Altronic 691201-100 Pressure Transducer

The Altronic 691201-100 is a robust sealed gauge pressure transducer designed for industrial applications, particularly in engine monitoring and control systems for natural gas, oil, and gas industries. This model measures pressure from 0 to 100 PSI with high accuracy and reliability, making it ideal for harsh environments where precise pressure sensing is critical, such as compressor stations, engine controls, and process monitoring. Key features include a stainless steel wetted parts for corrosion resistance, a compact design for easy installation, and compatibility with Altronic's ignition and control systems. Benefits include excellent repeatability and hysteresis performance, with total error of ±4% full scale, ensuring dependable readings over a wide temperature range (-40°F to 185°F). Compared to similar transducers from competitors like Honeywell or Rosemount, the Altronic offers superior integration with engine-specific systems, reducing setup time and costs, though it may have a narrower pressure range specialization. Drawbacks include the need for specific excitation voltage (4Vdc) and potential limitations in extreme high-pressure applications beyond 150 PSI overload. Overall, it's a cost-effective, durable choice for industrial engine pressure sensing, emphasizing safety and operational efficiency.
