KEYENCE FT-55A Digital infrared temperature sensor (amplifier unit)

Core Features

• ✓  Non-contact temperature measurement: Utilizing advanced infrared technology, it accurately measures the surface temperature of objects, making it particularly suitable for high-temperature or inaccessible industrial environments.
• ✓  Adaptive emissivity: Equipped with adaptive emissivity functionality, users no longer need to manually set the emissivity of the object being measured. Simply input the current temperature, and the device automatically calculates and provides an accurate reading, greatly simplifying the operation process.
• ✓  Fast response and multiple memory banks: Extremely fast response speed (up to 15ms) and supports switching between up to 4 memory banks, each with individually set emissivity and limit values, adapting to rapid switching detection of various materials.
• ✓  Intuitive dual-color display: Equipped with a 7-segment LED dual-color display (red/green) with 4 digits and 2 digits, character heights of 8mm and 5.7mm respectively, and a display update cycle of 10 times/second, providing clear and intuitive readings.

Q: In what scenarios is this product primarily used?

A: The FT-55A is typically used in any industrial production process involving high temperatures, moving objects, small targets, or where temperature detection needs to avoid contact with contaminants.

Q: What sensor head models are available?

A: The FT-55A amplifier can be paired with a variety of infrared sensor heads of different specifications to meet diverse measurement needs, from small targets to ultra-long distances and ultra-high temperatures. The main available sensor head models include: FT-H10, FT-H20, FT-H30, FT-H50, FT-H40K, and FT-H50K.

The display resolution of the FT-55A will vary depending on the sensor head selected. When used with H10, H20, and H30, the resolution can reach 0.1°C; while when used with H50, H40K, and H50K, the resolution is 1°C. You can choose the most suitable sensor head model based on the actual size of the target being measured, the distance, and the temperature range.

Q: How do I wire its 4-20mA analog output?

A: The FT-55A's 4-20mA analog output uses a standard two-wire loop power supply. When wiring, the sensor, external DC power supply, and receiving device (such as a PLC, temperature controller, or ammeter) need to be connected in series in the same closed loop.
