The maintenance free level indicators of the DF-series are the best choice for all level control applications in bulk solids. It doesn't matter whether it is dusty, powdery, or granulated bulk material; these measurement devices guarantee high reliability and safe operation even in very hard and extreme applications. The level measurement of sludge and pastes is no problem as well.
You can get all of these quality products with ATEX approvals for all potentially explosive dust and gas atmospheres as well as for hybrid mixtures. They are even suitable for applications with process temperatures up to 1.000°C and process pressures up to 25 bars. Such a wide range of applications make these rotary paddle switches unique in the world market.
As a matter of course our point level sensors are almost unlimited configurable and can be optimal adjusted to any difficult application.
