Measuring temperature is important both in weather observations and in many industrial applications.
In weather applications such as meteorology, agrology and hydrology, temperature is one of the standard parameters measured.
In industrial applications, temperature is a universally critical parameter. Temperature measurement is important in many applications and across multiple industries, including food and beverage processing, HVAC, laboratories and distribution centers in pharmaceutical, biotechnology and medical device applications, hospitals, blood and tissue storage, chemical processing, automotive and aerospace.
Temperature sensors are one of the most common sensors on the planet; in addition to wide weather measurement network, they are used also in over 50% of all industrial applications.
Different industrial applications require different temperature sensors. The most commonly used sensors are:
For many critical and regulated industrial applications, a device equipped with an RTD is preferred as the most accurate and stable temperature sensor. Vaisala offers devices that use different kinds of temperature sensors depending on the needs of your application.
Temperature sensors are often placed into a thermal buffer to ensure that normal fluctuations in temperature-controlled environments do not cause false alarms.
In this application note, we discuss different types of thermal buffers, the utility of standardizing buffering material, and the option of using time-based buffers (alarm delays) in monitoring software to achieve the same effect – reducing nuisance alarms.
For over 80 years, Vaisala has been pioneering sensor technology, creating industry-best solutions like HUMICAP®, CARBOCAP®, PEROXCAP®, DRYCAP® and others.
