- Economy-priced probe with integrated measuring transducer for measuring filling level e.g. in tanks, cisterns or waters. Connection to ZIEHL-Web-Relay TR800Web for monitoring and logging of filling levels. Alarms by emails when levels are reached, e.g. before tank is empty. Monitoring and display of levels with Digital Panelmeters MINIPAN 352 or other devices with input 4-20 mA. The probe for relative pressure is submersible. It is placed at the bottom of the tank and determines the level by measuring the hydrostatic pressure. The result is transmitted via signal 4-20 mA (2 wire). The cable (PUR) includes a pressure compensation capillary that compensates fluctioation of atmospheric pressure.
