Tips: Why the pressure transducer output signal is smaller than 4mA?
When the differential pressure transducer and orifice plate cooperate to measure flow rate, blockage or severe leakage of high pressure connecting pipe in differential pressure transducer makes the pressure in negative pressure chamber higher than that of positive pressure chamber, the output current of pressure transducer is smaller than 4mA. The output of the differential pressure transducer can return normal through the drainage, dredging the connecting pies or sealing the leakage points. Reverse connection of the differential pressure transducer's high pressure and low pressure connecting pipes will make the output current smaller than 4mA, and smart pressure transducer can solve this problem only by selecting reverse output in parameter configuration.
Pressure transducer with classic 2088 type head can be used in humid or harsh environment for a long time. Pressure transducer has optional measuring range -0.1~60MPa/ -1~600bar/ -14~8702psi, medium temperature -40~+60℃ (-40~+140℉), special for air/water/oil pressure measurement. The internal ASICs convert the mV signal into a standard current (4-20mA/0-20mA), voltage (0-5V/1-5V/0-10V) or RS485 signal.
