ATLANTA, Oct. 23, 2006 – Siemens Energy & Automation, Inc. announced the introduction of a new acoustic diagnostics system for preventive maintenance on oscillating positive-displacement pumps. The Sitrans DA400 acoustic diagnostic system continuously monitors pump status and detects even the smallest leaks on pump valves.The Sitrans DA400 is comprised of four acoustic sensors mounted on the pump and a diagnostics device connected to the sensor by up to 65 feet of cable.
With continuous online monitoring, the ultrasonic acoustic sensors detect cavitation generated by the pump suction and discharge valves. The measurement results are displayed on the diagnostics device, or can be transferred to the control room over Profibus, and analyzed in a control system like Simatic PCS 7. Any drop in pump efficiency is indicated, preventing unnecessary plant shutdowns.The Sitrans DA400 system is suitable for all oscillating positive-displacement pumps used in mining, chemical/petrochemical industry, and sewage treatment to pump fluids containing impure solids such as sludge. The diagnostics device is rated IP65 and can be operated between -4°F and +140°F, The sensor is rated IP66/68 and operates between -40°F and +230°F.
