Product Description
The W330 portable thermocouple indicator is connected with the thermocouple used for monitoring the temperature of molten metal for melting and casting.
This instrument by the high performance of a single-chip computer as the core, the high precision accuracy measuring transducer parts, and take multiple intelligent processing technology, to ensure the long-term stability instrument. Improve the anti-interference ability of the instrument.
Matching 5 type thermocouple.
Main Features
1.Automatic save measuring temperature records
2.Acousto-optic to suggest you the measuring over.(When you hold the lance)
3. It has the function of fault alarm for power line broken,bad connect and overrange .
4.Power adopt nickel metal hydride rechargeable batteries( One charging time,the Lance can used 1000 times )
5.Automatic two minutes after the power input signal no
6.Strong anti-jamming ability
Technical performance target
1Measurement range and accuracy of measurement
2.resolution (℃):1
3response time(S):1
4environmental condition
(1)working condition: Temperature(℃):0-50; Humidity(%RH):5-80
(2)storage condition:Temperature(℃)-20-60; Humidity(%RH):5-90
5Power: DC6V±10%(rechargeable Ni/MH battery)
Working principle
W330 type indicator is a sensor to connect with sensor.
Thermocouple temperature measurement is generated when the electric potential after instrument preamplifier device, and then after A/D converter converted into digital quantity, let into the data processing in the computer, and realize the environment temperature automatic compensation, zero since calibration, furnace temperature stable value is automatically and keep.
This instrument is over, when measured with a light, sound synchronous tip measurement buzzer is over, display temperature measurement, and keep a value measurement for a time.
Install or operate
1.Install
A The indicator
B Screw
C The Lance
D The Thermocouple plug
E The plug in the socket must put it to the end
3. Choose instrument dividing number
Thermocouple type of change method
Shut down power, carefully opened instrument instrument shell (note data line direction, sealing machine the same sealing back) Moving within four switch instruments.
Precautions
1 Temperature measurement, don't make thermocouple touch a charged object, in order to prevent the damage the instrument or disturbance error.
2. This instrument for precision instrument, do not put the instrument down and temperature sensor in the fall on the ground benaiah, so as not to measuring temperature of the water vapor into the instrument in stuck inside, thus corroded, instrument.
A: On the wall for two nails, the instrument in a horizontal position on a nail
3.Measuring the same configuration requires thermocouple type
4.When the indicator not display “help”,don`t charge the battery. Often charge will affect battery life.
5.when the indicator display”help”,mean Voltage that lack,the battery must be charged.
Before charging, must close instrument, loosen the instrument with the power supply at the bottom of the "charge mouth," the words of the cap, Covering plate gap along the direction gently slid open cover piece, make show charging hole, insert the charger can charge.
The charger, the indicator light show charging red, rechargeable batteries, charger lights full display green. General charging four hours.
Temperature measurement lance in high temperature in metallic solution should be more than 7 seconds, cloth will be burning thermocouple connector.
Calibrate:
General instruments, such as to work, they can maintain measuring precision. If a user has special requirements should be calibrated the instrument, can be sent to the technical supervision department or posted back to the company calibration.
The conditions, in accordance with the calibration method as follow:
According to the thermocouple give thermoelectric emfs(attached list)subtract The ambient temperature of the corresponding electromotive force(B type instrument Without temperature compensation),then, Will the difference with magnitude 0.05 standard dc potential difference to input the instrument project.
Eg: In the environmental temperature 20 degrees Celsius, under the condition of proofreading S type of instruments in the accuracy of 1700 degrees Celsius, the procedure is as follows:
The first:found in file S type in 20 ℃ electromotive force is 0.113mv,1700℃ is 17.947mv
17.947-0.113=17.834 input the instrment,then results observation, If beyond error range, shown in the position adjust potentiometer R16, to display temperature digital into the normal range, can use sealing machine.
