The Model 4030 extensometer uses a special LVDT-like sensor to measure strains on samples submersed in water or other compatible liquids. The unit is provided with the signal conditioning electronics. The extensometer is a semi-custom design, which is available in smaller measuring ranges up to 5 mm (0.2 inches). Clip-on (COD) style designs are also available.
These are made entirely of stainless steel with Teflon cables. They can also be supplied with ceramic knife edges and heat shrink tubing over the quick attach kit wires, to eliminate any galvanic corrosion issues with test samples.
• Signal conditioner and power supply included. Easily interfaced to test controllers, data acquisition boards, and chart recorders.
• Shipped fully calibrated with electronics (traceable to NIST) with user specified voltage output.
• Includes high quality foam lined case.
