MOQ: Not Specified
 
Product Introduction
SF6 switch is a widely used high voltage electrical appliance in the power system. SF6 gas density relay is an important element used to monitor the variation of SF6 gas density in the SF6 switch body during operation. Its performance directly affects the operation safety of SF6 switch.Due to the infrequent operation of SF6 gas density relay in the field it is often found that the operation is not flexible and the contact contact is not good after a period of time and some of the temperature compensation performance of the density relay becomes worse. When the ambient temperature changes suddenly the SF6 density relay often misoperates.Therefore DL/T596-2005 "precautionary test regulations for power equipment" stipulates that each SF6 switch user should verify SF6 gas density relay regularly.From the perspective of actual operation it is necessary to carry out regular calibration of SF6 density relay and pressure gauge in field operation.

The check pressure sensor with high precision and high speed A/D converter combining with the 32 bit high performance microprocessor can check the performance of A variety of SF6 gas density relay can accurately measure the movement of the signal when the current temperature pressure value arbitrary automatically when the environment temperature of 20 â?? conversion standard pressure and have A print store and U disk offload function at the same time the fault in the process of automatic identification test.Sf6 gas density relay calibrator is convenient to carry simple to operate high test accuracy strong stability and good reliability which reflects the characteristics of "intelligent" instrument.

Guar gum is a fiber from the seed of the guar plant.
Guar gum is used as a laxative. It is also used for treating diarrhea, irritable bowel syndrome (IBS), obesity, and diabetes; for reducing cholesterol; and for preventing “hardening of the arteries” (atherosclerosis).
In foods and beverages, guar gum is used as a thickening, stabilizing, suspending, and binding agent.
In manufacturing, guar gum is used as a binding agent in tablets, and as a thickening agent in lotions and creams.
How does it work?
Guar gum is a fiber that normalizes the moisture content of the stool, absorbing excess liquid in diarrhea, and softening the stool in constipation. It also might help decrease the amount of cholesterol and glucose that is absorbed in the stomach and intestines.
There is some interest in using guar gum for weight loss because it expands in the intestine, causing a sense of fullness. This may decrease appetite.
USES:
Diarrhea. Adding guar gum to the tube feeding formula given to critical care patients may shorten episodes of diarrhea from about 30 days to about 8 days.
High cholesterol. Taking guar gum seems to lower cholesterol levels in people with high cholesterol. Guar gum and pectin, taken with small amounts of insoluble fiber, also lower total and “bad” low-density lipoprotein (LDL) cholesterol, but don't affect “good” high-density lipoprotein (HDL) cholesterol or other blood fats called triglycerides.
Diabetes. Taking guar gum with meals seems to lower blood sugar after meals in people with diabetes. By slowing stomach emptying, guar gum may also lessen after-meal drops in blood pressure that occur frequently in people with diabetes.
Constipation.
Irritable bowel syndrome (IBS).
