Strain gauge bundle supports high-temperature applications
The gauges are optimized for a wide variety of hostile environment applications, including geothermal measuring equipment, turbine engine control, and environmental test chambers in military, industrial, automotive, and down-hole drilling systems. Many analog circuits in these applications require components such as strain gauges capable of surviving temperatures up to +1150°C.
The bundle is offered with a choice of two strain gauge series: ZC-Series free-filament strain gauges with etched Kanthal foil alloy grids and weldable
LZ-Series wire strain gauges with Nichrome V and Pt8W alloys. Installation options for the ZC series include GC, H, PBX, and Sauereisen DKS-8 ceramic cements, and lead wire options include spot-welded Nichrome V ribbon in widths of 1.6 mm and 3.2 mm and with thicknesses of 0.05 mm and 0.08 mm, respectively. The LZ series has two pre-attached leadwire options: M (Inconel tubing) and F (fiberglass insulation).
For weldable strain gauges, the bundle includes the Model 700 Portable Strain Gage Welding and Soldering Unit with continuously adjustable weld energy from 3 J to 50 J. An available addition, the 2200 Signal Conditioning System provides constant current excitation, typically required for high-temperature measurements, and precise conditioning of strain gage inputs in the most severe high-temperature operating environments. The bundle comes with technical guidelines and is backed by support from the technical experts at Micro-Measurements.
