The 11961Z is a highly resistant probe for applications with aggressive medium thanks to corrosion-resistant materials for rod and insulation. It can be used in steam boilers thanks to ceramic insulation resistant to steam and hot water.

For conductive point level detection in process or storage tanks, for conductivity as of 0.02mS/cm. As overfill prevention with line monitoring even in Ex-area Zone 0, or pump protection in pipes and two-point control.
