AST5100 Series Low Pressure DP Transducer


The AST5100 Wet – Wet Differential Pressure transmitter is your accurate pressure sensing device for low differential pressure. With a differential pressure range as low as 0 to 5” water column (12.5mbar), this product can be used to measure flow across an orifice, differential across a filter, tank level, or gauge pressure. Using LVDT technology and AST’s advanced electronics, the AST5100 delivers accurate, repeatable measurements.
