OUR COMPANY IS THE MANUFACTURER OF A COMPREHENSIVE MONITORING AND DIAGNOSTICS SYSTEM КD2210 FOR EVALUATION OF THE TECHNICAL CONDITION OF PUMP AND COMPRESSOR EQUIPMENT

Vibration transducer КD618

KD618-29-08-2017Vibration transducer КD618, manufactured by LLC "Komdiagnostika", provides information about the current technical condition of the pump equipment based on vibration levels and temperature at the installation site.

Vibration transducer КD618 is piezoelectric accelerometer of inertia type, which uses direct piezoelectric effect with integrated temperature sensor. Sensitive element electric charge is proportional to acceleration affecting the vibration transducer.

Application: measurement of absolute vibration and temperature of the controlled rotating and reciprocating units during their operation.

Vibration transducer КD618 is an explosion proof device and has the marking «0ExiaIICT4 Х» according to GOST 30852.0-2002, GOST 30852.10-2002.

Technical specification of КD618 is proved by TR CU certificate No. ТС RU C-RU. ГБ08.В.02222 (validity period 27.12.2016 - 26.12.2021).
