AVT5108 B

Displaying the temperature from several sensors requires a transparent way to identify a given measurement channel. When using alphanumeric displays, this is not a problem - the displayed value can be supplemented with an appropriate description. The problem arises if we want to use typical 7-segment LED displays. The most common way to identify the sensor being read is to use additional LEDs. Such a system, however simple, has one disadvantage - reading from a greater distance can be troublesome.
The presented putty uses the original way of indicating which of the two sensors is currently being sensed. This is evidenced by the color in which the measured value is displayed. This is possible due to the use of special, two-color, seven-segment LED indicators.

The device is especially recommended wherever a two-point temperature measurement is needed

Selected parameters:

• two measuring channels
• imaging results - a four-figure, two-color LED display
• identification of the measuring channel with lighting color (red / green)
• choice of manual or automatic channel
• measuring range -55 - +99,9 stC
• resolution 0.1 stC
• programmable time of activity of each channel
• tile dimensions 86x36mm
• power supply - 9-12Vdc
• in the set, printed circuit boards, programmed layout, set of elements and documentation
  An assembled version of AVT5108 C is available
