Well Dimensions
   Stem Length:       Length from bore to end of well, be sure to consider the length required to pass through walls, pipe fittings etc. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Socket/Stem Insertion Length:       The distance from the end of the well to the underside of the thread, or other connection means, also know as "U" dimension. The length should be long enough to permit the entire temperature sensitive part of the sensing element to project into medium being monitored. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Bore Diameter:       The selection of proper bore diameter allows the same well to accommodate various temperature sensing devices. Typical values are .260 or .385. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Length of Lagging Extension:       Length is the distance from top of connection means (i.e. thread) to bore. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.
   Operating Temperature:       The temperature range over which the device must operate. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Lagging Extension?       Lagging extensions take into account the insulation, pipe fittings, walls etc, through which a sensor may pass. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Material of Construction
   Material of Construction      Materials can determine a thermowell's longevity. Consult manufacturer for exact material specifications, as proper material selection impacts well strength, corrosion resistance and temperature sensitivity.
   Your choices are...         
   Alloy Steel       Consult manufacturer for exact material specifications. 
   Aluminum       Consult manufacturer for exact material specifications. 
   Brass       Consult manufacturer for exact material specifications. 
   Carbon Steel       Consult manufacturer for exact material specifications. 
   Copper       Consult manufacturer for exact material specifications. 
   Hastelloy® B&C       Consult manufacturer for exact material specifications. 
   Monel       Consult manufacturer for exact material specifications. 
   Nickel       Consult manufacturer for exact material specifications. 
   Stainless Steel       Consult manufacturer for exact material specifications. 
   Tantalum       Consult manufacturer for exact material specifications. 
   Titanium       Consult manufacturer for exact material specifications. 
   Other       Other unlisted, specialized, or proprietary materials of construction. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Coatings:       
   Your choices are...         
   Teflon® Coated       Coatings can allow the well to be used in various environments. 
   Tantalum or Titanium Jacket       Coatings can allow the well to be used in various environments. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Connection Options
   Connection Means:       
   Your choices are...         
   Socket Weld / Weld In       The thermowell is welded into existing process components, provides good seal. 
   Flanged       The thermowell is flanged and connected via bolts into existing process components. Provides strength and seal. 
   Van Stone       An internal type flange that withstands high pressure within a chamber and will prevent the thermowell from "blowing" out. This type of connection requires access into the existing process components 
   Threaded       The thermowell is threaded and is secured via a screwing motion into existing process components. Provides strength and seal. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Thread Options:       
   Your choices are...         
   1/2" NPT         
   3/4" NPT         
   1" NPT         
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Barrel or Shank Style
   Barrel or Shank Style       
   Your choices are...         
   Stepped Shank Well       Stepped shank permits smoother velocities around well and increased sensitivity. 
   Straight Shank       Usually more cost effective due to no extra machining required. 
   Tapered Shank       Increased sensitivity like stepped, but with greater stiffness. Permits higher fluid velocity. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Options
   Cap and Chain       The cap works as a plug to keep the thermowell clean when the well is not in use. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   3A Sanitary Approval Stamping       3A Approval stamped on well. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Sanitary Design       Designed for sanitary applications. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
