The FT-50AW(P) and FT-55AW(P) come with functions that can be used on-site, eliminating complexity and difficulty.
In the past, the correct temperature was displayed only when the emissivity that matched the material of the detection object was set correctly. For the FT Series, the user only has to enter the current temperature of the detection object. This is because the FT Series automatically calculates the emissivity from the entered current temperature. The user doesn't have to worry about complex emissivity calculations.
1. Enter the surface temperature directly.
2. Pressing the“SET”button calculates and sets the optimum emissivity automatically.
If two different materials have the same temperature, the quantity of far-infrared rays being emitted by each differs. This results in different emissivity values that are used to calculate temperature. Emissivity is based on a scale from 0 to 1 of the quantity of far-infrared rays being emitted from that material.
Water: 0.92 to 0.96
Plastic: 0.85 to 0.95
Stainless steel: 0.45
Ceramic: 0.90 to 0.94
The FT-50AW (P) and FT-55AW (P) provide analog monitor outputs (4 mA to 20 mA) corresponding to the displayed values.
Setting the upper and lower limit values provides simple scaling.
The FT-50AW (P) and FT-55AW (P) can each store two upper-limit outputs and two lower-limit outputs. They can also be configured for up to 4 emissivities. This eliminates the need to reset emissivities for each product changeover.
In the past, (amplifiers before the FT-50AW (P) and FT-55AW (P)), it was difficult to confirm the surface temperature of workpieces moving at high speed. The Display Hold function enables the user to confirm the surface temperature of moving workpieces at their own speed since it can store and display the instantaneous maximum temperature.
The Timing function only displays the upper and lower temperatures when the timing input is on. This prevents unnecessary temperature readings like that of the conveyor or background oven regardless of where they fall with respect to the upper and lower temperature settings.
The IR mode displays the quantity of far-infrared rays received by
the thermopile so that it acts like an intensity sensor. Because
this, the FT-50AW (P) and FT-55AW (P) could be used just like a photoeye to detect presence or absense of hot materials.
The Power Saving function provides a simplified display when the sensor is left alone for a fixed time.
* If the Analogue Monitor Output function or the Timing function is
used, up to two banks can be used.
If both functions are used, only one bank can be used.
