Differential pressure transmitter response -- "high" and "low" ports

This video demonstrates the different responses of a "dp cell" differential pressure transmitter to both positive and negative pressures applied to its ports. The response of pressure and vacuum to the "high" port is opposite the effect of pressure and vacuum (respectively) applied to the "low" port.

Did you blow on the hose?

[@pinknoized9898]

can you give me the brand name and model of your dp transmitter and where i can buy thank you

[@shamshiqubal348]

sir u said 4 1000 ohm resitance paralleledconennected to form 250 ohm resistance

[@izountarcharafeddine226]

hi mr i have a problem in my mvt ,the dp it's giving -67.7 mbar without flowing please i want to contact you. to give you more explanation.

[@danish1794]

nice sir ,good lecture ,would you like to demostrate how this Pt is calibrate .......thanks

[@Swapsakshi_technical]

nice video sir can i interchange the tappings if my tank is in vaccum..? will i get perfect reading ?

Go to google, seach for "socratic instrumentation". There you will find an online textbook as well as worksheets used to teach this subject to students at Bellingham Technical College.

How to make transmeter diffrention pressure appear display the unity m ^ 3 / h

[@hdmech4625]

a lot of thanks ..

[@fahmyfaishal5246]

thats awesome!!

[@TiberiusStorm]

How do you apply a vacuum to the Transmitter?

you succ the tube

1-5V (ohms law, 4-20mA X 250Ohms - 1-5Volts)

[@marxsoles9041]

good

[@Ivan-vv6nd]

but how to calibrate
