Connection method

304XX1: A two, three, or four wire heating resistance sensor

304XX2: A thermocouple sensor combined with a built-in thermal resistance sensor in the transmitter for cold junction compensation, or a fixed cold junction temperature set without a thermal resistance sensor for compensation (compensation accuracy will affect the final measurement accuracy)

304XX3: Adopt WP-304XX1 or WP-304XX2 connection method according to requirements
