The Model 276 is an extremely accurate and stable transducer based on the proven SetraceramTM sensing element. The glass fused ceramic capacitive sensing capsule is the heart of Setra’s environmental pressure transducers because of its inherent thermal stability, low hysteresis and fundamentally, simple design. Another major feature of the 276 is Setra’s
custom Application Specific Integrated Circuit (ASIC). The ASIC works hand-in-hand with the SetraceramTM sensor to achieve long-term stability and high accuracy, unmatched by other manufacturers – even at a much higher cost. The ASIC circuit allows the 276 to operate with an excitation as low as 5 V DC for remote battery or solar powered applications.
