Epsilon Technology Corp. High Temperature Furnace Axial Extensometer Model 3548HI

Designed to allow the gauge length to be set prior to mounting on the test specimen, this model allows hot mounting on samples after they reach the test temperature. These extensometers mount on a slide bracket (included) that attaches to the furnace side cut-out or with other support brackets; optional load frame mounting brackets are available. The gauge length for this unit can be set prior to mounting on the specimen, which allows mounting on specimens after they are heated to the test temperature. Water-cooled and furnace bracket mounted, they are for use in split type materials testing furnaces to 1200 °C (2200 °F). The high temperature option allows use to 1600 °C (2900 °F). These extensometers can be used in carousel systems for rapid high temperature testing. The standard temperature version (to 1200 °C) is supplied with high purity alumina rods. The high temperature option is furnished with alpha grade silicon carbide rods. Rods are made to order, to the length required for your furnace. Mounting brackets may be integrated with the furnace cut-out. Epsilon can also provide load frame mounting brackets to fit your test frame. The Model 3548HI 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.
