Field Transmitter is a Rosemount 3300 measuring level and oil/water interface. sending a 4-20mA to our Honeywell 3000 DCS. We are using a (Rosemount) HART Tri-Loop to convert the digital signal to a second 4-20mA. The use of the (recommended) MTL 7206 seems to 'block' the digital signal. The circuit is I.S. Tried MTL 728/707 but, still had problems. Any suggestions???
