Magnetic Immersion Probe for Limit Value Detection
LML-S
- Sensor for limit value detection in liquids
- Media contacting parts of stainless steel
- Mounting without removing the float (G5 and G6)
Function
- The device is a sensor for limit value detection in liquids.
- A ring magnet integrated in the float activates the contacts inside the probe tube via its magnetic field. If the probe strays outside the range of the mechanical contact, it reverts to the output status.
- The skipping of switching points caused by abrupt level changes can be avoided using snap-on set collars on the probe tube. The same set collars are also used for latching contact operation.
