The Optical Liquid Level Sensor is a solid-state technology which uses an infra-red LED and phototransistor to detect the presence or absence of liquid. In this article, we will cover what the level sensor is used for and the types of applications they are commonly used in.
An optical liquid level sensor is used to detect the presence or absence of almost any type of liquid, oil or water based. The main purpose for these level sensors fall into two main categories; leak detection and single point level control (maximum or minimum). |
As mentioned above, the type of applications falls into two main categories; leak detection and level control. The number of leak detection and level control applications PST are confronted with each day is endless, however we have detailed below the most common types we are asked about. If your application is not listed below, please contact us and we will be happy to discuss your requirements.
TelecommunicationsDetecting rainwater leaks at an early stage in outdoor telecommunication units and so preventing loss of service or potentially expensive damage is an application PST is very familiar with. The increased use of small and metrocell technology has resulted in a growing number of telecommunication enclosures being deployed in locations which are difficult to access and not subject to regular inspection. |
Robotic Automation SystemsIndustrial robotic systems is another application in which PST has a lot of experience with. Industrial robots are hugely expensive to install to is crucial that they are operated and maintained correctly – any “down-time” can be costly. |
Peristaltic PumpsPeristaltic pumps are suitable for dispensing, metering and general transfer of liquid media. They confine the media to the tubing, so that the pump cannot contaminate the fluid and the fluid cannot contaminate the pump. The contamination-free pumping makes peristaltic pumps particularly suitable for use in high purity applications, including the transfer or dosing of chemicals and additives in the food, pharmaceutical and semiconductor industries. |
In level control and detection applications, the liquid level of a tank or vessel will vary at a continuous pace over a period. In order to know when failure occurs of when the level goes dangerously high or low, it is critical to have a level control monitoring solution in place to prevent expensive damage, flooding or run dry situations.
