Setra model 31CS is designed for hazardous locations requiring intrinsic safety, top-of-the-line performance, reliability, and stability at an affordable price. The Model 31CS offers exceptional ±0.25% FS accuracy in pressure ranges from 75 PSI to 32,000 PSI and features all-welded stainless steel construction for a robust design and IP67 seal for moisture and humidity protection. The Model 31CS 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 ATEX/IECEx intrinsically safe pressure transducers, refer to Setra’s 31IS and 32IS.


Key Benefits

  • Best in Class Price-to-Performance
    Strain Gauge technology provides a very linear and predictable output signal over a wide temperature range, which enables Setra to provide an inherently stable and accurate sensor element in high volumes and at low cost. The Model 31CS sensor is constructed using a highly sophisticated automation process, where the sensors are manufactured in Class 100 clean room. To ensure best-in-class accuracy and long-term stability, each sensing element is thermally compensated to an accuracy of less than 0.005%o C prior to leaving the clean room for final assembly. Thermally compensating the unit ensures improved accuracy and simplified conditioning of electronics while eliminating the need for calibration over elevated temperatures as a transducer.
  • Unrivaled Quality
    Setra understands the importance of quality in OEM applications, which is why we are always looking for ways to improve the quality rating of our products. Over the last two years, the Model 31CS failure rate is less than 0.1%, a quality rating unmatched by the competition. The worst thing that could happen to an engineer is to shut down their work because of quality issues. Setra takes this seriously, which is why we have worked hard to ensure that product quality issues will never be a concern for our customers.
  • Rugged Design
    The Model 31CS’s compact welded stainless steel design is constructed to protect the sensor in demanding industrial environments. The electrical connectors are tested to an environmental protection specification of IP67, and a robust internal design ensures that the transducers can survive high levels of vibration. A high level of EMC protection allows the transmitters to perform to the most stringent of industrial standards, and all devices are RoHS compliant.
