For high-volume car washes like automatic in-bays and express tunnels, sensors are a key component for efficiency and speed. By automating various aspects of the wash with sensing devices, a facility is able to safely process a high number of vehicles while maintaining safety and optimal customer experience. Banner engineering is a leading provider of quality sensors ideal for car washes. From vehicle detection and positioning solutions to more intricate applications like controlling water supply, air pressure, and chemical delivery, Banner offers a variety of sensor models with the exact ranges and specifications required to meet the needs of each system. Most have impressive features like quick disconnects, LED indicator lights, and acrylic lenses. Photoelectric sensors, also known as photo eye sensors, are the most commonly used type, and we carry an extensive selection to choose from. These high-quality sensors are compact, rugged, and reliable - built to withstand the rigors of the washdown environment! We also carry replacement cordsets in various lengths to wire your sensors.
Banner's QS30 Series has been the industry standard for vehicle detection, using high-powered infrared technology to verify vehicle positioning even in mist and steam. They boast tough housings and IP69K-rated quick disconnects that withstand constant water exposure and extreme temperature swings. Multiple sensors can be used concurrently, able to eliminate false trips by outside sunlight, ignore electromagnetic and radio frequency interference (EMI and RFI) from other automated car wash equipment, and be configured to eliminate crosstalk.
A photoelectric sensor system consists of an emitter and a receiver positioned so they face each other. The emitter, which holds a light source like an LED, shoots an invisible beam to the receiver. When that beam is interrupted by an object, it triggers an output signal. That signal controls the device or system it's connected to, doing things like turning it on or off, opening or closing it, or acting as shutoff function.
Photoelectric sensors are different from inductive sensors and ionization sensors. Inductive sensors use electromagnetic technology to detect only metal and are often used in close proximity to the objects they are detecting. Ionization sensors, most commonly found in smoke detectors, measure changes in the electrical current caused by excessive smoke disrupting an ionization chamber.
A common difficulty encountered when sensors fail is determining if it's the emitter or the receiver at fault. A simple way to determine which component is causing trouble is to take a picture of the emitter with your phone (make sure power is connected to the emitter). If you DON"T see a light coming from it, that means the emitter is probably not working correctly. If you DO see a light, you can safely assume that the receiver is the problem.
We offer Banner sensors with as much as a 200' sensing capability! We have you covered for virtually any situation that you'll come across.
