RT721 Programmable RTD Temperature Transmitter
Brand: Intempco Controls, IncThe RT721 is a low cost three-wire transmitter that converts a Pt100 ohm input to proportional voltage signal.
The transmitter provides sensor excitation and includes linearization, lead wire compensation, and lead-break detection functions.
Setup and calibration are made with a USB connection to your PC and Intempco’s configuration software.
Advanced signal processing capabilities and variable range input make this instrument very suitable for the most demanding temperature measurement applications.
Features- Easy setup, digital calibration and fully field re-programmable via USB module and PC Windows based software
