transmitter和transducer有何区别? the general rule of thumb is that if the pressure sensor has a millivolt (e.g. 30mv or 100mv) or non-amplified output it is a pressure transducer. if the pressure sensor has a voltage (e.g. 0-5vdc, 0-10vdc or 1-5vdc) output it is an amplified voltage output pressure transducer. if a pressure sensor has a current loop output (e.g. 2 wire 4-20ma or 3 wire 0/4-20ma) it is a pressure transmitter. 参见下文: what is the difference between a pressure transducer and a transmitter http://www.sensorsone.co.uk/news ... -a-transmitter.html 查看更多
