Power consumption AC: <15 VA (including sensor)
DC: <15 W (including sensor)
Switch-on current:
• max. 13.5 A (< 50 ms) at 24 V DC
• max. 3 A (< 5 ms) at 260 V AC
Power supply failure Lasting min. 1 power cycle
• EEPROM or T-DAT saves measuring system data if power supply fails
• S-DAT: exchangeable data memory which stores the data of the sensor (nominal diameter, serial
number, calibration factor, zero point, etc.)
