Three axis vibration speed sensor current type (4-20mA output) LZDSL3-970

1） Overview:
Three axis vibration speed sensor current type (4-20mA output) LZDSL3-970 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, which is processed by an internal amplification circuit and converted into voltage and current output. Each channel operates in a two-wire circulating current mode, and the power line is shared. 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.
