Temp control selection commercial, not technical
A recent study conducted by VDC Research Group indicates
that the global market for the industrial electronic temperature controllers
under the study is forecast to decline at a 0.7% per year rate through 2013.
The study, titled “Industrial Electronic Temperature Controllers: Global Market
Demand Analysis, Tenth Edition” surveyed users, OEMs and system integrators to
understand selection trends for microprocessor-based, single-loop, industrial
electronic temperature controllers.
According to the report, the Asia-Pacific region accounted
for the largest 2008 market share, followed by EMEA and then the Americas. The
EMEA and Americas
markets are forecast to decline over the next five years. The Asia-Pacific
market is forecast to grow through 2013.
The report said that microprocessor-based, single-loop
controllers accounted for a high majority of the 2008 market;
microprocessor-based, multi-loop controllers accounted for most of the balance;
with small numbers for hybrid and analog type controllers. Analog controllers
are forecast to have the sharpest shipment decline, followed by multi-loop,
with a much smaller decline for hybrid and single-loop controllers. Analog
types are being displaced by more flexible microprocessor-based types, and
these (particularly microprocessor-based, multi-loop types) are being displaced
by PLCs, PCs and DCSs. Unit shipment increases are expected for each product
type except analog.
The VDC report also said that the trend is from manual
control to temperature controllers, and onto control loop implementations in
higher-level multi-functional machine, and process controllers using PLCs, PCs
and DCSs. Hybrid controllers, introduced to counter the PLC, PC and DCS threat,
have gained a small market share, but shipments of these are now forecast to
slowly decline as well.
Although there is no single overriding factor cited by users
when selecting industrial temperature controllers, a recent study conducted by
VDC Research Group indicates the most identified selection criteria include
reliability, ease of use, accuracy, PID control and quality.
Users were also asked about their most important non-product
or “commercial” criteria in selecting industrial electronic temperature
controller suppliers. The top five most identified non-product selection
- Application assistance
- Ease of working with vendor.
“Suppliers of industrial electronic temperature controllers
are undergoing an increase in competition from alternative means of control loop
implementations such as PLCs, PCs and DCSs,” said Robert Torres, an analyst at
VDC. “Thus, VDC suppliers need to focus on capturing market share by investing
in meeting the selection criteria of users.
“It is important to note that nearly all of the most popular
criteria used to select vendors and products are also among the problems most
cited by users,” Torres said. “Vendors should concentrate on offering reliable,
low-cost products with good performance that are easy to use and simple and
straightforward to order, receive, install and maintain. Providing high-quality
products, timely delivery, good documentation and good service and support will
help provide market differentiation from other vendors that do not work closely
with customers to satisfy their needs.”
