MODEL

Model 3580 Diametral High Temperature Extensometers - 33099 3580

High Temperature Diametral Extensometers Epsilon

Technology Corp

For transverse or diametral strain measurements attemperatures to 1000 °C (1832 °F).These extensometers may be used with furnaces having a side entry slot for an extensometer or with induction heating systems. They utilize a proprietary,rugged dual flexure design.

See the electronics section of this catalog foravailable signal conditioners and strain meters.

This model is for general purpose diametral strain measure-ment with furnace and induction heating systems. Quartz rods and water-cooling allow the unit to be used for high temperature testing of metals, ceramics and composites. With induction heating, this model often can be used without water-cooling.When used in furnaces, the extensometer is oftenmounted directly to the furnace side cut-out. Optional load frame mounting brackets are available for supporting the extensometer in cases where furnace mounting is not possible. These optional mounts are used with induction heating or furnaces systems.The Model 3580 extensometers are strain gaged devices,making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.

S PECIFICATIONS Excitation: 5 to 10 VDC recommended, 12 VDC or VAC max.
