NF – RSJr

GENERAL

• NF RS wired fuel sensor is a level sensor which measures the level of fuel and the temperature of the liquid in the tank. The measurements are transmitted via RS485 wired bus.
• It’s electronics is based on a powerful microprocessor technology and the measurements are accurate and sensitive.
• Measurement accuracy: +/- 0,5 mm.
• Measurement resolution: +/- 0,05 mm.
• Temperature accuracy: +/- 0,2°C.
• It is intrinsically safe suitable for 0 zone, hazardous areas.
• Full stainless steel execution.
• Ultra compact design.
• Measuring range 0,4 m up to 5,5 m.

ENVIRONMENTAL

• Operating Temperature Range: Tamb = -40 +80°C

COMMUNICATION

• Baudrate : 9600
• Databit : 8
• Stopbit : 1
• Parity : None
• Transmission is wired, maximum transmission distance: up to 1 Km based on standard of RS485 interface with proper data cable.
• Proprietary Rs485 data protocol.
• The serial number is unique and corresponds to the probe address for the consequent configuration into the electronics control.

ELECTRICAL

• Ultra low power mode
• Nominal power supply 12 Vdc (30Vmax) through an intrinsically safe barrier.
• Consumption in normal functioning <15 mA @ 12 Vdc(25mA LPM)
• Consumption in sleep mode functioning < 200 uA @12 Vdc
• Ui = 30V
• Ii = 100mA
• Ci = trascurabile/negligible
• Li = trascurabile/negligible
