What are the different types of level sensors?
1. Optical Level Switches Pros – Compact, no moving parts, high pressure and temperature capability, can detect tiny amounts of liquids Cons – Invasive as the sensor requires contact with the liquid, requires power, certain thick substances can cause coating on the prism. Applications – tank level measurement and leak detection applications
How does a switch work in a level sensing system?
The switch operates very simply. Inside the sensor housing is an LED and a phototransistor. When the sensor tip is in air, the infrared light inside the sensor tip is reflected back to the detector. When in liquid, the infrared liquid is refracted out of the sensor tip, causing less energy to reach the detector.
How does a capacitance level sensor work?
They measure the change in capacitance between two plates produced by changes in level. Two versions are available, one for fluids with high dielectric constants and one with low dielectric constants. Capacitance level sensors work with a range of solids, liquids, and mixed materials.
What can be detected by a level sensing device?
Fluids that have historically been known to be extremely challenging to detect such as soap containing bubbles/foam, milk, and sticky substances such as glue and ink are now proving possible and easier to detect with the variety of level sensing technologies available. If playback doesn’t begin shortly, try restarting your device.
Where is the level sensor on the head unit?
Locate where the focus tube will be positioned on the underside of the head unit. Place the focus tube so that the inner threaded side of the tube will be tightened over top of the threaded projection from the level sensor on the underside of the head unit (Focus Tube colors vary).

Where can I find the NSN part number?
ISO Group has comprehensive parts databases, including an up-to-date National Stock Number NSN Database, that can be searched by NSN, NSN Part Number, NIIN and many other combinations of information such as NSN Part or NSN Part Number.

We talked about seven different types of level switches and their applications. Some level sensor applications can overlap and when deciding on a sensor it is important to identify the product that you are sensing and the type of feedback that your application requires.
What are the different types of sensor technology?
Type of Sensor – the presence of an object can be detected with proximity sensors, and there are several kinds of sensor technologies including here ultrasonic sensors, capacitive, photoelectric, inductive, or magnetic.
What kind of sensors should not be used in dirty applications?
:If the application is dusty or dirty, ultrasonic technology is very well suited. Vision sensors and photoelectric sensors should be avoided for very dirty applications.
How to choose the right object detection sensor?
: SICK, Inc. Choose the Right Object Detection Sensor 10 Photoelectric Sensors :A photoelectric sensor responds to a change in the intensity or angle of the light received :Photoelectric sensing requires an emitter (to generate light) and a receiver (which “sees” the light from the emitter)
