Capacitive proximity sensors with PBT housing | for liquid detection in pipes | in tanks
-
Non-contact capacitive sensors for liquid detection – automation components designed to detect the presence or level of liquids without direct contact with the material.
They respond to changes in capacitance (electric field), allowing them to detect water, oil, fuel, chemical solutions, or other liquids even through non-metallic walls – for example, through a plastic or glass container or pipe.With a PBT plastic housing, these sensors are resistant to chemicals, moisture, dust, and temperature variations, while the IP67 protection class makes them suitable for use even in harsh industrial or household conditions.
An ideal choice for monitoring water, oil, or other liquid levels both in household and industrial applications.Main features:
Detects liquids through non-metallic containers (glass, plastic, etc.)
Operates without direct contact with the liquid
Capacitive operating principle – responds to changes in the electric field
Suitable for water, oil, chemicals, fuels, and other materials
PBT housing – resistant to chemicals and moisture
Easy to integrate into equipment or tank walls
IP67 protection class – water and dust resistant
Usage and applications:
For household users: suitable for monitoring water levels in aquariums, tanks, boilers, or domestic water systems. Since it operates without direct contact, it avoids issues like scaling, salt buildup, or corrosion.
For engineers / automation specialists: used in production processes, dosing, cooling, or filling systems. Suitable for food, pharmaceutical, plastic, or chemical industries where direct sensor contact with the material must be avoided.
For electricians / technicians: easy to install with clearly marked terminals. Standard power range and output types allow connection to controllers, PLCs, or signal indicators.
Pros:
Non-contact operation
Detects through walls – no direct contact required
Resistant to moisture, chemicals, and temperature variations
Easy surface mounting
Suitable for water, oil, fuel, and solutions
Reliable operation even in dusty or vibrating environments
Long service life and minimal maintenance
Cons:
Not suitable for metallic tanks (capacitive signal blocked)
Detection distance depends on wall thickness and liquid type
Requires proper calibration for the specific material used
Non-contact capacitive sensors with PBT housing for liquid detection – a universal, safe, and hygienic technology ensuring precise liquid detection control without direct contact.
Suitable for both household and professional industrial automation applications where reliability and environmental resistance are essential.
