Water-Rich Dairy Products
Models for milk and related liquid products with relatively high water content and a correspondingly strong dielectric response.
- Milk and dairy beverages
- Water-rich food liquids
- Tank or pipe point-level detection
OEM Point-Level Sensing Electronics
Capacitive Sensor Electronics
Application-tuned level detection for liquids and semi-liquids.
EIB Solutions supplies the electronic sensing platform for integration into an OEM’s probe, process fitting and enclosure. Dedicated variants can be configured for water-rich dairy products, fats and oils, and selected hydrocarbon or alcohol-based liquids.
Point-Level DetectionHigh, low or product-presence switching.
Application TunedCalibration matched to the target medium.
Electronics OnlyNo sensor body or mechanical process parts.
OEM SupplyFor integration into manufactured equipment.

Air
Process MediumDielectric change detected
Probe Electrode
The medium changes the capacitance around the electrode. The electronics evaluate that change and provide a control signal at the defined point level.
OEM OnlyNot a retail sensor assembly
Electronics ModuleSensing and signal processing
Multiple Media FamiliesLiquid and semi-liquid variants
Custom IntegrationThreshold, output and PCB options
Media-Specific Models
Different products need different sensing behaviour.
Capacitive response depends on the dielectric properties of the material, electrode geometry and installation. EIB configures each electronics variant for a defined product family rather than treating every liquid as identical.
FAT
Fats & Edible Oils
A separate sensing configuration for lower-dielectric products such as milk fat, butter, ghee and vegetable oils.
- Butter and milk-fat products
- Ghee
- Vegetable and edible oils
HC
Hydrocarbons & Alcohols
Application-specific versions for compatible fuels, solvents and alcohol-based liquids after medium and installation evaluation.
- Petrol and hydrocarbon liquids
- Ethanol and selected alcohols
- Compatible process liquids
VIS
Semi-Liquids & Viscous Media
Electronics can be tuned for selected semi-liquid or pasty products, subject to probe design, coating behaviour and validation in the real process.
- Viscous food products
- Semi-liquid process materials
- Application-tested calibration
Operating Principle
Detect the material—not electrical conductivity.
The electrode and surrounding vessel or reference structure form a capacitor. When product covers the sensing region, its dielectric properties change the measured capacitance.
Establish the Empty State
The electronics establish the baseline capacitance of the probe and installation without product at the sensing point.
Measure the Dielectric Change
Product entering the sensing zone changes capacitance according to the medium, probe geometry and mounting arrangement.
Evaluate the Threshold
Application-tuned signal processing distinguishes the required covered and uncovered states.
Signal the Machine Control
The configured output communicates product presence or the selected high/low point-level condition to the OEM control system.
Machine Applications
One sensing principle, several control tasks.
Point-level electronics can support automated filling, product transfer and equipment protection when the complete sensing assembly is properly engineered and validated.
High-Level Detection
Signal when material reaches a defined maximum level in a vessel.
Low-Level Detection
Identify a minimum level for refill logic or process sequencing.
Overflow Prevention
Provide an independent point signal for the OEM’s overfill-control strategy.
Dry-Run Protection
Confirm product presence before operating a pump or transfer stage.
Pipe Product Detection
Detect whether compatible process material is present at a defined location in a pipe.
Filling & Transfer Control
Supply a repeatable switching input for automated batch or transfer equipment.
Clear Integration Boundary
EIB provides the electronics. The OEM completes the sensor.
The finished assembly must be engineered around the actual process, medium and regulatory environment.
OEM Sensing Electronics
- Capacitive sensing and signal-processing PCB
- Application-specific sensitivity and threshold tuning
- Output and interface configuration by project
- PCB form-factor and connector adaptation
- Prototype support and production supply
- White-label options for suitable OEM programmes
Mechanical & Process Assembly
- Probe electrode and reference geometry
- Sensor body, enclosure and process connection
- Wetted materials, sealing and hygienic design
- Pressure, temperature and cleanability validation
- EMC, electrical safety and required approvals
- Hazardous-area compliance where applicable
Important: Detection of petrol, ethanol or other flammable media requires a complete assembly specifically engineered and certified for the installation. The electronics module alone does not constitute hazardous-area approval.

Application Review
Tell us what the sensor must detect.
Share the medium, expected temperature, vessel or pipe material, probe concept, mounting orientation, coating or foam conditions, required output and annual quantity. EIB Solutions can then recommend the appropriate electronics variant and validation plan.
