CẢM BIẾN ÁP SUẤT APLISENS MODEL APC-2000ALM

Application

The transmitter is equipped with a configurable liquid crystal display. The housing design allows the display to be rotated 90°,

180° and 270°, the housing can be rotated relative to the sensor in the range of 0 - 340°, and the cable insertion direction can be

selected. The display panel includes buttons for scaling the display and selecting the unit of pressure to be measured.

Pressure transmitter APC-2000ALM is designed to measure pressure, vacuum and absolute pressure of gases, vapors and

liquids. The measuring element is a piezoresistive silicon sensor separated from the medium by an isolating diaphragm and

manometer liquid. The electrical signal from the sensor is converted into a digital value compatible with the Modbus RTU

protocol. The housing is made of high-pressure cast aluminum alloy or acid-resistant steel with IP66 protection.
