Dold 多德 MK9151.11 2-450kOhm DC24V 液位控制器

产品详细信息

MK 9151 - level relay The MK9151 is used for Level monitoring and control of conductive liquids and powders, e.g. maximum and minimum fill level, protection against overfilling and dry runningMonitoring and control of the mix ratio for conductive liquidsGeneral resistance monitoring, e.g. recording temperature limits with PTC (device to IEG 255, VDE 0435 section 303) Features 3 electrode connections for 2-point and 1-point level controlThe metering circuit galvanically isolated from the mains is immune from high levels of interferenceMax. lead length to the electrodes: 1500 mWide setting range: 2 → 450 kΩ which enables differentiation between liquid and foamAdjustable response and fallback delay: 0.2 → 20 sProgrammable for working current principle (without bridge) or rest current principle (X1-X2 and/or X1-COM bridge)2 LEDs to indicate operating readiness and contact position1 changerOverall width 22.5 mm, protection class IP40 液位继电器用于监测导电液体的液位，且提供向上/向下、最小、最大和灌注/排空变型。
