Door thermometer non-contact measurement, non-contact with human body, avoid cross infection, and do not need sanitation and disinfection

  Portal thermometer cw110a  This door type thermometer is composed of infrared optical lens, filter, sensor and electrical signal processing unit
It can detect the infrared radiation from the measured target, and determine the temperature of the target according to its radiation intensity
It can be easily installed in a variety of applications, especially suitable for installation in industrial environments that require long-distance and strong interference
The door type infrared thermometer adopts a cast aluminum shell, which has good protection ability at the temperature measurement site
Door thermometer cw110a Product Description: this instrument measures the surface temperature of human forehead, and then obtains the actual body temperature according to the relationship between the temperature of human forehead and body temperature
The optical component of the detector collects the energy emitted and reflected by the forehead onto the sensor, and converts this information into a temperature reading through the electronic component and displays it on the display panel
When the temperature reading exceeds the high temperature alarm value, the instrument will send out an alarm sound, and the red alarm light will be on at the same time
If the body temperature is normal, the green alarm light will be on Cw110a main technical parameters: technical specifications temperature measurement range   0-50 (℃) response time   & lt; 150 (MS) temperature resolution   0

It is convenient to screen patients with fever symptoms to reduce infection and epidemic spread Working principle: (1) all objects with a temperature higher than Jue to zero in nature are constantly radiating electromagnetic waves, including infrared bands, into the surrounding space due to the thermal motion of molecules, and their radiation energy density is directly proportional to the fourth power of the temperature of the object itself
Small temperature changes will cause obvious changes in radiation energy, so the sensitivity of using infrared radiation to measure the temperature of objects is very high
(2) The infrared radiation characteristics of human body are closely related to its surface temperature
The main radiation wavelength of human body is 9~10 μ M infrared, through the measurement of the infrared energy radiated by the human body itself, the surface temperature of the human body can be accurately measured
Because the light within this wavelength range is not absorbed by the air, the infrared energy radiated by the human body can be used to accurately measure the surface temperature of the human body
(3) The biggest advantage of infrared temperature measurement technology is non-contact, fast measurement, and the test can be completed within 1 second
Since the infrared thermometer only receives the infrared radiation energy emitted by the human body, there is no other physical and chemical factors acting on the human body, so it is not harmful to the human body Use characteristics of infrared thermometer: non-contact measurement, non-contact with human body, avoid cross infection, and do not need sanitation and disinfection
The detection speed is fast, generally less than 0
5 seconds
The body surface temperature is automatically converted, and the measured results of the forehead surface temperature are converted into the underarm temperature of the human body and then displayed
The body temperature exceeds 38 DEG; The display will alarm automatically, the red light of the detector will flash, and a beep will be sent to remind the inspectors
The alarm temperature is set by itself, such as 37
8° C。 The ambient temperature is automatically compensated to eliminate the measurement error caused by the change of ambient temperature
The output cable can use twisted pair with * layer or multiple groups of twisted pairs
Requirements for conductor sectional area (copper): 0
2mm2 sectional area when it is up to 250m; 0
5mm2 sectional area when it is up to 650m   The installation distance and measurement size cw110a optical resolution is 50:1, and the corresponding measurement field of view can be approximately calculated with reference to the attached optical path diagram
In order to improve the measurement accuracy, it is necessary to ensure that the size of the measured object is larger than the measurement field of view, especially when the object or thermometer is shaking
Cleaning of measurement channel and lens: ensure the cleanness of measurement channel
Dust and smoke will affect the transmission of radiant energy and reduce the measurement accuracy
The optical lens of the thermometer must be kept clean to avoid measurement errors or even damage to the lens due to dust, soot and other pollutants
If the lens is stuck with dust
Wipe with a clean cotton swab or lens paper dipped in absolute alcohol
Alarm value adjustment: 1 Long press the set key of the display instrument, when ah appears, press the ＜ enter key to set the alarm value, and long press the set key to return after setting
Temperature correction: long press the set key When ah appears, press set key to find OA, press ＜ enter key to enter 1111, long press set key to appear inch, and then press ∧ Key or ∨ Key to find in-a, press the ＜ enter key to correct the zero point, set the temperature for correction, and then press and hold the set key to return Electromagnetic interference: in order to prevent electromagnetic interference, try to keep the infrared thermometer away from the electromagnetic field source (such as motor, motor, high-power cable, etc
) during installation
If necessary, add metal sleeve to improve the effect
