1. Product introduction

TD500 series large-screen temperature display is a kind of intelligent temperature display, which is a display supporting instrument for infrared pyrometer or other detector instruments. Using dot matrix red LED scanning display, compared with ordinary methods, power consumption is lower. The displayed pixels are accurate to each pixel, and even individual damage will not affect the entire display. It can be hung on the wall, clearly visible within 50 meters, and the display is intuitive and convenient.

It can arbitrarily modify the range setting of the instrument, and the signal processing functions include peak value, valley value, and average value. And according to user needs, the average temperature within a period of time can be retained, and it will be automatically updated when the next temperature arrives. With instrument self-check function and accuracy correction function.

2. Technical parameters

Working power supply	AC220(1±20%)V, with EMI filter
Input signal	4mA～20mA, sampling resistance 100 ohm, with overvoltage protection, overcurrent protection
Measurement accuracy	±0.2%tm℃(tm is the upper limit of temperature measurement range)
Repeat accuracy	±1℃
Response time	10ms
The upper limit corresponds to the temperature	Setting range is -50℃～3200℃, the upper limit temperature corresponds to 20mA
The lower limit corresponds to the temperature	Setting range is -50℃～3200℃, the lower limit temperature corresponds to 4mA
Measurement mode	Real-time temperature: setting time is 0.0s, response time is 10ms
	Peak temperature: Set time from 0s to 99.9s, >99.0s is infinite hold.
	Valley temperature: Set time from 0s to 99.9s, >99.0s is infinite hold.
	Average temperature: setting time 0s～60.0s, average response time For the time it takes for the signal to rise to 95%, a first-order RC algorithm is used.
Correction coefficient	Setting range is 990～1010, and the coefficient is 1000 without calibration
Average Trigger function	User can choose to turn it on or off, and you can set the upper limit and lower limit of the trigger temperature. The upper limit temperature and the lower limit temperature of the trigger, the setting range is -50℃～3000℃. Automatically maintain the average temperature of the previous target.
Display self-calibration function	Display “88.88℃”, used for LED light-emitting tube test.
Power-down protection function	When the power is off, the values of various parameters set will be retained
Alarm function	User can set the upper and lower limit alarm threshold . And there is corresponding relay output, node capacity 5A/250VAC
Using environment	Ambient temperature: -10℃～60℃, relative humidity: 10～95%, no condensation
Power consumption	Without alarm: 6W (all LEDs on) With alarm: 16W (LEDs are all on and the alarm is activated at the same time), the alarm is optional
Dimensions	Length, width and height (500mm168mm65mm)
