GF Signet 2250 Hydrostatic Level Sensor - Manual (Page 6)

6 2250 Hydrostatic Level Sensor
4 to 20 mA Loop Wiring
• The 3-2250-21X-X models provide a 4 to 20 mA loop output when powered with 24 VDC.
• Connecting the SHIELD to a direct Earth ground may reduce electrical noise interference.
4 to 20 mA Span
The 2250 is available in two factory-set span ranges:
• Models numbers ending with "U" or "U-1" have a factory span of 0 to 10 psig.
• Model numbers ending in "L" or "L-1" are spanned for 0 to 50 psig.
The chart below lists the factory span of all available models.
The level ranges in meters and feet are based on the mass of water.
