This polypropylene version is based on ifm’s proven LDL200 inductive conductivity sensor. Its material properties make it the ideal choice for applications in which metallic sensors tend to corrode. Perfect for aggressive, acidic or alkaline media, such as cleaning agents or when in direct contact with salty ambient air. The measuring channel with an internal diameter of eight millimetres ensures optimum flow of the medium while minimising the risk of blockages.
It can be used in almost any stage of the water treatment process.
The conductivity of a medium is measured from 100 to 2,000,000 µS/cm and output as a temperature-compensated value. The wide measuring range means it can be used in almost any water treatment application.
Standardised M12 connector instead of error-prone cable gland.
The standardised M12 connector with an impressive ingress protection rating of IP 68 and IP 69K, it withstands severe operating conditions. Moulded plugs allow for quick connection and eliminate wiring errors as there is no terminal chamber.
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.
Fish farming – keeping the ecosystem in balance
In fish farming, the sensitive ecosystems must be precisely controlled 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.
IO-Link digital communication to the sensor
- Precise transmission of process values
- Reduced wiring with decentralised IO-Link masters
- Seamless digital information and values
- Sensor data can be used via IIoT for MES & ERP
- Best possible resolution across the entire measuring range
- With IO-Link, the resolution of the conductance is always scaled to suit the used measuring range, so that the highest possible accuracy is always guaranteed.
IO-Link converter
The EIO104 converter quickly and easily converts IO-Link process values into two 4…20 mA signals. This means that IO-Link sensors can be easily connected to existing controllers featuring only analogue input cards.
Analogue integration
With analogue integration, the process value is output as a 4…20 mA signal.
The LDL400 is supplied with 1 x analogue output
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 via IO-Link, making it easier to replace the device – only the device needs to be replaced.
