The Setra 269 Differential Pressure Transducers converts pressure the difference to a proportional electrical output for either unidirectional or bidirectional pressure ranges. The 269 Series is offered with a 4 to 20 mA analog output.

Designed specifically for high performance applications, these transducers are capable of measuring pressures and flows at greater resolutions in critical environments.

The 269 Series transducers are available for air pressure ranges as low as 0.1 in. W.C. full scale. Static standard accuracy is ±0.25% full scale (terminal-based) in normal ambient temperature environments. The units can be temperature compensated to 0.01% FS/°F thermal error over the temperature range of 20 to 140°F.

The Model 269 utilizes 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. The tensioned sensor allows up to 2 PSI overpressure (range dependent) with no damage to the unit.

Applications include critical environments, clean rooms, isolation rooms, room pressure monitoring, and environmental pollution control.
