The MBS 3000-1211-A1AB04-0 is a type of Danfoss pressure sensor. This part is a highly accurate, piezoresistive sensing element that can measure and output changes in pressure or differential pressure. It is made of a stainless steel diaphragm and is encapsulated in a rugged, weather-proof housing. This sensor also features temperature compensated ASICs, output calibration, and a wide range of temperature range and connection options. The Danfoss MBS 3000-1211-A1AB04-0 device is typically used in applications requiring precise pressure and differential pressure measurement, such as agricultural and automotive systems, industrial machinery, ventilation systems, and HVAC systems.
