Very Low Differential
Pressure Transducers

590 Series

Very Low Differential Pressure Transducers.

Description

The Very Low Differential Pressure Transducers sense
differential or gauge (static) pressures and convert
pressure difference to a proportional electrical output.
The 590 Series is offered with a 0 to 10 Vdc output.

Used in Building Energy Management Systems, these
transducers are capable of measuring pressures with the
accuracy necessary for proper building pressurization and

air-ow control.

The 590 Series Transducers are available in ve 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.

Features

• 10 psi proof pressure on all ranges

• 24 Vac

• 0 to 10 Vdc analog output is compatible with all energy
management systems

• Fully protected against reverse wiring

• Internal regulation permits use with unregulated
DC power supplies

• 1% accuracy, or better, improves variable air volume
system performance

• Meet CE conformance standards

• No eld calibration or adjustment necessary

Applications

The Very Low Differential Pressure Transducers are used

for the following applications:

• Heating, Ventilation and Air Conditioning (HVAC)

• Energy Management Systems

• Variable Air Volume (VAV) and Fan Control

• Environmental pollution control

• Static duct and clean room pressures
