WHAT IS REVERSE POLARITY PROTECTION?

Accidents and mistakes can happen when connecting a power supply to a pressure, vacuum, temperature transducer or transmitter device. If the scenario occurs that the polarity of the DC supply voltage to transducer or transmitter is reversed, it’s critically important that the connected device is protected. Reverse polarity protection is an internal circuit that ensures that the device is not damaged if the power supply polarity is reversed. The reverse polarity protection circuit cuts off power to the sensitive electronic circuits in the transmitter or transducer. It’s an important feature, because significant power can be available in DC power supply systems in many industrial installations and besides permanent damage to the connected device there can be risk of fire if the device is not protected against reverse polarity. 


Sens4 offers pressure, vacuum and temperature transmitters with reverse polarity protection. For more information see our product portfolio.
