System for level control STS 801

The STS 801 level control system serves for visualization and automatic or manual fluid level control. The main module in it is the STS401 process indicator. It allows automatic maintenance of setpoint level and hysteresis / signal from output OUT1 / and signaling when critical level / signal output OUT2 / is reached. The selection of the mode and the manual control is done by a switch and buttons on the panel. An indication of pump operation is provided. In manual mode, level indication and critical level alarm remain active. Output connections are potential-free. The system requires a level sensor with analogue output.

Technical parameters and connection schemes

Suitable for this purpose are:

UD64A01 / I / -1, UD64A01 / I / -2, UD64A01 / I / -4 – Output 0-10V;
UD64AI01 / I / -1, UD64AI01 / I / -2, UD64AI01 / I / -4 – Output 0-20mA;
UD73A01-10 – output 0-10V;
UD73AI01-10 – output 0-20mA;
UD74A01-10 – output 0-10V;
UD74AI01-10 – output 0-20mA;
UDT30AI1CL – output 0-10V, 0-20mA.

With a great distance between the system and the sensor, it is recommended to use a current circuit / sensor with current output. The STS-401 benchmark setup description is further provided.
