INSTALLATION
1. Location: Select a location where the temperature of the unit will be between
0 and 200°F (-18 to 93°C). Distance from the receiver is limited only by total loop
resistance (see electrical connections). The tubing feeding pressure to the \
instrument can be practically any length required, but long lengths will increase the
response time slightly. Mount the instrument in a location that will not be subject to
excessive temperature, shock, or vibration.
2. Position: A vertical position is recommended (pressure connections pointing
horizontally) since that is how all standard models are spanned and zeroed at
the factory. They can be used at other angles, but may require nal zeroing. Due
to potential condensation buildup that may travel down conduit or cable and into
the housing, it is recommended to install with the electrical conduit or cable gland
pointing downward.
3. Pressure Connection: Dual 1/4˝ NPT pressure connections are provided. Use
pipe thread sealant tape or other suitable pipe joint compound when making
connection to the pressure source. Avoid excess sealant which could block the
pressure passage. When monitoring liquid pressures, air trapped in the lines can
cause incorrect readings. Bleed ttings or similar mechanisms should be used to
bleed off any trapped air.
Optional 3-Way Valve
For applications where higher line pressures may be encountered at installation or
when it is necessary to remove the transmitter for maintenance without interrupting the
process, the optional three way valve is recommended. (See Figure 1)
