 7-,<376 Select a location where the temperature of the transmitter will be
between 0 and 175°F (-18 to 79°C). Distance from the receiver is limited only by
total loop resistance. The tubing or piping supplying pressure to the unit can be
practically any length required but long lengths will increase response time slightly.
#7;3<376 The transmitter is not position sensitive. However all standard models
are originally calibrated with the unit in a position with the pressure connection
downward. Although they can be used at other angles, for best accuracy it is
recommended that units be installed in the position calibrated at the factory.
#:/;;=:/766/-<376 Use a small amount of plumber’s tape or other suitable
sealants to prevent leaks. Be sure the pressure passage inside the port is not
blocked.

)3://61<2-The maximum length of wire connecting the transmitter and receiver
is a function of wire size and receiver resistance. Wiring should not contribute more
than 10% of the receiver resistance to total loop resistance. For extremely long
runs (over 1000 feet), choose receivers with higher resistance to minimize the size
and cost of connecting leads. Where wiring length is under 100 feet, wire as small
as 22 AWG can be used.
