Ultrasonic level transmitters use sound waves to measure the distance between the sensor and the liquid surface.

• Ultrasonic waves are sent from the transmitter towards the liquid surface.

• The waves are reflected back to the sensor by the surface of the liquid.

• The time taken for the waves to return is used to calculate the distance to the liquid surface.

• The level of the liquid is then determined based on this distance measurement.

• Common applications include monitoring levels in ...read more

Ring topology is a network configuration where each device is connected to exactly two other devices, forming a circular loop.

• Each device in the network is connected to exactly two other devices, creating a circular loop.

• Data travels in one direction around the ring.

• If one device fails, the entire network can be affected.

• Examples: Token Ring network, SONET ring network.

Layer protection refers to the use of multiple layers of security measures to protect a system or device.

• Layer protection involves implementing multiple levels of security measures to safeguard against potential threats.

• Each layer of protection adds an additional barrier for unauthorized access or attacks.

• Examples of layer protection include firewalls, encryption, access control, and intrusion detection systems.

IP rating refers to the degree of protection provided by equipment against solid objects and liquids.

• IP rating stands for Ingress Protection rating

• It consists of two digits, the first indicating protection against solids and the second against liquids

• For example, IP67 means the equipment is dust-tight and can withstand immersion in water up to 1 meter depth for 30 minutes
