Function and system design Measuring principle Analog in 1 Analog in 2 A0011762  1 Example of a "differential pressure" application The RMA42 process transmitter powers the transmitter and processes analog signals from transmitters, particularly from the area of process instrumentation. These signals are monitored, evaluated, calculated, saved, separated, linked, converted and displayed. The signals and results of calculations are communicated by analog means, as a switch output and displayed digitally. Measuring system The RMA42 is a process transmitter that is controlled by a microcontroller and features a display, analog inputs for process and status signals, analog and digital outputs, as well as a configuration interface. Connected sensors (e.g. temperature, pressure) can be powered by the integrated transmitter power supply system. These signals are monitored, evaluated, calculated, saved (min/max values) and provided at the various outputs. All measured values, and values calculated in any way, are available as a signal source for the display, all outputs, relays and the interface. It is possible to make multiple use of the signals and results (e.g. a signal source is used as an analog output signal and as a limit value for a relay). Mathematics functions The following mathematics functions are available in the RMA42:

• Total
• Difference
• Multiplication
• Average
• Linearization Linearization function Up to 32 user-definable linearization points are available in the device per calculated value for the linearization of the input, e.g. for tank linearization. In two-channel devices (optional), the mathematics channel M2 can be used to linearize the mathematics channel M1. Linearization is also provided in the FieldCare configuration software.
