It monitors and controls conductive liquids and powders, example maximum and minimum fill level, protection against overfilling and dry running. The 3-probe connections for 2-point and 1-point level control. It has 220VAC to 240VAC supply voltage. General resistance monitoring, example recording temperature limits with PTC (device to IEG 255, VDE 0435 section 303). This device is straightforward to install and safe to use.Features and BenefitsHigh interference resistance of the measuring circuit, which is isolated from the mains Maximum wire length to the probes is 1500m Large setting range between 2kohm and 450kohm which permits differentiation between fluid and foam Adjustable response and release time delay: 0.2seconds to 20seconds Programmable for open circuit operation (without bridge) or closed circuit operation(bridge X1-X2 or X1-COM) Green LED for operation Yellow LED for contact position 1 or 2 changeover contacts Also available with a sealable transparent coverApplicationsLiquid Level Relays (Conductive Level Sensors) are used in a wide variety of applications including waste water management and the monitoring and management of corrosive liquid media and designed specifically to provide for the: Monitoring and control of liquid levels Protection of pumps against dry running Ability to detect liquid leaks in a system Control of media mixing ratios Control of liquid levels General resistance monitoring tasks, e. G. limit temperature detection with PTCCertificationsIEC/EN 60 255 DIN VDE 0435-303 IEC/EN 61 140 IEC/EN 60 947-1 CSA approval IP40 rated
