Output
Two-wire 4–20 mA liquid level control signal with digital signal based
on HART protocol.
Power Supply
External power supply required. Controller operates on terminal
voltage of 11–55 V dc.
Humidity Limits
0–100% relative humidity.
Overpressure Limit
0 psia to a maximum of 1,600 psia (11032 kPa).
Static Pressure Limit
Operates within specifications between static line pressures of 0.0 psia
through 800 psia (5516 kPa) maximum.
Load Limitations
Loop resistance is determined by the voltage level of the external power
supply, as described by:
