Model 31IS Pressure Transducer
Brand: Setra Systems, IncThe Model 31IS is designed for hazardous locations requiring intrinsic safety, top of the line performance, reliability, and stability.
The Model 31IS offers exceptional ±0.25% Full Scale accuracy in pressure ranges from psi: 75 to 32,000 and features an all welded stainless steel construction for a robust design and IP67 seal for moisture and humidity protection.
The Model 31IS offers a variety of different outputs, pressure connectors, and electrical connectors to satisfy the most challenging application requirements. In addition, voltage units are available with a dual pressure/temperature output. For CSA intrinsically safe pressure transducers, refer to Setra’s 31CS and 32CS.
