Level controller with relay output CV6

for storage tanksfor solids and liquidsfor hopper

The CV 6 series vibrating rod level controls are divided into four models: CV 600 in compact design with reduced immersion length CV 630 always in compact design and with immersion part lengths from 300mm up to 1m CV 650 still in compact design but with rope probes up to 4m Low cost, small size, no calibration, fast installation, ideal for all types of granular solids contained in small hoppers or for interface measurements. CV 600 is a tool control system that determines the minimum and maximum level in tanks, silos and hoppers. For its small size CV 600 is ideal for small hoppers that process any type of granulate such as plastic grains and food. CV 600 is ideal for materials with a volumetric weight greater than or equal to 50g/litre. The signal from the CV 600’s electronic circuit excites the probe’s steel rod, which vibrates at its resonance frequency of about 460Hz. When the material covers the probe, the vibration is dampened and the electronic circuit drives the output relay. When the material uncovers the probe the vibration starts again and the relay switches its state. Only the final part of the probe is sensitive, but not the base, so any build-up of material does not affect the function of the probe. The CV 660 has the same features as the CV 600 but is powered at 24 Vac/dc and has different dimensions. The CV 600 offers several advantages over other level control techniques: has no moving parts maintenance-free is insensitive to changes in temperature, humidity or pressure is insensitive to variations in the material to be controlled is insensitive to dust or material movement – must not be programmed is versatile vibration has a self-cleaning effect
