MODEL 5303-B CONTINUOUS, CAPACITANCE LIQUID LEVEL SYSTEM The model 5303-B System is a new version of our highly reliable and most popular continuous liquid level control system. It is by far the most versatile system; below is a list of its most outstanding features: Miniature Size: The transmitter is a fraction of the previous size (1 in. wide by 2 in. long) utilizing the latest surface mount technology, and providing a variety of industry standard outputs, and fully adjustable control setpoints. Versatile: All the options are in the same transmitter PC Board, plus the same transmitter can handle probes as small as one inch long, to 60 feet long with a minor component change. Low Cost: By combining several features into one module, and utilizing the latest technology, manufacturing costs are greatly reduced when larger quantities are made. Reliable: Because have been are innovators in capacitance systems for over 34 years with several U.S. patents, and our experience in hundreds of different applications, we have achieved constant improvement in the performance of our systems. We have also had to continuously keep up with the ever-changing electronics technology. SPECIFICATIONS: Accuracy: ±0.1% of Span, or 0.1 inch with most probe systems. Resolution: ±0.1% of output. The ultimate resolution depends on the output control device, i.e., readout, computer, or PLC (programmable logic controller) Power in: 10 to 36 VDC, typical @ less than 12 mA. The circuit has an internal voltage regulator, and input voltage polarity reversal protection. Output, Std.: 0-5VDC Outputs, Opt.: 0-1VDC, 1-5VDC, 4-20 mA Other, Special request. Setpoints: One or two, fully adjustable, over the span range. These are open collector, FET Solid state switches with a nominal output of 5 Amps. Dimensions: PCB for analog output and setpoints: 1.0"X1.5". PCB for above and 4-20mA: 1.0"X2.0". Probes: Probes are made to order, size and configuration depend on the application. Some are rigid, and others are flexible. All probes are made with Teflon coverings. | ||||
