Setra Model 261C: Low Differential Pressure Transducer

The Setra Model 261C is a low differential pressure transducer that delivers high-precision, rapid-response measurements for low-range applications. Specifically designed for HVAC, pharmaceutical plants, and clean rooms, the 261C measures pressure difference or gauge (static) pressure to meet critical industrial requirements. With its excellent performance-to-price ratio, it is a widely used solution for workshops and infectious disease wards.

Key Features

• High Sensitivity: Capable of measuring pressure ranges as low as 0 to 25Pa.
• Optional LCD Display: Available with or without a built-in LCD display for on-site readings.
• High Accuracy: Delivers a standard accuracy of ±1% FS, with optional high-accuracy upgrades to ±0.4% FS or ±0.25% FS.
• Selectable Outputs: Provides selectable output signals in 4-20mA, 0-5VDC, or 0-10VDC for flexible system integration.
• Durable Enclosure: Features a die-cast aluminum enclosure with an IP65 protection rating.
• Advanced Sensing Technology: Utilizes SETRA’s variable capacitor sensing technique with a stainless steel sub arc welding sensing element.

Designed for Critical Applications

The Model 261C is an ideal choice for monitoring and control in a variety of sensitive environments, including:

• HVAC Systems
• Pharmaceutical Plants
• Clean Rooms
• Bio-Safety Labs
• Infectious Disease Rooms
• Air Handling Units (AHU)
• Stairwell Fire and Smoke Protection

Reliable Performance

The transducer includes a temperature compensation circuit to ensure stable readings. It operates with a 24VDC excitation voltage, and a 24VAC power supply can be selected for voltage signal outputs. The Model 261C is designed for use with clean air or similar non-conducting gases.
