American Sensor Technologies' AST45TP Liquid Level Sensor
The AST45PT liquid level sensor for hydrostatic level and temperature measurement provides two independent 4-20mA output signals for a level and a temperature signal. With measurement ranges from 1 psi (27.68-in. water column) to 100 psi (230.67-ft water column), the AST45PT appeals to a wide range of applications. AST offers five temperature ranges and eight cable length options to make integration simple.
