High Alarm Level Switch can also be used as low level alarm


High alarm level switch can be mounted in the bottom of the tank or top.  

The contact can be normally open or normally closed.  If the oil level reaches the float or

falls to the float it will change the state of the internal reed contact and can then send an alarm

or lock a control relay out. 


Pictured below is one of the popular models ATB3 but we have many many options, NPT size and materials.
