Pressure transducer principle:
LONN-1TX general pressure transducer adopts the high-accuracy and high-stability force sensitive chip with stainless steel isolation diaphragm to realize temperature and linear compensation, signal amplification, V/I switch, inverse polarity protection, and current limiting when pressure overloaded through laser resistor trimming and advanced thick-film technology. It outputs industry-standard 4-20mA or 0.5-4.5V or RS485 signal.
Field of application:
It can be used to measure the pressure, absolute pressure and negative pressure of corrosive gases, liquids and steam in the fields of petroleum, chemical industry, metallurgy, electric power and environmental protection. It can also be used to measure the pressure under low vacuum, atmospheric pressure and harsh environment.
