590-500 - Siemens - Conduit Assembly Kit for Setra Differential Pressure Sensor

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.
