THE PT 141 TRANSMITTER ARE USED TO SENSE DIFFERENTIAL PRESSURE ACROSS FANS, COILS, FILTERS OR BETWEEN TWO REFERENCE POINTS., THE OUTPUT SIGNAL MAY BE SENT TO A REMOTELY LOCATED RECEIVER CONTROLLER,  RECEIVER GAUGE AND/OR SENSITIVE SWITCHING PNEUMATIC RELAY AND PRESSURE SWITCH.

    THE 141 SERIES LOW DIFFERENTIAL PRESSURE TRANSMITTER IS A COMPACT, DIRECT ACTING, ONE-PIPE PNEUMATIC DEVICE THAT CONVERTS A DIFFERENTIAL PRESSURE INPUT INTO A 3 TO 15 PSIG PROPORTIONAL AIR PRESSURE SIGNAL. THE INPUT CAN BE EITHER STATIC OR VELOCITY PRESSURE DIFFERENTIALS OF A POSITIVE OR NEGATIVE TYPE., THE TRANSMITTER ARE OF THE FORCE BALANCE TYPE WITH PNEUMATIC FEEDBACK & REQUIRE AN INTERNAL RESTRICTOR IN RECEIVER CONTROLLER OR EXTERNAL RESTRICTOR IN THE SUPPLY LINE., IT MUST BE MOUNTED IN A HORIZONTAL POSITION WITH "THIS SIDE UP" ON THE TOP., IT HAS AN ATTACHED INTEGRAL MOUNTING FLANGE ON THE UNIT  WITH TWO CUT OUT HOLES FOR SCREWS.,

Low Differential Pressure Transmitter with 0 to 3″ input pressure for 1-pipe, direct acting systems to convert a differential pressure input signal into a proportional air signal. Low pressure differential transmitters operate on the force-balance principal and can be used indicate and/or control static velocity differential pressure in ducts, across fans, coils, filters and between any two reference points. The output signal can be sent to a remotely located, receiver-controller, receiver gauge and/or sensitive switching pneumatic relay and pressure switch.
