Proximity Sensors

Proximity sensors are devices that can detect the presence or absence of objects without physical contact. They can detect nearby objects in a wide variety of applications, for example, sensing objects in machines, monitoring fluid flow, tank level measurements, and material levels in production lines.

9984-4900 Application Field and Working Principle

The 9984-4900 is a unique proximity sensing solution for non-contact level sensing applications. It is a two-wire, high-power DC ultrasonic transducer that works on the principle of acoustic reflection. The transducer is composed of two parts –an ultrasound transmitter and a receiver. When the ultra-high frequency waves emitted by the transmitter encounter an object, the wave is reflected back to the transducer. The receiver picks up the reflection and then sends it to a controller. The controller then interprets the reflection and determines whether there is an object or not.

The 9984-4900 is ideal for a wide range of level sensing applications in liquids, solids, and granular materials such as silos, tanks, pipes, plating tanks, and brine tanks. The 9984-4900 is highly reliable, resistant to extraneous noise, and can be easily incorporated into existing systems. It is also remarkably energy efficient with a power consumption of less than 1 watt.

The 9984-4900 also offers several advantages over traditional mechanical solutions such as float switches. It is contactless and therefore requires little maintenance and is not affected by fouling or clogging. In addition, it has high sensitivity and can detect objects over a wide range, from a few centimeters to several meters. It also has a wide operating temperature range, from -40°C to +150°C.

The 9984-4900 has several features that make it a great choice for level sensing applications. It is powered by a wide range of AC or DC power, can be connected to industrial networks, and has an RS-485 port for communication. In addition, it is very easy to install and requires no calibration or special tools.

In conclusion, the 9984-4900 is an excellent choice for non-contact level sensing applications due to its high accuracy, ease of installation, and reliable operation. Its wide operating temperature range and low power consumption make it a versatile and efficient solution for a wide range of applications.
