The measuring range up to 450 k? enables a differentiation between foam and liquid. It also increases the universal application for resistance measurements.

Due to its low-frequency, electrically isolated measuring circuit, the device has a high immunity to interference against system coupling, which enables cable lengths of up to 1500 m and suppresses the effects of electrolysis in the liquid

• The two outputs for minimum and maximum control can also be used for the advance warning and tripping of limit values
• 3 electrode connections for 1-step and 2-step level control
• All standard products can be used as electrodes
• High immunity to interference of the measuring circuit isolated from the system
• Programmable for open-circuit principle (with bridge X2 COM) or closed-circuit principle (without jumper)
• Separately adjustable delay times for t_v min and t_v max, 0.2 to 2 s.
