KH181 Universal Pressure Transmitter
Introduction
KH181 universal pressure transmitter adopts imported advanced sensitiveλ components with high-precision and high stability and changes ×AP or GP of the measured object into 4 ~ 20mA or 0 ~ 5V standard signal through high reliable a&mplifier circuit and accurate temperature compensation. The transducer can achieve automatic εmeasurement and controlling by the high-quality sensors, exquisite packaging, perfect♦ assembling technology, industrial computer and distributed system interf÷ace. It can be widely used in petroleum, metallurgy, chemica•l industry, electric power, light industry, mechanical and environmental protection and o∑ther fields
