A common application of economical infrared-based optical interface point level sensors is detecting the sludge/water interface in settling ponds. By using pulse modulation techniques and a high power infrared diode, one can eliminate interference from ambient light, operate the LED at a higher gain, and lessen the effects of build-up on the probe.
The company manufactures electronic products for fabrication and process automation. It specializes in sensor manufacturing, such as sensors used in automatic doors in elevators, encoders, AS interfaces, RFID systems, [1] barcode solutions, [2] and explosion protection, [3] as well as components for the automotive industry, and plant ...
Most commonly, two types of electrode sensors are used, electrode-based sensors and inductive sensors. Electrode sensors with a static design are suitable for low and moderate conductivities, and exist in various types, having either two or four electrodes, where electrodes can be arrange oppositely, flat or in a cylinder.

Here the water is at the “top nut”, the maximum working level. Note the patterned backplate to help reading and toughened glass shroud. A sight glass or water gauge is a type of level sensor, a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.
Bill Byrge, an actor who appeared in many of the “Ernest” comedy films as “Bobby,” died on Thursday at the age of 92 in Nashville, Tenn. Byrge’s cousin, Sharon Chapman, confirmed his ...
(The Center Square) – Attorneys are expected to discuss jury instructions Thursday at the federal corruption trial of former Illinois House Speaker Michael Madigan in Chicago. Judge John Robert ...
It is designed for connecting simple field I/O devices (e.g. binary ON/OFF devices such as actuators, sensors, rotary encoders, analog inputs and outputs, push buttons, and valve position sensors) in discrete manufacturing and process applications using a single two-conductor cable.
