Frequency transmitters - Import export

CSN® Dummy Load Resistors used as dummy loads for testing high frequency radio transmitter systems. Schniewindt had already supplied dummy load resistors with rated max. cont. power up to 1500 kW. CSN® Dummy Load Resistors are designed and manufactured individually to customer requirements and specific application.

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.

PiTract is a wireless data transmission device operating on the principle of a radio extension, i.e. transmits data packets captured via the RS-485 serial interface to the radio channel and retransmits them to the serial interface on the reverse side. PiTract operates in the 2.4 GHz unlicensed frequency band (ISM), with a maximum power not exceeding 100 mW, so there is no need to obtain an additional permit to operate in this frequency range. Radio channel parameters such as transmitter power, frequency channel number, modulation settings, as well as serial interface settings can be flexibly configured for a specific task of the Customer. PiTract is ideal for working with remote or moving objects. The applied latest LoRa transmission technology provides excellent sensitivity and noise immunity, which allows PiTract to be used in industrial facilities that are in a difficult interference environment.
