Page 30: Ambient Temperature Compensation
Operation 4.5.3 Ambient Temperature Compensation The sensor is capable of improving the accuracy of target temperature measurements by taking into account the ambient or background temperature. This feature is useful when the target emissivity is below 1.0 and the background temperature is significantly hotter than the target temperature. For instance, the higher temperature of a furnace wall could lead to hotter temperatures being measured especially for low emissivity targets. -

External switch: - Relay contacts, - Transistor, - TTL output, … Figure 24: Wiring the FTC3 Input Trigger: A logical low signal at the input FTC3 will reset the peak or valley hold function. As long as the input is kept at logical low level, the software will transfer the actual object temperatures toward the output. -

Accessories 5.2 Adjustable Bracket Figure 30: Adjustable Bracket (XXXTXXACAB) 5.3 Air Purge Collar The Air Purge Collar (XXXTXXACAP) is used to keep dust, moisture, airborne particles, and vapors away from the lens. It can be mounted before or after the bracket. The airflow is passed through 1/8” NPT stainless steel fitting onto the front aperture. -
Page 38: Sighting Viewer
Accessories Figure 32: Right Angle Mirror When using the Right Angle Mirror, adjust the emissivity settings downward by 5%. For example, for an object with an emissivity of 0.65, you adjust the value down to 0.62. This correction accounts for energy losses in the mirror. 5.5 Sighting Viewer The Sighting Viewer (XXXTXXACSV) is used to aid in the alignment of the standard sensor. -
Page 39: Protective Window
Accessories 5.7 Protective Window Protective windows can be used to protect the sensor’s optic against dust and other contaminations. For sensors with plastic lenses the use of a protective window combined with the air purge is strongly recommended. The following table provides an overview of the available protective windows. All protective windows have a transmission below 100%. -
Page 40: Air/Water-Cooled Housing
Accessories 5.8 Air/Water-Cooled Housing The Air/Water-Cooled Housing accessory allows the sensor to be used in ambient temperatures up to 120°C (250°F) with air-cooling, and 180°C (356°F) with water-cooling. The cooling media should be connected using 1/8” NPT fittings. Air flow should be 1.4 to 2.5 l/sec at 25°C (77°F). Water flow should be approximately 1.0 to 2.0 l/min (water temperature between 10 and 27°C (50 to 80.6°F). -
Page 41: Avoidance Of Condensation
Accessories 5.8.2 Avoidance of Condensation If environmental condition makes water cooling necessary, it is strictly recommended to check whether condensation will be a real problem or not. Water cooling also causes a cooling of the air in the inner part of the device. Thereby the capability of the air to store water decreases. -
