PRINCIPLE
Level limit switch for multiple point detection in conductive liquids
FEATURES
Detect up to five level limits with one probe
Two-point control and additional maximum and minimum detection
Flexible instrumentation:
- with built-in electronic insert, either transistor or relay output for 2 or 3 rod probes
- for connection to a separate transmitter power supply unit
No calibration required; standard setting for the most common conductive liquids
No moving parts in the tank:
- long service life
- reliable operation with no wear or blockages
WHG approval
Four measuring ranges can be set 100 Ω, 1 kΩ, 10 kΩ, 100 kΩ
Cost-effective probe for conductive liquids
Electronic inserts for:
- NAMUR output
- Relais output
- Transistor output
APPLICATION
Liquipoint T sensors are used in conductive liquids (as of 10 μS/cm) for determining level limits.
Depending on the number of measuring points (up to 5 rods), measuring tasks such as overspill protection, dry running protection, two-point control of pumps or multiple point detection can be implemented for an existing process connection.
