Field of application
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.
Process connection: Thread
Measuring range: 100 to 2,000mm (5.9 to 78.7")
Temperature: -200 to +250°C (-328 to 482°F)
Pressure: -1 to +160bar (-15 to +2,320psi)
Components: Transmitter FTW325
International explosion protection certificates, overfill prevention WHG
Benefits
Safe and reliable measurement even in aggressive medium thanks to corrosion-resistant materials for rod and insulation
Can be used in steam boilers thanks to ceramic insulation resistant to steam and hot water
Can be deployed particularly with high pressure or vacuum
Probe can be shortened as required
