How Do Shock & Vibration Affect a Pressure Transducer?

Shock & vibration are two potential mechanical problems for pressure transducers.

Shock is a sudden, unexpected impact that transmits energy to a device in a relatively short time interval. For a pressure transducer, that energy passes through the stainless steel up through the housing. Shock may originate from rough transportation and handling, such as by trucks, forklifts and conveyors. Alternately, shock can be caused simply by dropping the transducer on the shop floor or by an assembler slamming a cabinet door adjacent to it. A transducer may not be damaged by a single shock, but can experience fatigue failure with numerous low-level shocks over the course of its life.

Will Extreme Temperatures Cause Transducer Failures?

Excessively high temperatures are a common source of pressure transducer difficulties.

Like most other electronic equipment, pressure transducers are effected by temperature, shock and vibrations. They consist of numerous components that only function within specified temperature ranges. Transducers exposed to temperatures exceeding those ranges during the assembly process can be adversely affected.

Application Note: Liquid Level Measurement

Liquid Level

The pressure measured at the bottom of a liquid filled tank is proportional to both the height (head) and density of the liquid. For best results the pressure should be sensed by a pressure transmitter mounted at the lowest point possible on the tank, as shown in Figure 1.
