Converting mA to voltage is common in HVAC when working with pressure transducers. Terminology to keep in mind includes:

• 1 mA = 0.001 AMP (short for amperes)
• Amps are referred to as CURRENT
• Resistor values are in OHMS (Ω is the symbol for ohms)
• VOLTAGE is the result of passing amps through a resistor

A variety of pressure sensor designs are available today. Two of the most common sensor types are MEMS and capacitive sensors.

Advancements in technology have created a need for enhanced pressure sensing technology, the next generation of pressure transducers. To meet this new demand, we designed the Model AXD™ Pressure Sensor, the updated and improved version of the Model 209. The Model AXD™ Pressure Sensor is built leveraging the strength of the 209's variable capacitance sensor paired with a new electronics platform. With enhanced performance through digital signal conditioning and a rugged, laser-welded construction, the Model AXD™ Pressure Sensor has the reliability and accuracy necessary for industrial and OEM applications.

Industrial spaces include an extensive range of environments. As such, the products used in those spaces are diverse, varying from gauge to compound to vacuum pressure measuring tools. Pressure sensing in industrial applications helps to keep systems working productively. Demanding industrial applications can require customizable solutions for any type of pressure measurement.

Design engineers have a lot to consider when selecting components for use in end-user products and equipment. Original Equipment Manufacturers (OEMs) that follow a strict Design for Manufacturing and Assembly (DFMA) methodology will have few, if any, problems with pressure transducers. However, OEMs that do not adhere to DFMA practices in their factory increase the likelihood of reoccurring issues, including transducer failure.

When first selecting a pressure transducer for a new project or piece of equipment, designers typically focus on key design parameters such as pressure range, electrical output, media compatibility and environmental conditions.  However, those parameters are not the only ones to consider when making a smart choice for an application. There are three design considerations that are often overlooked when selecting a pressure transducer: transfer medium (oil filled vs. non-oil filled), construction, and type of sensing technology.

Setra Systems will be exhibiting at the Automotive Testing Expo 2017 between October 24^th and October 26^th at the Suburban Collection Showplace in Novi, MI.

There are numerous environmental factors that can interfere with the performance of a pressure transducer.  Two commonly overlooked factors are shock and vibration. Knowing the system where the pressure transducer is installed can help avoid high shock and vibration conditions, minimizing premature failure of your instrumentation.
