the electrode is again covered with fl uid, the error message
disappears and the meter continues measuring.
Amplifi er Mounting Confi guration Options
Two amplifi er-mounting confi guration options are available
to meet a variety of meter placement and environmental
conditions.
Meter Mount Confi guration
The Meter Mount confi guration has the amplifi er mounted
directly on the detector. This compact, self-contained
confi guration minimizes installation wiring.
Meter Mount
Remote Mount Confi guration
Remote Mount confi guration places the amplifi er and its
functions at a location separate from the fl uid fl ow and
detector. This confi guration is necessary in situations where
process fl uid temperature or environment exceeds amplifi er
ratings. A remote mounting bracket is supplied.
Detector and amplifi er are connected by wires, run through
conduit, between junction boxes on the detector and remote
mounted amplifi er. The distance between the detector
junction box and amplifi er junction box can be up to 100 feet
(30m).
This confi guration can also provide a more convenient
amplifi er programming and display placement for monitoring
meter readings.
METER/AMPLIFIER LOCATION, ORIENTATION and
APPLICATIONS
Remote Amplifi er Outdoor Location
The amplifi er can be installed and operated outdoors.
However, protection from the elements must be considered:
1. Be aware of the ambient environment and
temperature ratings for the unit -4°F to 122°F (-20°C to
50°C).
2. If an indoor location is within 100 feet (30m) of the
detector installation, consider increasing the cable length
and mounting the amplifi er indoors.
3. At a minimum, fabricate a roof or shield over and/or
around the amplifi er to protect the LCD display screen
from sunlight.
Temperature
To prevent meter damage in any environment, minimum and
maximum temperature ranges must be observed.
1. For remote amplifi er applications, the fl uid temperature
range is -4°F to 248°F (-20°C to 120°C) at a maximum
ambient temperature of 122°F (50°C) for the following
liner materials: PFA and PTFE.
2. For remote amplifi er applications, the fl uid temperature
range is 32°F to 178°F (0°C to 80°C) at a maximum
ambient temperature of 122°F (50°C) for the following
liner materials: Hard rubber and soft rubber.
3. For meter mounted amplifi er applications, the fl uid
temperature range is -4°F to 212° (-20°C to 100°C) at a
maximum ambient temperature of 122°F (50°C) for the
following liner materials: PFA and PTFE.
4. For meter mounted amplifi er applications, the fl uid
temperature range is 32°F to 178°F (0°C to 80°C) at a
maximum ambient temperature of 122°F (50°C) for the
following liner materials: Hard rubber and soft rubber.
5. The ambient temperature range surrounding the amplifi er
is -4°F to 122°F (-20°C to 50°C.)
