What is a NAMUR device?
Answer: A NAMUR sensor is a 2-wire proximity sensor that is usually powered by 8 VDC. When the sensor detects the target, the current flow through the sensor drops to less than 1.2 mA. When the target moves away from the sensor and is not detected, the current flow increases to above 2.1 mA.
What is NAMUR circuit?
A NAMUR proximity sensor has a switching circuit similar to a typical proximity sensor, but instead of making and breaking an external circuit, the switching circuit is used to change the output current flow by altering an internal resistor network.
What is NAMUR certification?
NAMUR, the international association and standards body for automation technology users in the process industry, establishes recommendations for equipment deployed in the European chemical market based on operating norms and user requirements.
What is NAMUR voltage?
NAMUR Sensor The sensor is operated with a nominal operating voltage of 8.2 V.
What is NAMUR full form?
User Association of Automation Technology in Process Industries (NAMUR) (German: Interessengemeinschaft Automatisierungstechnik der Prozessindustrie), established in 1949, is an international association for users of automation technology and digitalization in the process industries with its headquarters in Leverkusen.
What is NAMUR setting?
NAMUR NE43 is a standard used to define the operating AO-LL and AO-UL values. To be compliant to NAMUR NE43, the transmitters are set in the factory to have a AO-LL and AO-UL of 3.8 mA and 20.5 mA respectively. These values are set and can not be changed.
What is 2 wire NAMUR?
These are analogue output switches called ‘NAMUR’ output switches. These are 2 wire DC switches consisting only the sensor part of the total circuit. Due to their low current and voltage, these switches are most suitable in explosive or hazardous areas, when used with switching amplifier confirming to DIN 19234.
What is NAMUR 43?
NAMUR NE43 is a standard used to define the operating AO-LL and AO-UL values. Similar to the Standard Analog Output Signal, NAMUR NE43 compliant transmitters are designed to output signals greater than the 4 to 20 mA “Base” signal, allowing for a small amount of Signal Saturation.
What is NAMUR recommendation?
NAMUR Recommendations (NE) provide an explanation of the state of the art and regulations for member companies as well as for manufacturers, scientists and authorities. NAMUR worksheets (NA) are an aid in the form of checklists and instructions for practical work in companies.
What is NAMUR standard?
NAMUR is an acronym for the User Association of Automation Technology in Process Industries, which provides an industry-wide standard for automated valve technology. A NAMUR non-amplified sensor supplies two different signal levels, depending on the switch state.
What is NAMUR NE43 standard?
What is NAMUR 107?
NE 107 is a recommendation from the NAMUR organization for “Self-Monitoring and Diagnosis of Field Devices” explaining how to make use of diagnostics in intelligent devices. Why display device diagnostics to the operators?
