Description
The level regulator type NR 1/2”,3/4”,M20,M24-EExi for tank insert is a solenoid switch, operating without contact with the function of monitoring and regulating liquid levels and temperatures.
The switching tube contains bistable protective gas contacts, fixed in position. For fixed contacts, the contact intervals and their function must be agiven.
The permanent magnet, built into the float, switches the contacts when the level changes. The switching difference (hysteresis) is 4mm. For temperature monitoring and regulation, thermal elements such as thermal contacts can be additionally incorporated.
The level regulator is maintenance-free for nondeposit media.
The device has to be installed by specialists only.
