A load cell is a type of force sensor and it has a direct relationship to pressure, since: pressure = force/area Eq. 1 The load cell’s electrical output is proportional to the mechanical force applied to it. The force can be hydraulic or pneumatic and the transducer is normally based on strain gauges. Other types […]

Understanding the Infrared Temperature Sensor
The infrared temperature sensor appears to be rather straightforward: point, press the button and read the temperature. However, measurement results will be quite disappointing without a thorough understanding of the instruments’ principle of operation and specifications. Temperature measurement instruments can be divided into contact and non-contact types. An infrared temperature sensor used in contact-type instruments […]
RTD temperature sensors: How are they designed?
Analyze the RTD’s strengths and weaknesses with respect to the application before making a selection. The application ultimately determines the RTD’s specifications. Watlow’s RTD sensors are designed to ensure precise and repeatable measurements as well as meet environmental requirements for each application. A high signal-to-noise ratio output increases the accuracy of data transmission and permits greater […]
