Well Dimensions
Back to Top
|
| ||
| 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. | ||

|
|
| ||
| 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 | |||
| 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. | ||
