ZRN133 Series Universal capacitive pressure transmitter is using the latest dry ceramic capacitor technology development of new products with a compact, high-performance and affordable etc. It is widely used in electric power, petrochemical, metallurgy and other industries of gas, liquid and steam pressure measurement medium, its performance is as follows:
1. Temperature drift is small, due to the cancellation of the intermediate medium. All the structure and use (sUT), (PTM) and thick film circuit technology to improve the measurement accuracy, good stability, high reliability.
2, having a cross-good chemical stability, and corrosion-resistant ceramic diaphragm can be brought into contact with a variety of chemical media, overload may reach 300% Fs and to maintain stability and zero technical characteristics.
3, with a small size and light weight and can be used directly in any installation
