Vibration speed sensor current type (4-20mA output) LZDSL1-930

1） Overview:
The vibration speed sensor current type (4-20mA output) LZDSL1-930 is a current type speed sensor independently developed by our company. All its indicators meet the requirements proposed in ISO2954-1975 and GB13824-1992. This series of speed sensors adopts the principle of piezoelectric effect, processed by internal amplification circuit, voltage current conversion output, and two-wire circulating current working mode. Adopting a 4-20mA effective value output method, it has low noise and strong anti-interference ability, suitable for long-distance measurement, and is suitable for vibration acquisition in industrial systems such as PLC and DCS.
