590-500
Used in building energy
management systems, these
transducers are capable of
measuring pressures with the
accuracy necessary for proper
building pressurization and
airflow control. Their 0 to 10
Vdc analog output is
compatible with all energy
management systems.
With 10 psi proof pressure on
all ranges, they are available in
five different air pressure
ranges. Static accuracy is ±1%
full scale in normal ambient
temperature environments.
The units are temperature
compensated to less than
±0.033% FS/°F of thermal error
over the temperature range of
0°F to +150°F. 1% accuracy, or
better, improves variable air
volume system performance.
