Before deciding on a pressure transducer for their HVAC/R equipment, most OEM design engineers must be mindful of the overall environment of their manufacturing process. Because even though a high quality pressure transducer may be suitable for any given HVAC/R product, its lifespan still depends heavily on the assembly process of the manufacturer. Therefore, every design engineer should understand each and every one of the following five elements when designing his or her manufacturing system before delivering it to the customers.
1. Voltage spikes:
In electrical engineering, voltage spikes take place when there are fast, short duration electrical transients in voltage. Sometimes their causes are difficult to identify, but the most common culprits are usually short circuits, tripped circuit breakers, unexpected failures, or sudden power transitions between equipment on the same power line. Therefore, when installing pressure transducers into their system, design engineers need to be aware of possible scenarios in their environment that may lead to voltage spikes and affect the transducers as a result.
2. Fluorescent lighting interference:
As insignificant as it may appear to be, interference from fluorescent lightning may prevent transducers from being 100% effective. Because this lightning can create a magnetic field, this field can induce voltages to the wires of pressure transducers. In the worst case scenario, the system can misinterpret this as an output signal and malfunction.
Defined as an unexpected impact that transmits relatively high energy within a short period of time, shocks have been known to cause errors for even the highest quality pressure transducers.
Over-pressure can be the result of many things from water hammer to a dysfunctional pressure regulator. Many pressure transducers are designed to perform up to their proof pressure measurement; any degree of pressure passed this point may lead to damage of the transducers, even if the pressures have yet to reach the burst pressure threshold.
It is one of the most basic, yet also most important factor to remember. Pressure transducers can only perform effectively within a certain temperature range, and thus excessive high or low degrees will most likely cause adverse effects to not only the transducers themselves, but also to the entire system as well.
