Hello Dear first check the Calibration Range of Transmitter,
Range should be -xxx(495) to 0 mmwc. for 0 mmwc 20 mA will
be come.when you fill the water in condensate pot 4mA wii
be come because it's closed vessels

Answer / ashish mahadik

U have to apply WET LEg method for Differental Pressure
type level mesurmetnt.Keep ur wet leg(Lo side of tx always
filled with condensed water.
Put the range in tx.-19.5 inches of WC to 0 inches of WC.
see the result but make sure that ur wet leg should always
filled with water.otherwise ur tx l go to saturation and
give u contunous 20 mamp that is level is full.

you must show the examples application and give at least 4 types of transducer/sensors that can minimize the failure during the manufacturing of the resistors.
