The integration of thermocouple temperature sensor protection tube should pay attention to the problem1

Site integration overview shows thermocouple

the integration display thermocouple temperature measuring meter is a new type of structure, the LCD or LED digital display, temperature transmitter second-line 4 ~ 20 madc signal output, temperature sensing element can be used armoured pressure reed aseismatic structure, temperature sensing element and the protection tube adopts cylinder flame-proof structure, has the characteristics of the core pulling. Applicable to petroleum, chemical industry, light industry, electric power industries, medium such as air, steam, the mist containing hydrocarbon and places of explosive mixture and corrosiveness, measurement range - 200 ~ 1000 ℃, the scene show particularly applicable to cannot use bimetallic thermometer measurement of high temperature medium, etc.

the integrated display thermocouple technology parameter

output signals: 4 ~ 20 madc or 1 ~ 5 VDC, 250 Ω load resistance.

power supply voltage: 24 VDC plus or minus 10%

: insulation resistance meter output terminal and the shell of the insulation resistance between should be 50 m or more Ω

basic error: instrument basic error should be no more than the thermal resistance ( I) Basic error tolerance and temperature transmitter limit composite error of two parts.

explosion-proof marks: d Ⅱ BT4, d Ⅱ CT4

protection grade: IP65

the integrated display thermocouple installation information

1, the series of products should be horizontal or vertical installation, in order to avoid the tilt error value.

2 indicating meter shell surface is the highest temperature should not exceed the highest temperature environment, in case of high temperature, the manufacturing can be extended protection tube; Junction box should not contact with the walls of the measured medium, and should avoid strong vibration.

3 with thermal resistance, thermocouple temperature modulator, installation should be no radio frequency interference.

4 for horizontal installation forms of product, when installation should loosen the union first, after waiting for instrument installation in place, then tighten the union.

5 links to correct and reliable, to balance the environment temperature.

6 external terminals must be reliable grounding, grounding resistance of 10 or less Ω, remove, should first disconnect the power supply.

the integrated display thermocouple applicable ambient conditions

1 ambient air pressure from 86 to 106 kpa, environment temperature - 40 ~ 80 ℃, relative humidity 5 ~ 95%.

2 products are suitable for the environment of combustible gas or flammable gas explosion rank no higher than Ⅱ class B or C group, spontaneous combustion temperature is not lower than the T4 ( 135℃) Level, Ⅰ area or Ⅱ area dangerous gas.
