Pressure transmitters are used in both process and storage environments. The PT-400 is for external mounting on the tank and is designed for extreme environments. This heavy-duty pressure transducer can handle dirt and fine dust, water spray and wash downs, outdoor installation in inclement weather, hazardous locations and high vibration. The PT-400 is appropriate for the demanding conditions and hazardous classified areas of the oil and gas industry. The PT-500 submersible pressure sensor can be used in just about any liquid. Common, yet nasty, applications include wastewater lift stations and leachate tanks at landfills. The PT-L amplified output pressure sensors are designed for industrial applications in pressure ranges up to 40,000 psi, and are suitable for both liquids and gasses. They provide accurate measurement and a long life expectancy at a low cost.
