High-temperature proximity switches, due to their ability to withstand high temperatures, are suitable for some high-demand occasions and are widely used in metallurgy, machinery, mining, electric power, railways, military industry, textiles, papermaking, chemicals, plastics and other industries. Among them, the 330194 high-temperature proximity sensor is Bently 3300XL 8mm high-temperature resistant sensor, which belongs to the 3300 XL 8 mm Extended Temperature Range (ETR) eddy current probe. Then, what are the six key points for the installation and commissioning of Bently Nevada 330194 series that our technicians need to pay special attention to?
-
Torque range: To avoid damaging the proximity switch during installation, do not exceed the given tightening torque.
-
Rated sensing range (sn): When a metal part approaches the sensing surface of the proximity switch, the distance within which the output state of the switch changes is the rated sensing range. In the sensing area, the proximity switch responds to the approaching metal part, that is, changes the output state.
-
Repeat accuracy of two measurements under standard conditions: The difference between the measured values should be less than 10.
-
LED display: The device has an LED status indicator when the ambient temperature is up to +130°C. When the LED light is no longer on, it indicates that the temperature has reached the maximum. This process can protect the device from damage.
-
Correction factor: It depends on the type, internal structure, size and geometry of the detected object's material. If a material different from steel (1.0037) is used, the correction factor specifies the change in detection distance. To establish an approximate sensing range different from that of ST37 material, the sensing range of ST37 must be multiplied by the corresponding correction factor.
-
In case of current overload, a built-in protection can prevent the proximity switch from being damaged, and the switch point changes due to environmental changes. At the same time, if the connection terminals are reversed, a built-in protection can prevent the proximity switch from being damaged.
