Outputs:
Measurement output
Industrial standard current-loop
in the nominal range 4 mA to 20
mA. Normally this will linearly
represent the measured liquid
level, but may be recongured
to match non-linear tank proles
and to be any range within the 4
to 20 mA range.
The power supply –ve is the
return path for the output
current.
The resistive output is designed
for direction connection to a
level gauge. The output is
congured as a nominal 10 Ω to
180 Ω but should be re-
congured to suit the tted
gauge and the installation
arrangement.
Output Resolution:
Measurement output
Voltage output representing
measured liquid level. Normally
this will linearly represent the
measured liquid level, but may
be recongured to match non-
linear tank proles and to be any
range within the 0.5 V to 10 V
range.
Note: output voltage must be
congured to be less than the supply
voltage.
Output impedance: 500 ohms
Recommended load resistor
>=10 kΩ.
Step size < 0.1 mA.
Note: The measurement resolution is
less than this.
Step size < 10 mV
Note: The measurement resolution is
less than this.
Step size < 0.2 Ω
Note: The measurement resolution is
less than this.
Tolerance: +/-10% of the full scale value.
Output Rate:
Measurement output >= 10 Hz
Outputs:
Error
Error is reported as a 2.5 mA
output current.
Not applicable.Error is reported as a 0.25 V
output voltage.
Outputs:
Switch output
Conguration Interface:
Mounting:
Zero-volt switch output that is connected to the –ve power supply when the switch is turned on.
Maximum ‘o’ voltage : 32 V
Maximum ‘on’ current: 150 mA
The switch output may be congured to measure any liquid level threshold and may switch “on”
when the level is either greater or less than the threshold level.
Standard 1.25” BSP thread.
5-bolt SAE adaptor available as an optional extra.
USB micro-B connector under a cover in the cap of the sensor. See the section “Conguringthe sensor” for detailed information.
Note: The default settings may vary
between gauge manufacturers. In this
instance, use the custom conguration
option in GSlevel to set empty, mid and
full scale outputs.
