Product Details

Description

The NIVOCONT R series of vibrating rod level switches are robust instruments designed for low and high level indication of granules and powders with a minimum of 0.05 kg/dm³ density. Mounted on tanks, silos or hopper bins it can control filling / emptying, or give fail-safe alarm signals. The highly polished version is recommended to use for abrasive mediums.

The operation principle is based on that the electronic circuit excites a vibration in the rod probe. When the medium reaches and covers the rod, its vibration stops, when the medium leaves the rod it returns to vibrate freely. The electronics senses the change of vibration and gives output signal after a selected delay.

NIVOCONT R Main Features

Extension up to 20 m
Adjustable sensitivity
Max. medium temperature: 160 °C
Universal supply voltage
Dust explosion protection
Fine polished probe
IP67 protection
5 years warranty
