Why Use The IRt/c™?

Temperature is one of the most commonly measured and controlled parameters in industry
That statement alone should provide a clue as to why you want to utilize IRt/c’s.

Proper monitoring and control of process temperature improves product quality, reduces product scrap, and improves overall product yield and process speed.

Every industry in today’s competitive marketplace is putting in place programs and systems to lower production costs, through automated production and quality control systems. The benefits of employing Exergen Infrared Temperature products contribute directly to the bottom line.

Exergen products are easy to use
Exergen temperature sensors provide a cost effective means for obtaining highly accurate and reliable temperature data. These products provide you a powerful new technology. Designed to emulate a thermocouple signal, these sensors will replace any existing in-line thermocouple measurement.

Providing a direct measurement of product temperature, not thermocouple temperature, results in faster and more accurate results.

The sensor’s small size and rugged construction make integration into systems simple. Plus, these sensors are factory calibrated and require no power for operation, further simplifying installation.

For linearity and permanent, drift free accuracy over a wide temperature range, and a non thermocouple signal output (i.e. 0-5V, 0-10V, 4-20mA, or RS-232), the Plug and Play Smart IRt/c is available. No thermocouple knowledge is necessary (cold junction compensation, t/c cable, leakage current, impedance, etc.).

Similarly, the D Series and DX Series are an entirely different type of instrument than conventional temperature measuring devices. Designed specifically for the highest possible accuracy, they are the only instruments that can be certified with NIST-traceable accuracy on real surfaces of unknown emissivity, while remaining completely free of the contact errors and heat sinking errors of contact devices.

What is Infrared Thermometry?

This measuring technique uses the properties of IR light waves to determine a target’s temperature. By employing an infrared detector, the sensor detects the amount of thermal energy emitted from a target as IR light. There is a known relationship between the amount of infrared radiation emitted by an object and the object’s surface temperature. Exergen products detect only specific IR wavelengths, so other sources of IR light, such as the sun, will not interfere with the measurement. Exergen can calibrate the IRt/c™ to provide a linear output signal similar to a specific thermocouple type, over a specified temperature range.

How infrared temperature technology improves your process control and throughput

• Increase production speed (see Speed Boost Equation, www.exergen.com/industrl/spdboost)
• Reduce scrap costs through regulation of process critical procedures
• Improve quality with a low cost, direct monitoring solution
• Decrease safety risks due to out of control processes
• Measure moving or dirty samples, too difficult or labor intensive for a contact measurement technique

Why use Infrared Temperature Technology, over other measurement techniques?

• Non destructive measurement method, so no damage to the product
• Non contact method means less cleaning and maintenance required
• No breakage due to contact with moving objects
• Fast thermal response time
• Wide temperature range
• Highly accurate data, by measuring actual product temperature, not the sensor’s temperature
