Problem No. 37: Faulty reactor pressure transmitter

Pressure transmitters have become essential parts of virtually all urea plants. Pressure measurement undoubtedly forms an important measurement in industrial process measurement and control. Pressure transmitters convert an applied pressure into an electrical signal, which is then transmitted to a device such as a computer, programmable logic controller, recorder, or digital meter to analyse the electrical signal and utilise it to display, record, or modify the device’s pressure. A schematic of a pressure transmitter is shown in the picture below.
