Vertical mounting LRNV-P

Model for vertical mounting with Nylon or Popypropylene (PP), Ø 21x30 mm float, 1 NO contact reversible to NC, with extension under request, thread process connection and DIN 43650 output.

These devices are used to control the level in tanks, containers, bypass pipes, ... of liquids like waters, oils, chemical products, ... with non-ferric particles in suspension are used. This model is specially indicated to be control the maximum, minimum or an alarm level in small tanks.

The indicator LRNV-P are the float switches VS with an extension. The magnetic float switches have a guide-way body where a float moves. Inside the body there are REED contacts that change its position due to the magnetic field of the magnet placed inside the float when arrives at the contact point. When the liquid level falls, the float moves back and the signal turns into the initial position.

To reverse the NO contact to NC contact, take the float out and change the position 180º.

The standard form is mounting the device with the thread connection in the top of the tank or container or through a tube. The thread is G 3/4 " male, and can be fixed introducing it into a threaded socket or using 1 nut.

Depending on the application, the indicator can be mounted from the bottom of the tank or container (facing down).

For a correct use of the level switch, the float must not touch the walls of the tank and it is necessary to ensure the free movement of the float.
