Ultrasonic Level Switches
With decades of experience in level measurement and process control, iCenta Controls supplies reliable ultrasonic level switches for dependable point-level detection in liquids and bulk materials. Using non-contact ultrasonic technology, these devices provide accurate switching without moving parts, making them ideal for a wide range of industrial applications. Commonly used for high-level alarms, low-level protection, and process automation, our ultrasonic level switches deliver reliable performance, simple installation, and minimal maintenance requirements.
What is an Ultrasonic Level Switch?
An ultrasonic level switch is a device used to detect the presence or absence of material at a specific level within a tank, vessel, or silo. Unlike continuous level measurement devices, ultrasonic level switches are designed to trigger an output when the product reaches a predetermined point.
Due to their operating without direct contact with the material being measured, ultrasonic level switches are particularly well suited to applications involving corrosive liquids, difficult process conditions, or situations where mechanical devices may be prone to wear.
How Do They Work?Â
They operate by transmitting high-frequency sound waves towards the surface of a liquid or bulk material. When the signal reflects to the sensor, the device determines whether the product has reached the desired switching point.
Once the preset level is detected, the switch activates an output signal that can be used to trigger an alarm, start or stop a pump, or control another process function. This non-contact measuring principle provides reliable operation with minimal maintenance and no moving parts.
