Oct 14, 2010 Based on fiber Bragg gratings, Model K-OR uses light to measure strain instead of electrical signals. Unit comes in rosette form comprising 3 measuring grids at angles of 0, 60, and 120° to sense strain as it occurs, allowing absolute value and direction of mechanical stresses to be defined. Measuring 43 x 47 mm, K-OR enables tests of up to 10 million load cycles with strain of ±5.000 µm/m. Unit is suited for potentially explosive atmospheres and areas where there is high voltage or EMI.

Feb 19, 2010 Based on fiber Bragg gratings, K-OP type optical strain gage (SG) suit material tests of new fiber composites. Tests with up to 10 million load cycles with alternating strain of ±5.000 µm/m are possible. As no electric signal is required, utilization in environments with explosive atmospheres, EMI, or high voltage is possible without difficulties. Several optical SGs can be attached to fiber, enabling implementation of parallel measurements.

Mar 11, 2009 At 1.2 x 2 mm, Y series micro-strain gauges detect mechanical stresses that occur during production of complex PCBs. They attach directly to board to monitor levels, which are 850 µm/m for unpopulated PCBs and around 450 µm/m for populated boards. Measurements can be obtained during production processes including depanelization, plug assembly, in-circuit testing, and installation as well as in solder bath. Units are available in linear and rosette form.

Feb 18, 2004 High-Temperature, Weldable Strain Gages are free-filament wire units pre-bonded to shim stock with flame-sprayed alumina. Bonded wire design resists fatigue, making gages suited for dynamic, impact, or vibratory strain measurements. Devices come with choice of Nichrome V or Pt8W sensor alloys and either of 2 types of pre-attached, high-temperature, insulated cable. All feature nominal resistance of 120 ohms and sensor gage length of 0.25 in.

Aug 07, 2002 AP815, for single strain gages, allows connection of quarter bridges in 4-wire circuit, and half and full bridges in 6-wire circuit. With half bridges, card allows active and compensation strain gages to be arranged separately, and corrects voltage loss at connecting line. Five excitation voltages are available, providing measuring range of 8 to 80 mV/V and 0 V listening mode to assess line noise. Internal shunt resistor per channel is switchable upon user demand.

Nov 19, 2001 AP810 card allows 8 strain gauge half or full bridges to be connected in regulated 6-wire circuit. Excitation points are equipped with sense lines so cable effects are fully compensated. All 8 channels operate simultaneously, so there is no scanning and no multiplexing. Card has digital filtering for synchronous channel operation. Bessel and Butterworth filters are available, and measurement frequency is variable between 0.05-500 Hz.
