Temperature Q&A with J.R. Madden: Accurate Differential Temperature Readings

Temperature Q&A with J.R. Madden: Accurate Differential Temperature Readings

Q: How do I measure differential temperature very accurately?

A: Whenever accuracy is the goal you want to start with RTDs (temperature range permitting). Many temperature transmitters will accept two RTDs and output the difference between the two inputs. However, if you look closely you will find they only make 3-wire RTD measurements and you may have errors and drifts due to wire length and corrosion build up over time.

Mounting Options for the WORM

Mounting Options for the WORM

The WORM Flexible Temperature Sensor solves many installation problems associated with rigid temperature sensors. The WORM is simple to install and can be trimmed to fit into almost any application. It also can bend to accommodate awkward mounting positions and locations and it is completely embedded in the thermowell to ensure no outside influences affect the temperature measurements.

Multiple mounting possibilities are available which also help to make it easier to install the WORM in almost any application where a skin (surface) temperature measurement is required. The new RTI-4 datasheet highlights some of the mounting options that can help to solve real-world installation problems:
