8250 ProcessPro® Level Transmitters
Panel Mount
Available with Single or Dual Sensor Input
Description
+GF+
SIGNET 8250 Level Transmitters
are compatible with the +GF+ SIGNET
2450 Pressure Sensor. The instrument is
available in field and panel mount
configurations, single or dual-channel
input and equipped with one 4 to 20mA
output, fully scaleable and reversible for
each input channel. The unit also
features two relays, plus the ability to
support two additional externally
mounted relays (for a total of four). Relay
operation is selectable for High, Low,
Window or Off, and includes fully

adjustable hysteresis and trigger time
delay. The unit also has the ability to
accept other level sensors with 4 to
20mA output via the +GF+ SIGNET
8058 Signal Converter. Automatic levelto-volume conversion allows display and
control of tank level and/or volume in
units such as gallons, kilograms, feet or
meters. Simply enter the dimensions of
your tank or vessel, and the instrument
will calculate volume from the level
measurement.

Ordering Notes:
)Field mount instruments can be
1
mounted with a sensor in an
integral configuration by
choosing the following:
• Order integral adapter kit
3-8052 (sold separately) to
connect the instrument directly
onto the sensor.
• See page xx for more info.
2) An optional splashproof rear
cover can be ordered
separately if needed.
3) Use the universal mounting kit
with the field mount instrument
to mount to a pipe, tank or
wall.
4) Two additional relays can be
used with this product. See part
numbers 3-8059-2 or 3-80592AC (page xx).
5) To mount the panel version on
a wall, use heavy duty wall
mount bracket.
6) Order RC filter kit to protect
relays from voltage spikes.
