Level and temperature switch NT 61Connecting flange as per DIN 24557 T2Proven and tested highly dynamic float systemapplicable up to 230 Vup to 4 level contactsTemperature monitoring as switch, Pt100 or 4-20 mA outputLevel and temperature switch with display NT 61DConnecting flange as per DIN 24557 T2up to 4 programmable temperature switch pointsalternatively, a continuous temperature signal (configurable to current or voltage) plus one freely programmable switching outputCharacteristics of switching outputs configurable as window or hysteresisTwo switching outputs configurable as frequency output (1-100 Hz)In hydraulics and lubrication technology the liquid level of oil tanks must be monitored. In the process, modern factory automation requires the provision of compatible signals. Despite central system control, visualising the current level on the actual tanks is often desired.
