Pressure Sensor - Custom Signal

Job ID: 33106753

Budget: $750 – $1,500 CAD

I'm looking for a pressure sensor 24VDC, 4-20mA. But I want to add/change the analogue so it also carries a sensor ID. It will have a 0.5 sec pause, then 0.5 sec ID analogue signal then 3 seconds of true pressure signal. The ID signal will be a certain signal level which can be program before shipping to customer. I am looking for circuit diagram for manufacturing.
