RK500-07LC
Liquid Cooling Turbidity Sensor

Establish a clean-loop baseline

Record normal turbidity after commissioning and coolant stabilization.

Monitor the trend

Look for sustained movement rather than reacting to every isolated reading.

Investigate sustained changes

Review operating conditions and check for possible particle or corrosion sources when the trend shows a sustained change.

90° optical measurement

Uses the 90° nephelometric method to measure turbidity online, with 0-10 NTU and 0-100 NTU range options and a specified response time of 1 second.

316L and sapphire

Overall 316L stainless steel construction with a sapphire measurement window. The specified applicable media include deionized water, PG25 and EG25.

Compact integrated design

No external modules are required. Simultaneous 4-20 mA and RS485 outputs connect to compatible monitoring equipment, with a 7-30 VDC supply and power consumption below 0.2 W.

Choose a stable flow location

Install on a bypass pipe for easier maintenance. Choose a location with steady flow and no obvious turbulence.

Vertical upward flow is preferred; a suitable horizontal pipe is also acceptable.

Avoid bubbles and deposits

Avoid high-point gas traps, low-point sediment zones, vertical downward flow and positions downstream of pressure-reducing sections.

Prevent bubble generation near the measurement window, as bubbles can affect readings.

Allow clearance in stainless steel pipes

Keep the probe at least 30 mm from the pipe wall to prevent backscattering distortion.

Prefer chuck installation with the measuring holes aligned parallel to the flow to minimize backscattering.

Protect the M16 cable outlet

For the M16 connector, leave at least 70 mm of outlet clearance to prevent cable damage from excessive bending.
