Monitoring and maintaining process variables at the appropriate levels is extremely critical in

industrial auto ma tion and process control. A sensor in the industrial environment is either

continuously or periodically measuring vital parameters such as temperature, pressure, ﬂ ow,

etc. The primary challenge of sensing in industrial environments is conditioning low signal

levels in the presence of high noise and high surge voltage.

This warrants for extremely low noise, low drift, precision programmable gain ampliﬁ ers

and instrumentation ampliﬁ ers with an appropriate common-mode voltage. The rate of change

of the measured signal is usually not very rapid and hence high-resolution precision delta-

sigma converters are widely used in industrial sensors. Low power consumption is another key

requirement for industrial sensors as many of them are powered off the traditional 4–20 mA

loop. Digital connectivity features such as PROFIBUS, IO-Link, and wireless connectivity are

increasing in popularity as they provide continuous monitoring, fault diagnostics and reduce

start up times, greatly improving productivity and efﬁ ciency of the automation loop.

Texas Instruments (TI) has a broad portfolio of products catering to industrial sensing,

ranging from best-in-class precision ampliﬁ ers and data converters to interface products,

power products and high-performance microprocessors. TI’s cutting-edge semiconductor

manufacturing processes provide industrial designers with products that meet the highest

standards and that are optimized for industrial environments and extended product life cycles.
