The relay operates when the level drops below the min. level sensor. The relay releases if the level rises above the max. level sensor. Single level control is obtained by connecting the max. level sensor only. ELD Relay for the control of discharging of conductive liquids. The relay operates when the level rises above the max. level sensor. The relay releases when the level drops below the min. level sensor. Single level control is obtained by connecting the max. level sensor only. Level Setting Setting of level on absolute scale, 10-100 k.
