Customize Readout with Non-Linear Table The table function used in the Tap Position Indicator is adaptable to a variety of non-linear applications. A sensor with a non-linear output can be corrected using one of the 32 point tables in the Premo Bargraph meter. Data on up to 4 sensors can be stored in memory or the tables can be cascaded for precise 128 point correction of a single sensor. Tank level is another popular use for the table function. Level in an irregular shaped tank does not indicate the amount of fluid in the tank... (read more)Browse Digital Panel Meters Datasheets for Weschler Instruments
Curvilinear Rails for Nonlinear Special Movements Curviline is the name of the curvilinear rail product family. They are used for all non-linear special movements. Rails with constant or variable radii may be specified according to customer requirements, resulting in a highly flexible, economical solution. Curviline is available in two rail widths. The use of standard radii is recommended. All non-standard rail layouts and radii are possible as custom products, however extra lead time may result. The most important characteristics: Straight...

649 Spindle Square The Starrett 649 Series Spindle Square offers accuracy, convenience and significant time saving with the task of tramming the head of a vertical milling machine. This must be done regularly to ensure squareness and perpendicularity between the spindle and work surface. The spindle square is easier to use and more precise than the traditional method of tramming with a dial test indicator. Features & Specifications. • Fully assembled with two AGD Group 2 dial indicators. •... (read more)Browse Squares Datasheets for Starrett

Square and Rectangular cartridge heaters Features. The Hotwatt Square and Rectangular Cartridge Heater is designed to distribute maximum heat within a desired area. Because they are completely enclosed, square units will furnish more usable heat for a given wattage than a comparable strip heater attached to the exterior of a mod, platen, or other equipment. The units are inserted in a milled slot, permitting greater lengths than would be feasible with a drilled or reamed hole. Close dimensional tolerances are held to permit intimate...

Robvon Backing Ring Company, Inc.
Square Weld Rings Are Squings Robvon Squings are designed for quick, easy alignment of square or rectangular tubing and to assure a precise, close tolerance fit-up. They allow complete penetration and fusion of the weld. The patented nubs automatically set the weld gap for the root-pass. The Robvon Squing eliminates the necessity of tack welding and it also eliminates slag, icicles or metal inside of the tube. Squings are available in all the standard materials Robvon offers. Other material available upon request. To learn... (read more)Browse Welding Accessories Datasheets for Robvon Backing Ring Company, Inc.
