1. Profiles:

HPT903 series digital-intellectual pressuretransmitter is a high - accuracy digital and intellectual product developed by German HELM to meet the market needs of Chinese mainland. This series of product adopt German HELM made sensor chip with highest performance and are designed incorporating with monolithic computer technology and sensor digital conversion technology, of which core component adopts 24-bit AD MCU micro – processor to ensure high quality of the transducer relying on its strong function and high - speed operation capacity. The overall designed framework is to meet the requirements of increasingly enhanced industrial site application with a view to reliability, stability, high accuracy, and the product also features strong function and without manually operating device to ensure good interaction. Application digital signal processing technology is made for good disturbance immunity. It also features zero point automatic stable follow - up capacity and temperature automatic compensation capacity.
