The Setra 269 Series stands out as a differential pressure sensor crafted to precisely measure and convert differential pressure into electrical output. Offering options for both one-way and two-way pressure ranges, this series provides 4-20 mA analog outputs, catering to diverse applications, particularly in building energy management systems.

Featuring a broad pressure range from 0.1 in.W.C. to 100 in.W.C., the 269 Series ensures accuracy with a standard static accuracy of ±0.25% FS at room temperature and minimal thermal drift of ±0.02% FS/°C post temperature compensation between -7°C to +60°C, ensuring consistent and precise readings.

The Model 269 showcases an enhanced sensor design, incorporating all-stainless steel inert gas protection via argon arc welding. Its structure includes a robust stainless steel membrane and a fixed stainless steel electrode forming a variable capacitor. Pressure alterations prompt diaphragm movement, altering capacitance. Setra’s innovative electronic circuitry converts these capacitance changes into linear DC signals. Withstanding overpressure of 2 PSI in any direction without damage, the sensor ensures durability and reliability.

The Setra 269 sensors find utility across various industries, including pharmaceutical workshops, cleanrooms, isolation rooms, critical position pressure monitoring, HVAC systems, energy management systems, variable air systems, fan control (VAV), environmental pollution control, laboratory and fume hood control, oven pressurization, and furnace ventilation control.

Advantages of the Setra 269 Series include full-scale 10 PSI overload capability, easy rail mounting installation, accessible pressure and electrical interfaces, compatibility with all energy management systems via its 2-wire 4-20 mA analog output, miswire protection, operability with unregulated power supplies, UL94V-0 certified flame-retardant casing, and compliance with CE and FDA standards.

With its dependable performance, versatile features, and adherence to industry standards, the Setra 269 Series emerges as an optimal choice for precision pressure monitoring and control across a diverse array of applications.
