  • Explosion-proof grade: ExibIICT6
  • Protection level: IP67
Product Structure

The capacitive liquid level sensor consists of two main components: the sensor probe and transmitter. The structure varies based on application requirements.

A: Sensor probe that extends into the container or measuring tube

B & C: Gas phase and liquid phase connection flanges for equipment interface

D: Measuring cylinder that forms capacitance with the sensor electrode

E: Drain flange for periodic cleaning to maintain measurement accuracy

F: Transmitter that converts capacitance changes to 4-20mADC standard signal

Important: The sealing section between transmitter and measuring tube contains critical seals. Do not disassemble without manufacturer approval to prevent leaks or accidents.
Display Interface

Wiring Configuration

The KSLV606 display model supports two wiring methods:

RS485 Connection:

4-20mA Connection:

Isolated 4-20mA output wiring diagram Non-isolated 4-20mA 2-wire output wiring diagram

Installation Note: Always open the gas phase valve first, followed by the liquid phase valve to prevent measurement errors from liquid level fluctuations. Ensure cable connections are secure and corrosion-resistant. Regular maintenance includes periodic draining (1-2 times weekly for dirty media, monthly for cleaner media).

Common transmitter wiring methods:

Direct transmitter to digital display meter wiring diagram Transmitter to DCS control system wiring diagram Transmitter powered by safety barrier wiring diagram
Installation Guide

Standard Installation:

Gas phase and liquid phase installation diagram for level sensor

Connect the gas-liquid phase flanges to equipment flanges with gaskets and bolts. Ensure outlet pipes are clean and sealing surfaces intact before installation.

Note: Add valves between instrument and equipment flanges for easier maintenance.

Boiler-Specific Installation:

Special heat-dissipating structure protects transmitter from high temperatures. Ensure correct orientation with transmitter positioned below.

Calibration Procedure
External liquid level measurement control instrument calibration setup
  1. Prepare transparent pipe with scale, precision ammeter, rubber stoppers, and test medium
  2. Connect pipe to liquid phase port, block drain, keep gas phase open, and connect ammeter
  3. Add medium at 0%, 25%, 50%, 75%, and 100% levels, comparing ammeter readings to expected 4mA, 8mA, 12mA, 16mA, and 20mA outputs
Trouble Guide

Display shows zero: Check 24V power supply, transmitter for shorts or quality issues

Current below 4mA: Verify liquid level position, transmitter adjustment, or potential defects

Current exceeds 25mA: Check for transmitter circuit shorts or excessive current adjustment

Display fluctuations: Examine actual liquid level stability, connection quality, or transmitter issues

No display change: Test transmitter functionality and check for pipe blockages or connection breaks

Slow response: Clean sensor from impurities or check for partial gas phase blockage

Measurement Tip: Always test 24V power supply by connecting voltmeter to power line terminals.

Important Precautions
  1. Verify product documentation before installation
  2. Ensure interface compatibility with equipment
  3. Follow wiring instructions precisely
  4. Handle with care - avoid disassembly or impact
  5. Stop use and investigate any abnormalities
  6. Store in original packaging in cool, dry conditions
  7. Protect sensor from damage during handling
  8. Implement lightning protection measures
  9. Ground transmitter casing (resistance <4Ω)
  10. Use certified safety barriers for 485 communication
  11. Follow safety barrier installation requirements
  12. Use appropriate power transformers in hazardous areas
