TAD181 is a hygienic temperature transmitter with integrated drift detection for demanding process applications. It uses a longer 87.5 mm sensing arrangement for deeper temperature measurement. The transmitter combines process temperature measurement with continuous sensor-health monitoring. Its dual sensing concept provides backup measurement capability if one sensing element fails. IO-Link provides digital configuration and diagnostics for high process reliability.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
TAD181 is designed for hygienic applications where temperature measurement must remain reliable over long production cycles. The sensor uses Pt1000 and NTC sensing elements in a thermally coupled configuration. This allows sensor diagnostics and backup measurement. A 4–20 mA output communicates process temperature while the diagnostic output reports sensor condition. Its robust hygienic construction supports demanding process environments.
The transmitter compares the sensing elements to identify abnormal behaviour. Drift warnings and alarms can be configured. Backup measurement helps maintain temperature information if one element fails. IO-Link provides detailed diagnostic and parameterisation functions. This makes TAD181 suitable for predictive maintenance strategies.
