Pomiar poziomu granicznego w zbiornikach: 10 najważniejszych zastosowań

Many applications in the production of liquid and viscous food require exact point level measurement. Examples are the precise detection of a defined fill level to prevent a tank from overflowing, to protect pumps or to control valves. This large variety in application locations also leads to numerous challenges that need to be solved before point levels can be accurately determined. We have put together the 10 most common requirements along with a suitable sensor solution for each one.

Use in tanks

Requirement:

Sensor is built into the tank from above.
Space between the tank cover and the medium.

Solution:

The space is bridged by a rod.
Highly flexible sensor: The length of the sensor tip can be adjusted to the requirements of the user to the nearest millimeter.

Suitable sensors:

NCS-L-11

Requirement:

Installation from the side.
An agitator is built into the tank.
Easy to clean.

Solution:

Low submersion depth into the medium because of the compact design of the probe tip.
The material prevents the formation of accumulations such as caustic deposits, making the unit very easy to clean.

Suitable sensors:

NCS Standard
NCS-L-1x/18

Requirement:

Restricted space for installation of the sensor due to other lines or attachments.

Solution:

Compact Plug & Play sensor.
Installed like a spark plug using a ratchet; this results in minimum clearance requirements to the next attachment
No special settings/medium calibration needed for installation.

Suitable sensors:

NCS-M

Requirement:

Sensors that are installed on the sides or in the floor are more likely to develop deposits on the sensor tip in viscous or adhesive media. The sensor must nevertheless switch properly.

Solution:

The additional PEEK insulation shifts the sensor tip further toward the middle of the tank, helping to prevent the formation of deposits on the tip.

Suitable sensors:

NCS-L-1x/50

Use in double-walled tanks

Requirement:

Installation of the sensor in a double-walled tank.

Solution:

The point level switches from Anderson-Negele can be readily built into doublewalled tanks using weld-in sleeves; please ask us about this technology.

Suitable sensors:

NCS-L-1x/50…-L60
NCS-1x/…-L60
NCS-L-11/…-L60

Use in piping

Requirement:

In downpipes below a tank, liquid from the tank may still flow over the
sensor tip after draining has finished.
A rapid empty indication should nevertheless be ensured.

Solution:

The sensor tip is shifted further toward the middle of the pipe to a position where it cannot be reached by liquid flowing out of the tank after draining.

Suitable sensors:

NCS-L-1x/18
NCS-L-1x/50

Requirement:

Installation into pipes with a small cross section:
Conventional sensors cannot be used in constricted spaces :

Solution:

Sensors of type NCS-0x can be used in pipe diameters as small as DN15

Suitable sensors:

NCS-0x

Information

All of the special designs mentioned above have the same advantages as the standard sensors of the NCS series, namely:

Available in high temperature versions for use at process temperatures up to 140 °C.
Rapid response times down to 100 ms for accurate control processes, such as in filling applications.
Adjustment of the sensor to the medium requires nothing more than a screwdriver. Neither programming tools nor software skills are necessary.
The switching state of the sensor can optionally be viewed from the outside.

As a specialist for point level indicators, Anderson-Negele offers a suitable solution for almost any measuring problem with its capacitive NCS series. Please let us know what we can do for you.
