KMW Enhances Cylinder Pressure Sensor

Germany's Kaufbeurer Mikrosysteme Wiedemann (KMW) has introduced a higher performance version of its Z01 sensor for measuring cylinder pressure in large diesel, gas and dual-fuel engines.“The further developments center on the measuring capability, accuracy and robustness of our Z01 sensors,” KMW project manager Daniel Maaß explains.“To facilitate the measurement of higher combustion pressures and to contribute to overall robustness, we have increased the temperature resistance of the sensing elements we use in the Z01 sensors. At the same time, new connection technology aims to improve overall resistance to both temperature and vibration.

Tech File: New Cylinder Pressure Sensor Helps Optimize Large Engines

(Photo: Kistler)

The shipping sector is constantly striving to optimize the efficiency of large engines. This endeavor calls for new approaches and innovative products. Each percentage point of efficiency gained here has an immense impact on fuel consumption and emissions. Kistler responds to the trend toward higher cylinder pressures in engines (up to 300 bar) with its rugged, accurate and durable measurement systems. The efficiency of large engines such as those used on commercial vessels can be increased with the help of cylinder pressure sensors that precisely monitor the combustion process.

Lloyds' Alert: Secondary Means of Venting on Tankers

Changes to SOLAS Regulations II-2/4.5.3 (Cargo Tank Venting) and II-2/11.6 (Protection of Cargo Tank Structure against Pressure or Vacuum in Tankers) adopted through Resolution MSC.392(95) will apply to tankers constructed on or after January 1, 2017. The changes mean that these ships must have an independent, secondary means of venting for each tank: that is, a full flow pressure/vacuum (P/V) valve or a pressure sensor that provides an alarm on detecting over-pressure or under-pressure. Note: a pressure sensor is only acceptable as a secondary means if a full flow P/V valve is fitted as the primary means of venting for each cargo tank, as per the arrangement in SOLAS Regulation II-2/11.6.1.2.

Mooring and offloading systems supplier, Offspring International, has announced a rapid response, surge protection system for terminal loading hoses. Called Oiltech Surge Protector, the hose monitoring system offers a smarter and more sensitive way of detecting hose overpressure during tanker loading. If a pressure surge is detected, pumping operations are automatically shutdown. According to the International Tanker Owners Pollution Federation (2013), the highest incidence of tanker related oil spills is during loading operations.

GPS-aided Inertial Navigation System on a Chip

VectorNav Technologies launch the VN-200, high-accuracy GPS-Aided Inertial Navigation System (GPS/INS) on a surface-mount chip the size of a postage stamp. Combining an advanced GPS module with the latest in MEMS inertial and pressure sensor technology, the patent-pending VN-200 provides a coupled position, velocity and attitude solution that is robust to a wide range of static and dynamic operating conditions. The release of the VN-200 GPS/INS marks a significant advancement in the field of inertial navigation. Over the past few decades, the size, weight, power, and cost constraints of typical GPS/INS systems have greatly limited the type and number of end-use applications.

SRM Produces Innovative Three Function Tank Gauging System

Saab Rosemount Marine recently released a new innovative 3-in-1 tank gauging solution–groundbreaking technique for improved performance. The new 3-in-1 solution for level gauging, high level and overfill alarm in one single tank gauge unit has been presented for improved gauging performance and more efficient handling during loading and discharge as well as easier installation. All three functions are for the first time handled by the radar technique, sharing the same deck penetration. Its level gauging, high level and overfill alarm means that all three functions are integrated in one single unit. The functions are designed as independent measuring channels, galvanically separated and intrinsically safe. Saab TankRadar STaR takes advantage of a new sensor technology.
