Cylinder Liner Temperature Sensor (CLTS)

The Cylinder Liner Temperature Sensor (CLTS) from Dr. E. Horn consists of the CLTS sensor TGL 00942 with an evaluation board in housing GHG 02731. This system continuously measures the temperature level of each liner in the marine engine aggregate.

The CLTS has many advantages:

  • Accuracy
  • Guaranteed contact with medium
  • Withstand harsh environment.

We deliver directly and globally to end-users, agents, and resellers.

Working principle of the CLTS

Cylinder Liner Temperature Sensors continuously monitor the temperature levels of each liner within a marine engine assembly. The objective is to identify potential issues early on and safeguard the cylinder liner from irreversible harm.

Each liner will be outfitted with a pair of sensors, positioned in opposite directions. This arrangement aids in determining the most critical temperature level, regardless of installation tolerances and any air gaps present within the liner.

The sensors possess a highly rugged design, with the sensor tip capable of enduring temperatures up to 800°C, utilizing stainless steel materials. A spring mechanism inside the sensors allows for movement of the sensor tip, ensuring constant mechanical contact between the sensing element and cylinder liner. This ensures excellent thermal response and swift reaction times in case of overheating.

CLTS sensors come equipped with an evaluation board enclosed in housing GHG02731. Communication capabilities include a current loop of 4...20mA or I²C. This versatility makes the CLTS system suitable for monitoring temperatures in various applications, such as large gear units, plain bearings, and heavy-duty drives.

Adjustment of the Sensor System

A principal adjustment of the CLTS sensor system can be done as shown in the picture below.

The numbers indicate the following:

  1. Cylinder liner
  2. CLTS-TGL00942 Sensor

  3. Signal converter box, which is not mounted directly on the cylinder liners. The Mounting positions is chosen according to cable length and the situation at your site.

 

From Failure Prevention to Performance Optimization

Yesterday’s challenges were about preventing failures - today, the focus is on higher standards. With smaller crews, preventive maintenance is more critical than ever, while predictive maintenance relies on standardized data exchange across automation layers. 

Enhance this by integrating multiple measurement methods, ensuring higher data quality and faster response times. These monitoring systems use multiple microcontrollers to separate collected and transmitted data, strengthening cybersecurity.
