The CLD4MT2D230 with Module by Carlo Gavazzi is a level monitoring relay with a conductive fluid level for 230VAC applications. It monitors two stages of level, either high or low. It features two independent relays with adjustable hysteresis and delay, stainless steel protection sleeve, IP67/NEMA 4X, and fixed cable length. This relay is designed for use with conductive non-metallic liquids such as acids, bases, chemicals, and salts. It is suitable for a wide range of applications, including detecting high and low levels, pump control, and overflow prevention.
