Preamplifiers DAKEL are produced using hybrid technology - surface mounting and thin film components on on ceramic substrate, dimesions 7 by 7 milimetres.
Preamplifiers are intended for signal amplifying and for adapting of high sensor impedance to low device impedance. If a coaxial cable is longer than 2 m impedance converter & preamplifier must be used.
External amplifier is powered from input of evaluating device via coaxial cable, if DAKEL-XEDO or DAKEL-IPL is used.
