For the solution, only the sensor is required to transmit the vibration data to the DCS or PLC data terminal, and there is no need to provide the output contact of the vibration signal alarm relay and the on-site data display. It is recommended to select the anti-interference integrated vibration transmitter produced by Shanghai Ruishi Company (anti-interphone interference, anti-electromagnetic wave interference and anti-surge interference). 

(1) The sensor of circulating water wind turbine installed in cooling tower has the requirements of on-site waterproof and intrinsically safe explosion-proof: 

RS5484E integrated vibration speed transmitter 

A. Intrinsically safe explosion-proof type (), IP68 waterproof type, the special cable (-40℃ ~ 220℃) led out by the sensor is connected with the sensor shell as a whole, and protected by stainless steel armor. The mounting bolt at the bottom of the sensor is an integral structure with the probe shell, and is provided with a mounting lock nut. 

B. Intrinsically safe explosion-proof type (), IP68 waterproof type, the special cable (-40℃ ~ 220℃) led out by the sensor is connected with the sensor shell into a whole without stainless steel armor protection. The mounting bolt at the bottom of the sensor is an integral structure with the probe shell, and is provided with a mounting lock nut.
