The sensing and measurement of physical quantities through small changes in electrical capacitance is scarcely a new concept. The natural benefits of this approach were recognized for many years. But it was not until Setra engineers introduced new materials, new designs, and innovative, dedicated circuitry that the techniques full potential was realized in the practical, real world of pressure measurement.

Here at Setra we realize that each customer is unique and every application has different requirements that necessitate different features in a pressure sensor. We have the best interests of the customer in mind and realize we may not have the best sensor for a particular situation.

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.

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.

Traditional vs. Remote Sensor Installation

To better understand the labor and material savings made possible by remote sensors, it is important to compare the traditional method of installing differential pressure transmitters with the new method of installing remote sensors. On a typical job using the conventional method, the mechanical contractor first installs taps with shutoff valves—usually a ball or petcock valve—in the desired locations in the mechanical piping.

After reviewing the top 5 product considerations (pressure, media, temperature, and environment) in which the pressure transducer will be installed, it’s time to look at transducer construction, circuit design and the pressure transducer manufacturer's supply chain.
