⚠️ 6. Considerations When Selecting
Temperature Range – Make sure it fits your process.
Sensor Type – RTD for accuracy, TC for range.
Output Signal – Analog or digital depending on PLC/DCS.
Hygiene Requirements – Select CIP/SIP compatible designs if needed.
Mounting Style – Compatibility with process connection.
Explosion-proof Zones – Use ATEX-rated models for hazardous areas.
