Meters - Import export

Wind velocity indicators are used for detecting and in connection with the appropriate indicator, monitoring a maximum wind velocity. They are used mainly in safety and monitoring systems of cranes and excavators. Two models are available. One with pendulum orientation, especially suited for the attachment on jibs of mobile cranes, and a common one, pedestal mounted or mounted on a vertical post. The output signal, being proportional to the wind velocity is taken either from a built-in tachometer generator in form of a voltage or from an optoelectronic impulse transmitter with frequency-current converter in form of a current signal in two-wire technique. For applications in the temperature range down to minus 50 °C there is optionally available for both models a mounting arrangement for a temperature controlled heating device. Cross arms feed-through sleeve and crown are splash-proof, degree of protection IP 65.

Rope Length Transmitter with high precision analog or digital encoders The determination of measuring lengths in the range of one up to several meters is preferably carried out by using well priced and easy-tomount transducers on the basis of the draw wire measuring principle. In connection with measuring problems of industrial applications e.g. on - cranes, drilling machines and excavators - pressing, punching and injection moulding machines - weirs and lock gates - multilevel shelving rack systems and theatre stages - wood- and stone-working machines and also in - instrument engineering, high-tech medical devices etc. Rope length measuring systems series SL 3000 have proven for years to be very reliable, capable of measuring lengths up to 40 m with high accuracy and reliability even in extremely dusty and moist atmospheres.
