Conductive Rod Level Sensors

TURCK 6/5/2018
 
TURCK liquid level probes may be used in conjunction with TURCK level control monitors, to provide a simple solution for liquid level applications. The resistance between the terminals is measured to determine the level of the medium in the tank.
 
TURCK also offers stainless steel probes and stainless steel holders with ceramic insulators. The probes are used to provide single-point level control, while the holders are sealed to withstand applications up to 2500 psi at 70° F (21°C).
 
WHY CHOOSE ROD LEVEL SENSORS AND CONTROLLERS?
 
 • Adjustable sensitivity
 • Single set-points
 • Multiple inputs
 • On/off delay
 • Programmable outputs

WHERE CAN I USE ROD LEVEL SENSORS AND CONTROLLERS?
 
• To control the filling and draining of a tank, or as high and low level alarms.
• To differentiate between a variety of liquids, as well as distinguishing between liquid and foam.
• To set an adjustable on and off-delay for use in turbulent liquid level applications.
• To control overflow monitoring.

Level Detection Application Examples
 
Control for Pump-in “Filling” a Tank
 
The MK91-12-R will start a pump or open a fill valve when the liquid drops below the MIN level probe and will remain on until the MAX level probe is reached. The relay then de-energizes and stays off until the MIN level is reached. The pump or valve does not cycle constantly, as would be the case if only one sensor were used.

Control for Pump-out “Draining” a Tank
 
The MK91-12-R will start a pump when the liquid reaches the MAX level probe and remain on until the MIN level probe is reached. The relay then de-energizes and stays off until the MAX level is reached. The pump or valve does not cycle constantly, as would be the case if only one sensor were used.
