VDC Reveals Results of Electronic Pressure Sensing Products Study
11/4/2003 - In a market study on electronic pressure sensing products, Venture Development Corporation conducted an extensive Web-based survey with specifiers of these products - end users, OEMs, and systems integrators. The results of these findings are covered in three report volumes, one each for:
- Process Pressure Transmitters
- Non-Process Pressure Transducers & Transmitters
- Component Level Pressure Sensors (solid state devices sold either as silicon chips, or with a limited degree of packaging that allow these to be incorporated into transducers & transmitters)
The following are a few of the more significant findings of this survey.
| Product Specifications and Features Identified as Most Important in Selection of Pressure Sensing Devices (Rankings on Basis of Percent of Users Identifying Criteria) | |||
| Ranking | Process Transmitters | Non-Process Transducers/Transmitters | Component Level Sensors |
| 1 | Accuracy | Accuracy | Accuracy |
| 2 | Reliability | Reliability | Reliability |
| 3 | Durability/Ruggedness | Durability/Ruggedness | Temperature Stability |
| 4 | Ease of Calibration and Ranging | Repeatability | Repeatability |
| 5 | Repeatability | Temperature Stability | Small Size |
Other criteria identified by fewer of the users included: communication protocol, ease of maintenance, flexibility/ranging, interchangeability, linearity, response time, and weight.
Also note this table addresses only product and feature selection criteria. Non-product or "commercial" vendor selection criteria (such as price, deliver, application support, service, etc.) are treated separately in the study.
ANALYSIS BY INDUSTRIES & APPLICATIONS
The VDC reports further analyze the product selection criteria by the market segments where the products are used. The following is a summary of these findings:
- Accuracy - For process pressure transmitters, this criterion was most identified by users in the biotech/pharmaceutical, electric power, food/beverage, and water/wastewater market segments. Among the users of non-process pressure transmitters, accuracy was most identified by users for automotive vehicles, and military/aerospace applications.
- Reliability - For process pressure transmitters, reliability was identified the most by users for water/wastewater applications. Among the non-process transducer/transmitter users the highest share identifying this criteria was among those with military/aerospace applications.
- Durability/ruggedness - For the process transmitters, the largest share of users identifying this criterion were in the pulp/paper industry. The largest share for non-process transducers & transmitters was among users with automotive vehicle applications.
- Repeatability - This was most identified as a criterion among the process transmitter users for applications in the pulp/paper industry. It was cited the most among non-process pressure transducer & transmitter users for automotive vehicle applications.
- Temperature stability - Among the non-process pressure transducer & transmitter users, temperature stability was cited the most by those with automotive vehicle and military/aerospace applications.
- Ease of calibration and ranging - Again for process transmitters, this was identified the most by users with pulp/paper industry applications.
COMPONENT LEVEL SENSOR REQUIREMENTS
The criteria for the component level sensors tend to mirror the needs of the users of the transmitter and transducer products these go into. A major exception is the much greater emphasis purchasers of these products place on small size. Forty-four percent of the component level pressure sensor users identified this criterion as being one of their most important, compared to 33% of the non-process pressure transducer and transmitter users, and only 9% of the process pressure transmitter users. A much greater share of these silicon chip products go into applications where small size is important, rather than the overall shares for pressure transducer and transmitter applications.
Since these are un-packaged products, durability and ruggedness are considered less in selection than for packaged (housed) transducers and transmitters.
DIVERSITY OF REQUIREMENTS BY INDUSTRIES/APPLICATIONS
Overall, VDC found the following upon comparing the product selection criteria among users in the various industries and applications:
- Process Pressure Transmitters - The most diverse set of requirements are for the chemical/ petrochemical and oil/gas segments of the market. The least demanding in terms of breadth of requirements appear to be for food & beverage industry applications.
- Non-Process Pressure Transducers & Transmitters - The most demanding and diverse requirements are for products used in automotive vehicle and military/aerospace applications. The least demanding in terms of breadth of requirements appears to be for R&D laboratory applications.
