Now in its fourth generation, the Loom Laser series Thread-Break Detection system uses cutting-edge laser and microprocessor technology to provide protection from thread breaks in any weaving environment.
Thread breaks are detected when the CPU senses small changes in the light received by the photocell (receiver). The system is programmed to differentiate between actual thread breaks and false signals generated, for example, when a dust particle or an insect passes through the beam.
Lasers can be strategically placed at critical points-the whiproll, back shed, front shed, or on the lay-to give complete thread-break coverage.
The advanced capabilities of the LL-2000 Loom Laser can detect threads as small as 30 microns on looms operating between 120 and 600 rpm. At the same time, the system is immune to changes in ambient light, and can withstand vibrations up to 14mm in amplitude at the surface of the receiver sensor.

The OBR 4400 takes the industry's first ultra-high resolution OTDR with backscatter-level sensitivity designed for component- and module-level reflectometry to the next level. With a small, easily transportable platform, the capability to "see" reflections out to 2 kilometers with no dead zone, and integrated temperature and strain sensing, the OBR 4400 gives you the ultimate in fiber diagnostics. The OBR 4400 uses swept-wavelength coherent interferometry to measure minute reflections (< 0.0003 parts per billion) in an optical system as a function of length with spatial resolution less than 50 microns. This provides the user with precision reflectometry and unprecedented optical-module inspection and diagnostic capabilities by providing the ability to locate and troubleshoot splices, connectors, fiber bends and breaks, insertion loss points, track polarization, verify PM components and more.

The ground resistance of substations can be measured with two auxiliary electrodes which are put into the ground. To avoid influences from the mains current and its harmonics, this measurement should preferably be carried out with 128 Hz.The high output power of the CPC 100 ensures a high ratio of the signal level to the noise level. Thanks to the signal processor technology, the measuring procedure is very selective and disturbances by ground currents are reduced to a minimum.

3731 Clamp-On Ground Resistance Testers
The Clamp-on Ground Resistance Tester Model 3731 measures ground rod and small grid resistance through any season, without the use of auxiliary ground rods.
Check Resistance on Single and Multiple Rods or Grids
Clamp-on Ground Resistance Testers are used in multi-grounded systems without disconnecting the ground under test. The Model 3731 simply clamps around the ground conductor or rod and measures the resistance to ground. By performing measurements on intact ground systems, the user also verifies the quality of the grounding connections and bonds. Resistance and continuity of grounding loops around pads and buildings may also be measured.
The Model 3731 also provides alarm and memory functions.

Ground resistance meter 3-electrode measurement on the 3151 gives greater precision !
Ground resistance measurement involves factors that are not encountered during ordinary resistance measurement, such as polarization of the earth, the influence of grounding current due to leak current and grounding voltage, and the influence of auxiliary grounding resistance. The 3151 is able to make more accurate measurements more safely under difficult conditions because it uses the alternating current potentiometer method to provide measurement accuracy, and because it contains features such as an auxiliary grounding resistance check feature and measurement frequency switching.

With the HFM 436 Lambda, samples measuring 30 cm x 30 cm or 60 cm x 60 cm and of variable thicknesses ranging from a few millimeters to 10 (20) cm are tested between two heat flux sensors in fixed or adjustable temperature gradients. After a few minutes for the system to reach equilibrium, the built-in PC or external computer determines the thermal conductivity and thermal resistance of the sample.
Automatic plate movement and determination of the sample thickness simplify test preparation.
All test parameters as well as the calibration data are stored in the PC and documented.
Determination of thermal conductivity with the HFM 436 Lambda meets the industry standards ASTM C 518, ISO 8301, JIS A 1412, DIN EN 12939, DIN EN 13163 and DIN EN 12667.
