Sensing fibers

Steelskin plastic sensing fibers feature Dura-Bend multi-core construction that allows them to carry light through tight radius bends without signal loss or fiber damage. The fibers are protected by a braided 304 grade stainless steel over-jacket. With a minimum bend radius of 10 mm and an outside diameter of 2.9 mm, they’re designed for low-profile applications embedded in machinery. The fibers are terminated with plastic ferrules for interfacing to the company’s FP style amplifiers and can be used with most fiber optic photoelectric sensors.

Insulation tester

The 61-792 Megger 5kV insulation resistance (IR) tester features hand crank and battery operation. The IR tester has a measuring range of 100K to 20Gohm, with four test voltages: 500V, 1,000V, 2,500V, and 5,000V for measuring high-power motors and electrical systems. An automatic discharge circuit eliminates the capacitive charge created by the tester immediately after test. The tester features a large analog display and a locking or non-locking test button. The button enables hands-free testing, while the non-locking button is recommended to prevent accidental or unauthorized use.

PQ analyzer

The PNA-600 portable PQ analyzer is NEMA4/IP65 rated, so it’s sealed against moisture and dust. The laptop computer-sized analyzer is powered by a 950 MHz Celeron or PIII processor and has 256 MB of RAM on a single-board computer. The system has four voltage inputs 600V rms and four current inputs via current transducer coils. It analyzes to the 50th harmonic, and has an FTT analyzer, oscilloscope, a flicker meter, and power quality monitor. The instrument’s flat TFT display can rest on a desktop, be held in an operator’s hand, or be mounted to any surface using a threaded mount.
