The explosion-proof integrated vibration transmitter DK300 guarantees reliable and permanent monitoring of the total vibration, and a built-in precision integrated circuit to provide speed output. Compared with the magnetoelectric speed sensor, it can work in the frequency range of 2 - 1680 Hz and is indicated by an accurate linearized 4-20mA analog output. The vibration transmitter DK300 has a service life of up to 7 years, has wiring fault tolerance protection, excellent stability and reliability and strong anti-interference ability, which can meet the requirements of harsh industrial environments.
