High-voltage resistors - Import export

Since the invention of the “Schniewindt grid” in 1902, we produce high voltage resistors and are thus among the pioneers in the electrical industry. Due to continuous development of our products and new developments according to the respective needs of the market, we are now one of the leading manufacturers of electric heating equipment, resistance equipment and sensors for current and voltage measurement

Our High-voltage resistors resp. High ohmic resistors are a available as flat and tubular resistors, in various series and as adjustable high-voltage potentiometers.

Precision resistors are used wherever the highest standards of temperature stability, error tolerance and durability are required. Models 1164 and 1166 are available for higher loads up to 1 W. The resistors are supplied with two connections on the front end (suitable for mounting on circuit boards). The precision resistors comprise low-capacitance, low-inductance wire coils made of MANGANIN®, which are encapsulated in small plastic cylinder housings. Prior to trimming, the resistance bodies are exposed to a meticulous artificial aging procedure. This special process and trimming to approximately half of the nominal tolerance guarantee long-term stability of < 0.02% over the course of years. FEATURES: — TC ≤ 10 ppm/K —Class ± 0.02 % or ± 0.05 % —Production range from 5 Ω ... 100 kΩ —Resistance material MANGANIN® —Custom resistance values available on request —Minimum order per resistance value 10 pcs

Today resistance thermometers are one of the important precision and operating measurement instruments of technical temperature measurement. Fast and easy testing of display, control and recording devices in measurement and process engineering is essential. Fixed temperature values can easily be simulated according to the characteristic curves of Pt100, Pt500 and Pt1000 using the precision resistors calibrated in °C (the inscription also includes the resistance value in Ω). The small dimensions of the resistors allow the installation in measuring instruments or measuring circuits for comparison or control measurements. Features: — TK ≤ 10 ppm/K — More than 60 fixed temperature values from -200 °C ... +800 °C ex stock — Calibration in acc. with DIN EN 60751 n - 0.02 % tolerance for the models 1144-Pt 100, 1144-Pt 500 and 1144-Pt 1000 — ± 0.05 % tolerance for model 1146-Pt100 — Resistance material MANGANIN®

The Metzner EM 300 platform offers further convenience in high-voltage cable processing through a quick change of process tools and faster cycle times. Depending on the requirements, the HV cable processing machine can thus be equipped with different tools for cable processing. This means that the EM 300 can be used for several processing steps and is prepared for a wide range of processes. In addition, with the EM 300 we protect your investment by offering improved expandability that enables “plug-and-play” integration of future new applications.

Metzner has a clear understanding of the future and transforms existing processes into fully automated system solutions. Workstations that were previously operated separately are now combined into fully automatic production lines. The starting point of an automatic processing line is the cable that is wound on a reel. The end result is a finished cable with a completely assembled plug system

Multiple EM 600 stations in combination with a cost-effective transfer system provide the additional benefits of the EM 700 series: higher degree of automation, no limit to the number of stations, modular and scalable, single- or double-sided processing
