Namur signal

We take a closer look at NAMUR sensors, providing insights into their functionality and highlighting their significant roles across asx:nec industrial sectors. Discover the underlying technology behind NAMUR sensors and their importance in different industries. Their initial focus was on setting standards for how different devices connect and work together, namur signal, such as namur signal mA technology and proximity switches. They did this by forming working groups in four different areas to come up with recommendations and guidelines to improve technology development and integration.

One could be easily fooled by assuming that a NAMUR sensor is a typical proximity sensor because they look very much alike. But physical shape and appearance are the only characteristics they have in common. As illustrated in our animation, the proximity sensor acts just like a simple switch. When the target is away from the sensor, the switch is open. When the target is close to the sensor, the switch is closed. In most industrial applications today, a proximity sensor is not connected to an actual load resistance but is connected to an input of a PLC or DCS Digital Input Module. If you are interested in the exact description and its English translation, you can find it easily on the internet.

Get prepared for the challenges of Industry 4. NAMUR sensors with this output characteristic are marked with "N0" normally-closed characteristics or "N1" normally-open characteristics in the type designation. Note: In explosion-protection applications, the operating location of the intrinsically safe NAMUR sensor is located in the explosion-hazardous area. The isolated switch amplifier must be installed outside the explosion-hazardous area. NAMUR sensors are usually connected to external switch amplifiers that convert the current variation into a binary output signal.

As can be seen, the connection has two wires only since these sensors have current and not voltage outputs. The power supply necessary for the functioning of the electronics inside the sensor is also conveyed through these two wires. In this case, as the distance S between the sensor and the object to be detected increases, there is an increase in the current in the sensor itself. Such a low output impedance is intended and aimed at avoiding, in the event of a fault, the creation of possible ignition sources in the event of a fault. Of course, for the correct use of devices with NAMUR output, it is necessary to use appropriately designed hardware. The normative reference regarding the electrical output parameters of a NAMUR sensor is the EN Low-voltage switchgear and controlgear — part control circuit devices and switching elements — DC interface for proximity sensors and switching amplifiers NAMUR.

Thank you for requesting a quotation. These changes in current levels are then picked up by the switch amplifier and converted into a clear signal that can be used with other equipment downstream. Usually, NAMUR output products which include encoders and proximity sensors are used in classified hazardous location areas which have explosive gas, dust, or fibers present. Send request. Capacitive sensors sorted by connection. Siemens PLC in Hindi. Machine Monitoring System in Nutshell The online machine monitoring system is used for rotating equipment to monitor and protect the motors from critical vibration and temperatures. Industrial Networking. Start your learning journey today! NAMUR is a type of sensor output that gives an on or off indication. The other protection methods are containment explosion-proof or flame-proof enclosure andsegregation purging, pressurization, encapsulation, or oil filled. In order to provide these requirements an IS interface should be used to connect the sensor to the control system. Sharma March 27,

The mA analog signal is a widely spread standard in the industry for several good reasons. This type of signal is used by the majority of transmitters, PLCs, and distributed control systems. A variation of their output current between 4 and 20mA means that the transmitter is working perfectly fine and the process value to be measured is within the measurement range.

But physical shape and appearance are the only characteristics they have in common. Success Stories. Siemens PLC Course. It limits current so that the current is not capable of causing ignition in hazardous atmospheres. A NAMUR output sensor is required in installations where special safety measures are necessary locations with explosion hazard, or personal safety. These current levels are usually 1 mA with a target present and 3 mA without one. Motion Control. Your request has been sent successfully. Depending on the application, you could need any one of these products to detect your target, but if they meet the NAMUR standards, the output would be the same. We will get back to you by phone or email within 24 hours. The two most commonly used proximity sensors are the inductive proximity sensor and the capacitive proximity sensor.
