Provides a complete point solution for accurately measuring process temperature without the requirement of a thermowell or process penetration.
- Calculates a repeatable, accurate internal process temperature based on the thermal conductivity properties of the installation
- Simplifies specification of temperature measurement points by eliminating thermowells and wake frequency calculations
- Reduce installation and maintenance costs by eliminating a pipe penetration which requires process shutdowns
- Increases safety and environmental compliance with leak point elimination
A thermowell and temperature sensor assembly is the most frequently used method of measuring a temperature internal to a process. Thermowells allow for direct sensor immersion into a process which helps provide an accurate measurement, but introduces many complex design challenges and risks associated with creating a possible leak point.
A traditional surface sensor measurement can remove the challenges presented by a thermowell by eliminating the need for a process intrusion. Unfortunately, this method comes with its own challenges as it cannot provide an accurate or repeatable representation of an internal process temperature due to various factors that can impact the measurement.
A new surface sensor innovation eliminates the challenges presented by thermowells and process intrusions while providing comparable measurement performance. This new innovation uses a heat flux algorithm that applies known thermal conductivity properties of both the process pipe or vessel and the surface temperature measurement assembly to calculate an accurate and repeatable internal process temperature value.
