LOGAN, UT ‚– LPU-2428 Loop Powered Ultrasonic Level Sensors from Automation Products Group, Inc. (APG) 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.
LPU-2428 sensors feature microprocessor control to internally perform volume, flow, and totalization calculations. They provide a 1 to 25 ft. (0.3 to 7.62 m) detection range on liquids and a 1 to 10 ft. (0.3 to 3.0 m) detection range on solids. These sensors are
well suited for environmental monitoring, water and wastewater control, and liquid tank measurement applications. They are also suited for other industrial and process control applications where liquid volume or flow needs to be monitored and controlled.
LPU-2428 sensors feature a rugged PVDF (Kynar) transducer housing and PC/PET chemical resistant sensor housing, and are easy to install using industry standard 2-inch NPT fittings. These sensors can operate in temperatures from -40 to 140‚ºF (-40 to 60‚ºC) and deliver 0.1 in. (2.5 mm) resolution with accuracy of ‚± 0.25% of the detected range, and response time of 0.6 to 3 seconds depending on the output range.
The LPU-2428 features internal temperature compensation to automatically account for changes in ambient temperature, as well as filtering options to account for other variables such as waves on a liquid or tank irregularities. They are unaffected by the color/translucency, dielectric constant, specific gravity or viscosity of the target. Internal parameters are setup using a remote keypad & display unit.
