Level limit switch Capcont M
The level limit switch Capcont M with integrated evaluation electronic are compact fill level limit switches for supervision of fill levels in liquids and solid materials in containers or pipelins at process temperatures from -30°C to +125°C and process pressures from -1 up to 10 bar.
The sensor is suitable for limit value detection or also as dry run protection in liquids and viscous substances but also in powdery and fine-grained materials, like e.g. grain, flour, powdered milk, mixing food, cement, chalk or gypsum. It can be used in electrically conductive as well as non-conductive materials.
Application
- Fill level resp. limit value detection in container
- Dry run protection for pumps
- Useable in liquids, viscous substances, granular materials or powders
- Useable for electrically conductive and non-conductive substances
Advantages
- Easy commissioning
- Suitable for a wide process temperature range from -30°C to +125 °C
- Useable at process pressures from -1 to 10 bar
- Fully isolated electrode rod with isolation 1mm in PTFE
- Integrated evaluation electronic with PNP switching output – invertable
Function
The fill level limit switch Capcont M is a capacitive operating sensor with limit value detection.
Electroden rod, filling material and container wall realizes an electrical capacitor. A fill material changing causes a capacity change that is evaluated by the electronic and is converted into a corresponding switching reaction. At transgression or underrun of the limit value a switching signal at the PNP switching output is created. This allows a control of relays, contractors, magnetic valves, light signaling units, horn as well as SPS inputs. A plugable yellow LED indicates an active PNP switching output.
A possibility for change over the minimum / maximum safety is integrated.
