Monitoring

The CMT Peak Pressure Indicator is an easy, fast and cost-effective way to maintain your diesel engines. It measures the maximal firing pressure and the compression pressure of two and four-stroke combustion engines. It helps to balance and to optimise your engine, and with that, you will be able to make the most out of your diesel engine and fuel. By cutting the fuel for one cylinder for a short time, you can easily detect any possible blow-by to avoid unwanted loss of energy. Optimising your engine cannot be easier with the help of the CMT Peak Pressure Indicator. The Peak Pressure indicator is designed with the engineer on-site in mind. It has been designed for easy operation and to protect its user in case of excessive cylinder pressure. A safety glass gauge and protection by a blow out back wall are just two examples for our features to avoid accidents during the usage. Every single device will be tested and calibrated according to our ISO 9001 quality standards and will be supplied with a calibration certificate proving the accuracy of the instrument.

Newly developed and part of CMT´s new range of Premet diesel performance analysers. The PREMET M is the way to go if you are looking for an economical approach to monitor your engines without sacrificing quality and accuracy. Designed by marine engineers to be used by marine engineers. The PREMET M helps to balance cylinder load, optimise injection timing and detect worn or damaged engine components and thus reducing the engine™s operating cost. Balancing the cylinder load helps extend engine life, increases efficiency, and reduces emissions to assist with environmental compliance. Proper ignition timing reduces exhaust gas temperature and the rate of excess carbon build-up. Tuning the engine may reduce specific fuel oil consumption (SFOC). For each degree that the ignition is retarded, SFOC increases by approximately 2%. The PREMET® M may protect against costly downtime by implementing predictive maintenance. Major defects can be easily detected. Engine maintenance can be planned, thus saving in parts and labour by changing engine parts based on need, not on timed intervals. The PREMET M has a rugged housing and uses a Kistler PiezoSMART pressure sensor of latest design which is being connected to the indicator valve of the cylinder for a measurement. 4-stroke engines can be measured without pick up with high accuracy. The non-volatile memory stores up to 18 engine records with up to 20 cylinders per engine. The angle precision of the PREMET M is 0.17 deg. The max. cylinder pressure the sensor can be used with is 350 bar. The PREMET M is compact, easy to use and very intuitive. Data is being exported via USB and can be analyzed further with the software supplied together with the device. For personnel managing multiple vessels CMT offers a Fleet Management Software.

The PREMET® diesel indicators are known to be rugged and reliable. The newly developed PREMET® X now adds a brand new software, new sensor technology and connectivity to obtain, show, analyse and export the important pressure data of your diesel engine during operations. This device gives you the opportunity to fine-tune your engine to a higher efficiency resulting in lower costs. Compatible with low-, medium- and high-speed engines the PREMET® X is the perfect system to optimise your fuel injections to reduce fuel consumption but also to avoid repairs and damages as part of a condition monitoring regime. The PREMET® X, Made in Germany, is using high-quality materials and is equipped with the newest PiezoSMART sensor from Kistler Switzerland. Latest designed engines run with peak pressures up to 300 bar and high exhaust gas temperatures. The new sensor technology ensures high performance and accurate results for the complete range. The storage of calibration data inside the sensor makes it possible to easily exchange sensors without calibration of the device. The new software allows doing an in-depth analysis of your engine ensuring you will be in control of the condition of the engine without being an expert user. If your job includes responsibility for multiple vessels the Fleet Management Software will make your life much easier and for worldwide access, CMT is offering a Cloud solution as well. The integrated WiFi connection increases the ease of data transfer considerably. A WiFi network with an internet connection, which can easily be established with a standard mobile phone in the next port will allow an automated upload of the data into the cloud. The large internal memory of the PREMET® X allows saving as many engine setups as you like up to 40 cylinders per engine. The integrated compensation of torsional vibrations enables ultra-accurate measurements for 2-stroke engines. 4-stroke engines can be measured with an extra TDC sensor with high accuracy. Using an acoustic emission sensor the fuel injection can be monitored with no need to tamper with the high-pressure fuel lines during installation. Ignition delay and other critical timings during combustion will become visible.

Most engineers are familiar with the importance of regular checks on diesel engine crankshafts and cylinder liner. The old dial gauge for crankshaft alignment checks was time-consuming, unpleasant, dirty and gave uncertain accuracy. By using Prisma Tibro™s electronic Deflection Indicator DI-5 series, the task will be much more comfortable, and the accuracy will be improved. As an option to the instrument, you can connect the ovality kit to check the cylinder liner ovality and wear comparison. The Deflection Indicator DI-5 series has been used by large numbers of engineers in over 90 countries worldwide. Four push buttons on the DI-5C panel are used to select, change and accept values on the display such as temperature, engine number, number of cylinders, measurement direction, and so on. Just push the OK button to store the value. On completion of the first cylinder, move the transducer to the next cylinder and store measurement values. The generous measurement range allows the transducer to be moved between cylinders without mechanical adjustment. When all cylinders are completed soft copy can be downloaded to a PC for reference and future comparisons.
