Primary element type MRK110-S / MRK110-SIL / MRK110-Ex-SIL

Application and function

• Continuous liquid level control in connection with an IGEMA
  magnetic level gauge and a standard controller.
• Remote liquid level indication in connection with an IGEMA
  magnetic level gauge and an indicating instrument (LED).
• Switching of freely selectable limit values in connection with
  a limit value switch.
• Combination from the cases of application 1 - 3.

The primary element is used as liquid level measuring device for IGEMA magnetic level gauges.
A float with integrated magnetic system is used in all IGEMA magnetic level gauges.  This float transfers the liquid level without direct contact to the primary element fixed on the outside
of the standpipe. The magnetic system actuates in the sensor pipe a resistance measurement
chain that corresponds to a 3-wire potentiometer circuit.

The produced measuring voltage is proportionally to the liquid level, and it is quasi-continuously
due to the sensitive resolution of the measurement chain.
 

Technical advantages:

The simple working operating principle allows an enormous range of application.

• Constantregistration of the liquid level independent of physical-chemical change of the medium state like frothing, conductivity, dielectric, pressure, temperature, condensate precipitation.
• Signaltransmission over long distances.
• Simple assembly and commissioning, singular adjustment, no re-calibration required
