Scheme 1: only the sensor is required to transmit the shaft sinking displacement data to the DCS or PLC data terminal, and there is no need to provide the output contact of the shaft sinking displacement signal alarm relay and the field data display. It is recommended to choose the two-wire integrated displacement transmitter solution produced by Shanghai Ruishi Company.

1. The subsidence displacement of the shaft ranges from-1 mm to+1 mm or 0.5 mm to+2.5 mm.

Choose Shanghai Ruishi eddy current 8mm probe+extension cable+RS991 Eddy Current Two-wire Displacement Transmitter;

 2. The settlement displacement of shaft ranges from-2mm to+2mm or 0.5mm to+4.0mm or 0.5mm to+4.5mm.

 Shanghai Ruishi eddy current 11mm probe+extension cable+RS991 Eddy Current Two-wire Displacement Transmitter is selected; 

Scheme 2. The sensor is required to transmit the data of shaft sinking displacement to DCS or PLC data terminal, and the output contact of alarm relay of shaft sinking displacement data is required to provide field data display. It is recommended to choose the 4 channel and 2 channel protection instrument devices produced by Shanghai Ruishi Company.
