Schleppzeiger, eingerichtet zum Berechnen einer Prozessmessgröße, aufweisend eine Recheneinheit zum näherungsweisen Berechnen einer vergangenen zeitlichen Entwicklung des Wertes der Prozessmessgröße aus Prozessmessdaten eines Messgeräts, sowie zum Be...

The invention claims a method for ensuring the operational readiness of a battery, in which the battery is first electrically connected to a test device, then tested with the test device to determine whether the battery is passivated. If the battery is pas...

The power supply (1) has a solar cell (3) with a variable output voltage for a field device (7). An accumulator (9) is charged by a charging circuit (5), which is formed as an integrated circuit. The charging circuit is switched in a state, in which the ou...

The system has a radio module (2) and power supply unit (3) which is with a field device (1). A power supply adapter (10) is provided an energy transmitter (11) for the wireless transfer of energy to the power supply unit. The power supply unit is provided...

The method involves scanning (601) portion received signal of the level sensor at discrete times. The samples of the sampled received signal are converted into digital samples. The new value for a digital sample of the first digital samples is calculated (...

The field device (10) has input protection unit (101), energy storage unit (105), electrical consumer, charging circuit and charging current control unit. The charging circuit is operated, such that the energy storage unit stores the supplied energy. The c...
