A rule of thumb for applying infrared temperature sensors suggests that 20% of the problem is picking the right sensor; and 80% is installing it correctly. Despite tremendous advances in sensor technologies, installing temperature sensors correctly can still be

challenging.

As the figure above illustiates.emissivity.intervening optical obstructions (smoke,steam,dust,mist,dirty window, etc.),misalignment,and reflec­tions are enough to threaten the results of any installation. Successful installation requires minimizing or eliminating the impact of these interference sources. But even the best-planned installations might not eliminate the issues that affect a sensor's readings.

The PRO Series dual- and multi-wavelength sensors feature a unique ESP technology that is used to simplify and improve the management of these troublesome applications issues. With ESP Technology the

sensor continuously monitors process conditions and automatically

responds appropriately to provide more accurate and reliable temperature measurements than traditional temperature sensors. ESP is used to:

• Simplify Installation

• Verify Sensor Performance

• Identify Error Sources

• Correct for Emissivity Irregularities

With ESP Technology, the PRO Series sensors provide a valid reading - or none at all!

Advanced ESP functions enable 'aim-and-read' capability on many applications that were previously considered difficult to measure. Some examples of applications that benefit from ESP include measurement of:

• Aluminum and other nonferrous metals

• Galvannealed Steel

• Glass Molds

• Molten Metal

• Small Wires

• Stainless Steel

• Welded Tubes
