Description

FT Series digital infrared temperature sensors are designed to provide wide temperature detecting ranges, high responsiveness, long detecting distances, and easy installation and settings. The thickness of the far-infrared resonance film of the thermopile (array of thermocouples) used for temperature detection is reduced as much as possible to allow efficient thermocouple arrangement. This makes quick and reliable detection of absorbed heat possible and improves the response speed of the thermopile. The lineup is available in two types: high temperature models and mid to low temperature models. Since the detection area can be checked visually with a visible laser beam, it is easy to align the sensor position during installation. The current temperature of the target can be input directly on the amplifier unit. This eliminates the work needed to set emissivity for each target. Obvious Detection Range with Visible Laser Pointers The FT Series is equipped with two laser pointers* that clearly indicate the detection range, simplifying installation. Varied Lineup with Detection at Distances of up to 3000mm Depending on the application, an increased distance between the target and the sensor may be necessary. With several sensor head options available - from small beam spot to long range—the FT Series can be used in a wide variety of installation environments. Usable In Harsh Conditions with a Resistant Air Purge Box Made of zinc die-casting, this robust box offers air purge functionality to meet elevated environmental resistance requirements such as in areas prone to steam, smoke, dust, oil mist, or high temperatures.
