Non-invasive temperature measurement

Contents

Connection technologies for temperature measurement

Measuring the temperature of the process or the medium is a common task in the food and pharmaceutical industries. Invasive measurement systems that extend into the process space are typically used for this purpose. This method is tried and tested and robust, but it poses a hygiene risk due to the necessary interfaces with the process.

Clamp-on technology as an alternative to invasive temperature measurement methods

A smart alternative – particularly for sterilisation monitoring – can be to measure the temperature of the pipe surface or tank, thereby inferring the temperature of the medium and avoiding the need to intervene in the process. Labom clamp-on devices are generally quick and easy to install and can also be retrofitted very easily into existing systems. Clamp-on technology is particularly suitable for measuring water and aqueous solutions, as well as saturated steam, in indoor applications. Pharmaceutical plants in particular contain many temperature measurement points that are suitable for measuring surface temperature. Here, the measurement of surface temperatures can demonstrate its advantages in terms of low system costs and flexibility.
