Each sensor can be non-electrical and can be adapted to interact with the equipment and generate at least a first sensor output and second sensor output. The first sensor output can be indicative of a first equipment state and a second sensor output can be indicative of a second equipment state. The system can also include at least one converter disposed outside the hazardous area. Each converter can be in communication with at least one of the sensors. Each converter can be configured to receive the first and second sensor output and generate a converter output signal based on at least one of the first and second sensor outputs.
