Built For Reliability In Tough Applications

Ideal For Extreme Vibration

  • In the world of heavy industry, there are a lot of big machines that can produce powerful vibrations. Big pumps, drilling rigs, large engines, you name it! The PT- 400 is built for durability in these tough applications. To ensure maximum reliability, we zero in on the details – like using the best steel and the strongest laser welds. We carefully tie all wires down using a variety of methods. All soldering is done by IPC J-STD-001 certified technicians. We even fill the entire housing with industrial potting to dampen vibrations.

Can Take The Shock

  • Vibrations aren’t the only benefit of this vehicle’s strong construction. The PT-400 handles shock well, too. That’s important in environments where things like water hammers or plain and simple rough handling are commonplace.

Global Hazardous Area Certifications

  • The PT-400 Heavy Duty Pressure Transducer is certified compliant with Class 1, Zone 0 requirements in North America, ATEX in Europe, and IECEx for just about anywhere else. So it’s ideal for markets like the Oil & Gas or Water and Wastewater industries that deal with flammable gases.
