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

In connection with very precise digital voltmeters the model 1282 resistors are used as measuring resistors for accurate registration of direct and alternating currents up to 200 A. The compact construction supports universal application. The exceptional low temperature coefficient extends the scope of application a second time. A typical application is the wide range of quality and reliability testing. Regular measurements give a reliable information of the quality level of parts, instruments and systems. Technologies already approved with our precision and calibration resistors - which especially guarantee a secure conduction of the dissipation heat - have been transferred to the precision high capacity resistors. Features: — Temperature coefficient ≤ 10 ppm/K — Nominal load 20 W — Ranges 1 mΩ ... 100 mΩ — Four-terminal measurement principle — Accuracy 0.02 % — For technical frequency 50 Hz

In its function as temperature simulator the decade offers the choice of sensors like Pt100, Pt200, Pt500, Pt1000, Ni 100 and Ni 1000 in the range from -200 °C up to +850 °C. The temperature is entered via keyboard or data interface. The corresponding resistance appears at the output socket in two, three or four wire method. The resistance decade allows a direct choice of resistances between 1 Ω and 1.2 MΩ. Depending on the ohm value the resolution can be chosen up to 0.00001 Ω. The selected resistance can be picked up via two or four wire method. The LCD display informs about chosen resistance or temperature, sensor type and control status. Features: — Resistance range from 1.00000 Ω to 1.200000 MΩ — Accuracy 0.005 % — Temperature coefficient < 1 ppm/K — Simulation of RTD (Pt, Ni) temperature sensors — Simulation accuracy 0.02 °C — 2, 3, 4 wire connection — USB/RS232 (IEEE488/Ethernet optionally)

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®
