GSIR 6816 Series Infrared Thermometer

Transcription

1 GSIR 6816 Series Infrared Thermometer Objects having temperatures above absolute zero radiate infrared energy all the time. This infrared energy has a certain functional relations with the surface temperature of the objects. Through detector to receive this energy and by calculating to get the surface temperature is called infrared measurement. Infrared measurement has such advantages and features as quick response, high flexibility and accuracy, and also wide measurement range, especially its non contact measuring, has made measuring the temperatures of moving objects and hard to-reach location possible. Infrared thermometer consists of optical system, infrared detector, signal processing route, temperature reading and output.

2 Response time: 200ms Emissivity: 0.10~1.00 adjustable Output: 4~20mA or RS485 (Format:ASCⅡ,Baud rate:9600) Ambient temperature range: (with water cooling up to 150 ) Storage temperature : Weight: 300g Power supply: 24VDC ±10%, 100mA Analog model sensing (xxx A) operating instruction Typical application of analog model 4 lines sensing head Typical application of analog model 2 lines sensing head Analog model sensing head emissivity adjustment Set the emissivity through the two emissivity adjust switches on the panel, as the picture shows.

3 Sensor`s target aiming and fixing Press the laser switch on the panel, and the switch in on. Use the co axial laser to aim at the target, and then fix the mounting bracket, 10s later, the laser will be off automatically. The following three types use laser to aim at the target. First, press the power button(a) to turn it on, and move the laser aimer up in front of the sensor. Then use laser to aim at the target, fix the mounting bracket, move the laser aimer down and press the button to turn it off. When laser is power off or weak, replace the battery. Remove the back cover (b) down, replace the battery (c), then put the cover on. Pay attention to the polarity, the type of the battery is CR1220.

4 Caution Sensor to object The farthest distance between the sensing head and the object is decided by the size of the object and the location of the sensing head. Distance ratio refers to the object`s location L and optical target`s diameter d. the bigger the distance ratio K=L/d, the smaller the size of the object can be in the same distance situation, or the distance can be farther for the same size objects. In order to get an ideal effect, the actual size of the object is bigger than the size calculated by the distance ratio, at least 1.5 times to the value. Emissivity Materials have different emissivity due to its different situation of the surface. People design an ideal object blackbody when studying the infrared radiation. It s an object of which absorption rate of incoming infrared energy equals under any circumstances. In order to compensate the measuring difference due to different emissivity, conditioning the emissivity value based on materials should be done. (appendix 1 lists some emissive value of parts of the materials) Environment temperature Great changes in the environment temperature will lower the accuracy of the sensor, but it will be normal after a minutes. The working temperature range of the sensor is 18 ~50. When the temperature is above 50, water cooling house should be used. When use it, the temperature can be up to 150. Air quality An ordinary air medium is permitted to exist between the sensor and the object, but if there are larger quantity of vapor, powder smoke, it will affect the accuracy, so air sweeper and water cooling house are suggested to be use to lessen the difference and avoid destroying the lens. Ele magnetic interference In order to reduce the interference, please pay attention to the following: The sensor should be away from the strong powder and magnet supply. Make sure the sensor is completely insulated. Make sure the sensor is connected to the cable.

5 Laser safety Laser is harmful to human eyes, do not point to human eyes when using.

6 Fixed mounting bracket Connection of cables Move anticlockwise the back cover of the sensor, release the waterproof locker, put the cable through the locker and connect it according to the definition of the terminal. Move the back cover on and screw the locker. The terminal of GSIR and VTIR

7 Maintenance Lens cleaning Blow off particles by using clean compressed air. Gently brush the remaining debris away with a camel`s hair brush. Carefully wipe the surface with a moist cotton swab or clean soft rag. The swab or rag may be moistened with water based glass cleaner. Case cleaning To clean the exterior housing, simply use soap and water or a mild commercial cleaner. Wipe with soft rag. Warranty Our products are warranted for one year on the condition of normal use and maintenance. We offer lifelong fee based service when the products are over warranty period.
