Application of pressure transmitter LED-13 series
Its performance is as follows:
1. The temperature drift is small, and due to the elimination of the intermediate medium, the national structure adopts (SUT), (PTM), and thick film electrical technology, which improves measurement accuracy, stability, and reliability.
2. Has good chemical stability, can overload up to 150% Fs, and can maintain zero point and technical stability.
3. It has a small volume, light weight, and can be directly and arbitrarily installed on pipelines. It can be selected from multiple ranges and adjusted to 1:5 range.
4. Compared to other similar products, it hasgoodThe performance price ratio.
