30. Dez. 2023 · A NAMUR sensor is a 2 wire proximity sensor that was developed to ensure safety in hazardous areas. NAMUR sensors are designed to be powered by a switching amplifier that limits the available voltage to 8.2 V. This voltage is kept constant by using two different current levels to indicate if the sensor is detecting a target or not.
NAMUR sensors are two-wire sensors that represent the switch state via specific current values as defined in the EN 60947-5-6 standard. NAMUR sensors are usually connected to isolated switch amplifiers that interpret the current values of the NAMUR sensor and convert them into discrete switching outputs. Together with a suitable isolated switch ...
NAMUR sensors are essential for precise monitoring and control in various industrial applications. The practical applications of NAMUR proximity sensors are varied and include presence detection, positioning, counting, speed detection, and distance measurement. 4 Example uses of NAMUR sensors in different industries: Factory automation.
2-wire sensors according to NAMUR (NAMUR sensors) are named after the User Association of Automation Technology in Process Industries (original German name: "Normenarbeitsgemeinschaft für Mess- und Regeltechnik der chemischen Industrie", in short: NAMUR). These are two-wire sensors according to EN 60947-5-6 (VDE 0660, part 212) that have a ...
NAMURセンサとは何ですか。 Answer (回答) NAMUR近接センサは危険な場所での安全性を確保するために開発されたセンサです。 NAMUR近接センサは、爆発性ガス、粉塵、または繊維が存在すると分類された危険場所区域で使用されます。 NAMUR近接センサは本質安全防爆仕様とされています。 では、NAMUR近接センサはどのようにして安全性を確保しているのでしょうか。 NAMUR近接センサは、一般的な近接センサとほぼ同様に動作しますが、出力条件がオープンまたはクローズではありません。 その代わり、NAMUR近接センサは、ターゲット位置に対応する2つの異なる電流出力レベルを生成します。 NAMUR近接センサは、危険区域で発火する可能性がないように電流を制限します。
12. Apr. 2018 · 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. There is a 0.9mA deadband for noise immunity.
