Descrição

The TX70 Series 2-Wire Transmitters for thermocouples and RTD’s feature dip switch selection for input type and range. With the thermocouple models, the user may select from J, K or T input with one model, or E, R or S with another. All models feature 80% zero and span adjustability within any user-selected input range. Models are available with any desired input, with either a 4 to 20 mA or 10 to 50 mA output signal.

Ranging Example: the 0 to 500°C range for a type K thermocouple and a minimum span of 100°C, the user may select any 100° span within that 0 to 500°C range, such as 14 to 114°C or 379 to 479°C. Note: 2-wire transmitters are linearized to the voltage signal produced by a thermocouple, and not to the actual temperature.
