Setra's NEW Industrial Catalog

The new 2014 Industrial Product Catalog is a comprehensive guide that contains the technical data sheets for products commonly used in Industrial applications.

• Section 1.1: General Purpose OEM
• Section 2.1: Test & Measurement
• Section 3.1: Sanitary Pressure
• Section 4.1: Accelerometer
• Section 5.1: Barometric Pressure
• Section 6.1: Very Low Differential Pressure
• Section 7.1: Power Monitoring

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.

Setra Model 3550 - Compact Low Pressure OEM Pressure Transducers

The 3550 is perfect for OEMs that need consistent high levels of performance, reliability and stability because of the units small package size with all 316L stainless steel wetted parts at an unbeatable price performance ratio. A wide choice of electrical outputs as well as both electrical and pressure connections means the unit is suitable for most applications without modifications. 

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.

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.

On the heels of an economic crisis, the President of the United States signed the American Recovery & Reinvestment Act (ARRA) in 2009 with the goal of:

Capacitive pressure transducers have earned a reputation for consistently high accuracy and unmatched long-term stability. These sensors find broad application in areas where characteristics rate from important to vital. A few of these include:

Capacitance based pressure transducers provide many benefits over other technologies. 8 features that should be considered when choosing a pressure transducer are accuracy, minimal mechanical motion, range capabilities, long term stability, high-level output, media compatibility, electromagnetic compatibility and resistant to harsh environments..
