These extensometers use a high température capacitive sensor in combination with an innovative design to achieve high accuracy strain measurements in low measuring ranges not possible with other high température extensometers. They mount on a slide bracket (included) that can attach to the load frame of your test System; optional load frame mounting brackets are available. The overall design reduces any influence from common lab environment vibrations.
The standard température version (to 1200°C) is supplied with high purity alumina rods. The high température option is furnished with alpha grade Silicon Carbide rods. Rods are made to order to the length required for your furnace. These units are made to order in many different gauge lengths and measuring ranges.
The extensometer cornes with a signal conditioner. The output is an analog DC voltage, factory calibrated with the extensometer to 0 to ±10 VDC typically. They are readily interfaced with most existing test controllers, and may be directly connected to data acquisition Systems and chart recorders. Bringing the signal into a spare DC input channel (or external input) on the test controller allows the extensometer to be used for strain controlled tests like low cycle fatigue.
