with a stopper opening where you need to accurately monitor and control liquid temperature. You can use this with your refrigerator for exact cooling temps, or use it with one of our heating products to control how warm your fermenter gets.
