Workboat Report • Marine Propulsion Volvo Penta Offers Larger Engine Range Sweden's Volvo Penta has introduced a new engine range that significantly expands its power output up to 1,380 kW (1,850 hp) and opens vast new markets for the company's products. The new range will include in-line six cylinder units, and, for the first time for the company, VI2 and VI6 configuration engines. The new range comprises five basic engine sizes, from 24.5 - 65.4 liter displacement. The new engines are designed to be reliable, fuel efficient with low emissions, a suitable power choice for a wide range of vessels from coastal freighters and fishing ves- sels to harbor tugs operating on inland waters. In addition, the engines are reportedly suitable for auxiliary duties. On the table below are the power specifica- tions for the new line. Each engine is available in either single or twin cir- cuit cooling systems, the latter resulting in a small but significant increase in engine output. Except for the D34 diesels, which have a bore of 150 mm and a stroke of 160 mm, all units in the range feature a 170 mm bore with a stroke of 180 or 220 mm. The D25 and D30 are in-line six cylinder engines, Engine Power R1 Power R2 Cyl Displ.

Smart Electronic Level Switch with A/o Moving Parts The Sea Switch Two was designed and patented for all tank applications. The Sea Switch Two offers a reliable solution for liquid level detection and control for cargo, ballast, and storage tanks, without any moving parts. The Sea Switch Two uses a fully static system that is based on the propagation of an acoustic wave into a metallic rod. A piezo-electric sensing element produces a wave along the rod. As the liquid reaches the sensing element the oscilla- tion stops and the alarm is activated. The Sea Switch Two sensor detects high, high- high, or low level in any liquid with an alarm output given by a dry contact or current loop change 6-18 mA. • Easy installation • Self-test built-in • Fully static system - no moving parts s ELECTRONIC MARINE SYSTEMS, INC. 800 Ferndale Place Rahway, NJ 07065 Call today for more information! 732.382.4344 732.388.5111 fax emsmarcon@aol.com e-mail http://www.emsmarcon.com November, 2000 Circle 364 on Reader Service Card Circle 244 on Reader Service Card
