What are the key considerations when selecting harsh environment sensors?

When selecting sensors for harsh environments, key considerations include durability, material compatibility, accuracy, and reliability. Sensors must withstand extreme temperatures, pressure, humidity, and corrosive or abrasive substances, necessitating robust materials like stainless steel, ceramics, or specialized polymers. Accuracy and stability are critical, as environmental factors can affect sensor performance. Additionally, the sensor's ability to maintain reliable data transmission in challenging conditions is crucial, requiring protection against electromagnetic interference and robust housing. Power consumption, ease of maintenance, and compliance with industry standards are also important to ensure long-term functionality and integration into existing systems.
