CONFIDENTIAL
Microwire Temperature Sensing Systems
• Features
– Self-Calibrating Sensor -- During The Process
• This is a Process Sensor – We Assume That The Sensor is
Embedded In a Place Where Actual Temperature Is NOT
Measured By Any Other Sensor – Thus No Way To Know
Starting Temperature
– Non-Linear Temperature Accuracy
• More Accurate Near Curie Temperature (216.5C/422F) Than Far Below
It ( 175C – 216.5C, +/- 2C, 150C - 175C, +/- 3C, 61C-150C, +/-4C)
– Polling Rate
• Approximately One Per Second

Why the Growth in Industrial? Reduced wiring complexity
Cuts commissioning time
Eliminates wire and connector integrity issues
Solves electrical isolation challenges
Fewer tripping hazards
No trenching or breaking concrete
Simplified trouble-shooting
Not tethered by the wire - flexibility (add/move/change)
Lower cost on long wire runs
Can be applied where traditional devices are not feasible

Things to Consider • Look for solutions that provide device diagnostics
• Consider mounting locations for best signal strength
• Look for self healing network (retries)
• Look for standards-based encryption
• If considering WiFi, discuss with IT first (who controls?)
• Understand difference between Security and Interference
• Easy to commission with set-up tools and diagnostics
• Not all wireless is the same – try them first
• Automatic field pairing and diagnostic information
• Ensure RF used is globally license-free
• Configurable to interface with standard controllers
• Low power
• Consider trade-offs between a packaged device, and interfaces that require additional packaging
• Consider EMI/EMC requirements. Require test data.
• Look at sealing and temp ratings of the field devices
• Mesh network verses Point-2-Point
• Differentiator for wireless many times is the end user
