Detail Capacitance E+ H Silometer FMC420
Mechanical: Silometer FMC instruments in Minipac housing are ideal for control panel mounting. As compact units they can be mounted side by side on a standard symmetrical 35mm DIN rail. Removable terminal blocks make them easy to wire up. The instruments can be replaced without resoldering the wiring. A protective housing IP 55 with transparent cover is available for mounting in the open. The calibration elements are located under the flip-up front panel and are easily accessible whilst being protected from unauthorized use. The inside of the front panel shows diagrams to facilitate calibration. Electrical: Build-up on a capacitance probe: This problem is usually solved by choosing the correct probe and the electronic insert EC 72 Z. A hydrostatic probe also operates where build-up occurs providing the material does not crystallise to form a hard crust. Easy calibration: Zero calibration is carried out when the container is empty and the measuring span ( amplification) is adjusted when the container is full. These instruments have the advantage that amplification is independent of the zero point. The flashing row of LEDs on the front panel of the Silometer FMC 423 allows 0% and 100% to be set accurately without the use of auxiliary instruments. Field of application The Silometer is used for continuous level measurement in tanks containing liquids. The Silometer FMC 423 is also used as a level limit indicator or as a two point controller with adjustable switching differential. The wide range of capacitance and hydrostatic probes ( pressure sensors) allows measurement: in aggressive media at high pressures or vacuum at high or low temperatures in high or low viscous liquids in media where build-up is expected, etc.
