The Dupont accident theory identifies the relationship of unsafe acts and practices to accidents.

A vibrating element can be used as a density sensor.

An orifice plate is a non -intrusive flow sensor.

Match the flow sensor with its classification. -Electromagnetic

The Bourdon tube uses a vibrating U -shaped tube to measure pressure.

The photo transistors in the light curtain receiver detect only specific pulses at a designated frequency of the sending device.

Gage factor is a ratio of a change in resistance to a change in length.

For energized electrical equipment fires, foam or loaded steam is the recommended extinguishing media.
