NSV - Vibrating Level Switches for Bulk Media

Brand: KOBOLD Instruments, Inc

The KOBOLD NSV level switch excels in low density bulk media and is easy to maintain. It detects level via vibration technology.

The vibrations are induced into a stainless steel fork by a piezoelectric crystal.

When the media contacts the fork and dampens the vibration, it is detected and then transformed into a potential-free limit contact.

In addition to the standard model NSV-8200, the model NSV-8201 offers vertical installation via an extended neck pipe up to 118".

The sensitivity can be set for maximum or minimum via a selector switch. The status of the switch is indicated by an LED light.
