What is the difference between thermocouples, RTDs, and thermistors?
Thermocouples, RTDs, and thermistors are all temperature-sensing technologies, but each serves different application needs. Thermocouples are commonly used for a wide range of industrial processes and are well suited for demanding temperature environments. RTDs are often selected when higher measurement accuracy and long-term stability are important. Thermistors are frequently used in applications requiring fast response times and precise monitoring within a more limited temperature range. Selecting the appropriate sensor depends on factors such as operating conditions, required accuracy, installation requirements, and process objectives.
Can LEP & NEES provide custom temperature sensors?
Yes. LEP & NEES specialize in providing custom-manufactured thermocouples and RTDs tailored to specific customer requirements. Custom solutions can be designed to meet unique process conditions, installation constraints, temperature ranges, and performance objectives. In addition to custom products, they maintain inventory of standard thermocouples, RTDs, thermistors, and thermostats for immediate availability. This flexibility helps ensure customers receive the most appropriate sensing solution for their application.
What temperature sensing accessories are available?
LEP & NEES offer a broad range of accessories that support accurate and reliable temperature measurement installations. Available products include thermowells, protection tubes, wire, terminal blocks, and other sensor installation components.
