Level switch, conductive (CFP)
• Level for conductive fluids
• PN2
• From 100 mm to 1000 height
• EPDM seals
• 30 VDC signal 1 or 2 relays///
• 2 points of regulation 1 relay 8 /250 VAC
General
• These probes are used for level detection or 2-point control in electrically conductive fluids.
Uses
• Level sensor with 2 probes as a minimum or maximum level indicator. – Level sensor with 3 probes as a 2-point controller.
Function
• These probes function as sensors using the conductivity principle; e.g. the electrical conductivity of the fluid to be monitored is used to determine the limit/fill.
Employment limits
• Conductive sensors are not suitable for fluids containing oil or grease or in which electrically insulating deposits can form. – They are not suitable for electrically conductive liquids. – They are not suitable for liquids containing large particles of solid substances. – They are not suitable for liquids that can attack stainless steel (1.4571).
