PT-500 Submersible Level Sensors With Unique Removable And Reusable Cage Now CSA Certified For Hazardous Locations

Logan, UT - PT-500 Submersible Liquid Level/Pressure Transmitters from Automation Products Group, Inc. are now cCSAus certified for use in Class I, Div. 1, Groups C and D, and Class I, Zone 0, Group IIB hazardous locations. Class I, Div. 1, Group C, and Class I, Zone 0, Group IIB atmospheres contain ethyl-ether vapors, ethylene, or cyclopropane. Class I, Div. 1, Group D atmospheres contain gasoline, hexane, naptha, benzene, butane, propane, alcohol, acetone, benzol, lacquer solvent vapors or natural gas.

The PT-500 features a vented, watertight cable and delivers a high precision 4-20mA solid-state signal while submerged up to 450 ft. A unique (patent pending) removable stainless steel cage connects to the sensor with a simple snap ring and enables users to save significantly on sensor replacement costs.

"The stainless steel cage is a fairly expensive piece of hardware that typically cannot be removed from the sensor, or reused. Historically that has meant that each time a sensor needed to be replaced in the field so did the cage at an added cost of $200 or so," says Karl Reid, Engineering Manager. "Because these types of sensors are used in some nasty environments they tend be replaced on a fairly regular basis, so being able to reuse the cage can deliver exponential savings over a period time," he says.

Rugged IP68 protected PT-500 transmitters deliver accuracy of 0.50% of span, and are temperature compensated to ensure accuracy and long-term stability under extreme temperature variations. Simple-to-install surface mount technology provides added protection from shock and vibration.
