Resistors - Import export

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.

A drive motor can also act as a generator. If the drive system is built so as to allow reverse power to flow then this power can be fed into a resistor, thus taking energy out of the system and causing whatever is driving the motor to slow down. Following to this the braking resistor converts the stop energy into heat. Electrical drive systems are being used more and more on ships, oil rigs, crane barges and offshore vessels of all types. An important benefit from using an electric drive is that reliable systems of regenerative and dynamic braking resistors are available to complement or replace traditional mechanical braking systems. The advantages of electric braking include control, reliability, mechanical simplicity, weight saving and in some cases the opportunity to make use of the regenerated braking energy. The Braking Resistor Units from Klöpper Therm are designed according to specific applications.

Temperature is one of the most measured physical parameters. Despite this, precise temperature measurement is one of the most difficult tasks in motor technology. To meet the constantly increasing requirements for improved motor performance, higher efficiency and reduced emissions, it is necessary to use reliable and precise sensors in modern motor control systems. The increased requirements over the last few years regarding measurement accuracy and reliability of temperature measurements has meant that many equipment operators must reconsider the suitability and performance capacity of their temperature measurement equipment. Resistant thermometers can be used between -200 °C and +850 °C. An important common property is that their output parameters are available in the form of electric signals that can be relatively easily transferred to measurement and control instruments for processing, storage and display.
