What is a NAMUR signal?
NAMUR is a signaling standard, used primarily on proximity and limit switch devices. It outputs a current signal depending on the state of the switch. The switching spec is >2.1mA (typically but not always for NC) and <1.2mA for the opposite switch state.
What is NAMUR output type?
NAMUR is a type of sensor output that gives an on or off indication. NAMUR is a German acronym for (normenarbeitsgemeinschaft für Mess- und Regeltechnik in der Chemischen Industrie). This translates to: Standardization Association for Measurement and Control in Chemical Industries.
What is NAMUR type limit switch?
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 voltage?
The NAMUR input module has to implement the following functions: • Deliver a regulated 8.2-V output voltage at no load with a 1-kΩ source impedance. • Limit the current in case of a short-circuit load to a current below 10 mA.
What is NAMUR instrumentation?
How does a Namur sensor work?
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 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?
How does Namur sensor work?
What is NAMUR transmitter?
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 valve?
A NAMUR solenoid valve is directly mounted to pneumatic actuator inlet/outlet ports. The function of a NAMUR solenoid valve is to control media flow: the valve itself is controlled by an electric solenoid, which opens or closes the valve, by controlling the amount of air thru a pilot to the pneumatic actuator.
