Instruction Manual
IMPORTANT:
For safety reasons and correct function of these switches it is strongly recommended to
carefully read this instruction manual before installation!
Application
The DP660 is a vibration type level switch that detects the minimum or maximum level in bins,
silos and hoppers. Typical applications are for granular and pellet products.
IMPORTANT:
The switches cannot be used for detecting sticky materials that tend to build a deposit on them.
The DP660 is not recommended for detecting fine powders.
General Notes:
Installation and maintenance must be performed by qualified technical personnel only.
The DP660 must be used only in the manner outlined in this instruction manual.
The vibrating level switches DP660 are sensitive sensors which need to be handled with
care. Never expose them to mechanical loads and temperatures higher than indicated in
the technical data or make any changes to them.

- Page 2 Function The signal from the electronic circuit of the DP660 excites the probe to vibrate at its resonance frequency of approximately 460Hz. When material covers the probe the vibration stops. This is sensed by the electronic circuitry which forces its output to switch.

- Page 5 Maintenance The vibrating type level switches DP660 require no maintenance. For applications with materials that are slightly sticky we recommend cleaning the vibrating rod after a certain period of time. If the switches are exposed to a corrosive atmosphere they must be inspected periodically to avoid corrosion, in order to ensure the continued protection of the switch.
