Conductivity sensor made of polypropylene
The LDL400 is the polypropylene version of the proven LDL2xx inductive conductivity sensor. Its material properties make it the ideal choice for applications in which metallic sensors tend to corrode: direct contact with salty ambient air or other aggressive, acidic or alkaline media is no problem for the LDL400. The sensor also meets the high requirements of the marine industry and is certified according to DNV EU RO Mutual Recognition Type Approval.
The conductivity sensor in detail
Product benefits
Polypropylene housing withstands aggressive environments
The housing made of polypropylene makes the sensor the ideal choice for applications in which metallic sensors tend to corrode. Direct contact with salty ambient air or other aggressive, acidic or alkaline media is no problem.
The wide measuring range means it can be used in almost any water treatment application
The sensor continuously measures the conductivity of a medium in the range from 100 to 2,000,000 million µS/cm and outputs this as a temperature-compensated digital or analogue value. Furthermore, the percentage concentration of NaCl in ultrapure water can be accessed acyclically.
Certified for the marine industry
Thanks to its material properties, the sensor is ideally suited for use in the marine industry and is certified according to DNV EU RO Mutual Recognition Type Approval. This makes the sensor the ideal choice for water treatment applications on ships.
Compact design without additional evaluation unit
The compact design combines evaluation unit and sensor element in one housing. This saves space in the control cabinet and significantly reduces wiring complexity. It also eliminates the need for an expensive data cable between the measuring element and the evaluation unit.
Applications
Water treatment - filtration and desalinisation
The sensor continuously measures the conductivity of the medium in the range from 100 to 2,000,000 µS/cm. This means that the LDL400 can be used universally in almost every conceivable water treatment application and as an indicator of water quality.
The sensor also meets the high requirements of the marine industry and is certified according to DNV EU RO Mutual Recognition Type Approval.
Fish farming - keeping the ecosystem in balance
In fish farming, the sensitive ecosystems must be precisely controlled in order to enable successful and sustainable breeding. If the system were to become unbalanced, this would result in the loss of the entire breeding stock and a standstill in breeding.
The salt concentration of the water, a relevant measured variable, can be reliably determined at any time with the LDL400 via the conductivity.
Vertical farming - checking the concentration of minerals
In order to optimise the growth of a plant, it is not only necessary to determine and adhere to the water requirements, but also to check the concentration of minerals in the water.
The LDL400 can be used to measure this concentration and check whether it corresponds to the requirements. This ensures an optimum supply for the plants.
System connection
Added value thanks to IO-Link
- Transparent processes
Constant monitoring of conductivity and temperature allows you to keep an eye on your process at all times. The salt concentration of NaCl in ultrapure water can also be output acyclically. - Easy set-up, even remotely
The conductivity sensor can be configured quickly and easily via IO-Link - either remotely or during the process. No additional transducer is required. - Logging and simulation of process values and events
In addition to displaying and logging the process values, various events can also be recorded and simulated via IO-Link. - Backup & restore
Planning a device replacement? The backup & restore function automatically backs up and restores parameter sets, making it easier to replace the device - only the device needs to be replaced.
