Resistive temperature device (RTD) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. They are usually made of metallic elements or alloys such as copper, nickel, or nickel-iron.
Clinometers or inclinometers can indicate the angular variation or inclination from horizontal. Laser levels project a spot or indicator onto a surface that is level with the projecting laser level. Machinist's levels are smaller and provide a higher degree...
Thermistors are thermally-sensitive devices whose electrical resistance varies with temperature. Unlike RTDs and thermocouples, thermistors do not have standards associated with their resistance vs. temperature characteristics or curves.
Shipping and Handling Labels are preprinted labels that identify proper handling directions and in some cases destination information. These labels may indicate contents of package such as Flamability or Fragile or they may indicate directions for handling.
