KOBOLD Instruments, Inc.
NLP  Hydrostatic Pressure Level Switch The KOBOLD NLP Hydrostatic Pressure Level Switch excels at level control in open tanks where suspended solids are present. Operation of the switch is based upon the change in hydrostatic pressure within the standpipe. When the media rises or falls to the desired level, the changing air pressure within the tube reacts on the internal diaphragm, actuating or deactuating the SPDT contact within the switch housing. The KOBOLD NLP has no moving parts, requires no external power, operates... (read more)
