6685-14-317-0013 6685143170013 143170013 is an instrument that senses, measures and converts pressure of a gas or fluid into electrical signals to be displayed in pounds per square inch (psi) or the equivalent. the item contains an input pressure port, electrical output connection and may include an output pressure port. see also transducer, motional pickup for items with a linear motional input and electrical output to be displayed in other than psi or the equivalent.

6685-14-377-0013 6685143770013 143770013 is an instrument designed to measure air, gas, fluid, and vapor pressure by means of an internal pressure sensitive element (bellows, bourdon tube, transducer/transmitter and the like) which transmits energy, by direct linkage, to the indicating pointer of a scale or a digital display, calibrated in units of pressure.it may include a temperature equivalent scale.for items that do not have an internal pressure sensitive element see indicator, pressure.
