Signal calculator 5115A
Redundancy measurement with 2 input signals
Signal calculator with the four arithmetical operations
Duplication of the input signal
Input for RTD, Ohm, TC, mV, mA, and V
Universal supply by AC or DC
- Redundancy measurement of temperature by means of two sensors, where the secondary sensor takes over the measurement when a sensor error occurs on the primary sensor.
- Duplication of the input signal, e.g. from a temperature sensor or an analog process signal to two separate analog outputs.
- Signal calculator with four arithmetical operations: Addition, subtraction, multiplication and division.
- Example: Differential measurement:
(Input 1 * K1) - (Input 2 * K2) + K4 - Example: Average measurement:
(Input 1 * 0.5) + (Input 2 * 0.5) + K4 - Example: Different functions on the outputs:
Output 1 = input 1 - input 2, and Output 2 = input 1 + input 2 - Power supply for 2-wire transmitters.
