A monitoring system for a hydraulic fracturing pump may include a sensor configured to output a signal based on measurements of a fluid parameter relating to the hydraulic fracturing pump, where the signal has a fixed relationship to a measurement scale. The monitoring system may include a first data receiver and a second data receiver configured to derive the measurements of the fluid parameter using the measurement scale. The monitoring system may include a signal distribution device, without external power, coupled to the sensor, the first data receiver, and the second data receiver. The signal distribution device may be configured to distribute respective input signals to the first data receiver and to the second data receiver, where the respective input signals are based on the signal and have the fixed relationship to the measurement scale.
