No. SS2-GTX00R-0100 Azbil Corporation - 10 - E. Temperature characteristics of capillary tube An integrated shift is shown, when temperatures difference is generated between the upper flange side capillary tube and the lower range capillary tube by the influence of the radiant heat and the sun light in the process. Note) Take into account the shift when the transmitter is in the following conditions. - One side of the capirally tube is in the sun and the other side of the capirally tube is in the shade. - Radiant heat in the process hits one side of the capirally tube. When a temperature difference is large between the upper flange side capirally tube and the lower flange side capirally tube, take the following typical measures against the diferences. - Arrangement of the capirally tubes - Use of moistunizing material - Use of shielding plates against the radiant heat χ : Shown for each item are the percentage ratio for χ (kPa), which is the greatest value of either the upper range value (URV)*1, the lower range value (LRV)*2 or the span. L : Length of capillary tube with temperature difference. ΔΤ : Temperature difference between upper flange and lower flange. *1: URV denotes the process value for 100% (20 mA DC) output. *2: LRV denotes the process value for 0% (4 mA DC) output.
