Italian Seneca Smart Temperature Transmitter - T121

T121 Smart Temperature Transmitter Product Description:
The T121 is an isolated two-wire loop-powered smart temperature transmitter. The input signal can be arbitrarily set via a handheld programmer or computer (specifically for integrated RTD/thermocouple temperature transmitters). It features compact size, light weight, and easy installation. It converts the temperature parameter of the controlled object into an electrical signal, transmits it to display, recording, and control instruments, and performs detection, regulation, and control of the system. It can be directly installed in the junction box of general industrial RTDs and thermocouples, forming an integrated structure with the field sensing element.
