Sand Level Control and Signaling Device SPK-1

Purpose

Sand level control and signaling device SPK-1 is designed for continuous automatic control of filling with sand, silt, etc. of settling tank containers and other reservoirs.

Application Area

Food, chemical, enrichment and other industries.

Principle of Operation

The operating principle of signaling device SPK-1 is based on measuring the ratio of signals from conductometric sensors, one of which is installed at the level of permissible sand accumulation, and the second - above this level.

Product Composition

Signaling device SPK-1 consists of two conductometric sensors and a converter for signaling and controlling technological equipment.

Advantages

Ability to control sand level in tanks regardless of wastewater contamination with alkalis, acids, etc.
High reliability
No moving parts
