DESCRIPTION
The Siemens 590 Series Very Low Differential Pressure Transducers sense differential or guage (static) pressures and convert pressure difference to a proportional electrical output. The 590 Series is offered with a 0 to 10 Vdc or 4 to 20 mA output.

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

Short Description 590-781 - Differential Pressure Sensor in Conduit Box, 0.4% FS, 0.65-in WC, 4 to 40mA output.
Features/Specifications:

The 590 Series Transducers are available in five (5) 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.
The 590 Series uses an improved all stainless steel micro-tig welded sensor. The tensioned stainless steel diaphragm and insulated stainless steel electrode, positioned close to the diaphragm, form a variable capacitor. Positive pressure moves the diaphragm toward the electrode, increasing the capacitance.
A decrease in pressure moves the diaphragm away from the electrode, decreasing the capacitance. The change in capacitance is detected and converted to a linear DC electrical signal by the unique electronic circuit of the 590 Series.
The micro-tig-welded tension sensor allows up to 10 PSI overpressure (in either direction) with no damage to the unit. In addition, the sensor parts have thermally matched coefficients, which promotes improved temperature performance and excellent long-term stability.

• 10 psi proof pressure on all ranges.
• 24 Vac excitation.
• 0 to 10 Vdc and 4 to 20 mA 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 improves variable air volume system performance.
• Meets CE conformance standards.
• No field calibration or adjustment necessary.
