PT-500 Prevents Storm Flooding

PT-500 Submersible Pressure Transducer manages flood water in Minami tunnels

When the city of Miami Florida opened a ¾ mile tunnel roadway 127 ft. under the bay they knew they would need to have a plan in place to prevent flooding in case of a storm or hurricane. The tunnel is four lanes wide and extends from the mainland to the cruise line ports....

From the Lab: Developing the PT-500 Submersible Pressure Transducer

The PT-500 submersible pressure sensorToday we want to give you a sneak peak into the lab at APG. Our submersible pressure transducer has been around for a while now, but, like many of our sensors, it is under continual improvement. We want to give you a look at some of the decisions we made while developing our submersible.

A New Transducer Face

We switched up the actual transducer technology to MEMs sensing elements. The move did a few things for the sensor. Overall, the transducer is much more stable, and less prone to drift. Additionally, it’s more durable. The sensor’s diaphragm can be handled without damage to the sensor.

From the Lab: Lightning Transient Protection for the PT-500

Lightning strikes can disable electrical equipment if not properly designed.

Every year there are at least 20 million cloud-to-ground lightning strikes. Lightning can generate millions of volts and hundreds of thousands of amps per strike.

When lightning hits the ground, a near or direct hit will usually severely damage or destroy a sensor. With an indirect hit, a current pulse will travel a great distance before dissipating into the ground, and while less destructive than a direct hit, can wreak havoc on electrical instrumentation.
