Thermocouple Data Loggers
Thermocouples are a type of industrial temperature sensor widely used due to their versatility, broad temperature range, and relatively low cost. To convert a thermocouple's electrical output into a temperature reading, a device must measure the low-voltage, nonlinear signal and compensate for ambient temperature. This process, known as cold junction compensation, ensures accurate readings.
All of our thermocouple data loggers include cold junction compensation, but depending on the model, they may also offer additional features, including:
-
Display – Some data loggers feature a simple numeric display, while others include a full graphic display with trend and bar graphs.
-
Portability – Fully portable data loggers should be battery-powered. Our portable loggers come with either a replaceable or rechargeable battery.
-
Input Configurability – All of our thermocouple data loggers can be configured for specific thermocouple types, and many models also support sensors beyond thermocouples.
-
Storage Memory – While all thermocouple data loggers include internal memory, some models also support external storage via USB flash drives and/or SD cards.
-
Alarms – Alarm functionality varies by model and may include conditional logging, flashing lights, audible alerts, or relay/transistor outputs. The relay/transistor output can trigger external annunciators or enable the logger to function as a temperature controller.
-
Communications – Our data loggers support a variety of communication options, including wired connections such as USB, RS485, and Ethernet, as well as wireless options like Bluetooth, Wi-Fi, and cellular connectivity.
By selecting the right thermocouple data logger with the features that best suit your application, you can ensure accurate temperature monitoring and efficient data management.
