The 034B-ET, manufactured by Met One, combines a three-cup anemometer and vane into a single integrated package to measure wind speed and direction. This wind set is constructed out of lightweight aluminum and is designed for continuous, long-term operation for your applications.
对于此版本的034B风机,电缆终止于连接器中,并且是连接到ET107或ET106 ETO气象站的理想长度。
Read MoreThe 034B-ET monitors wind speed using a three-cup anemometer that contains a sealed magnetic reed switch. Rotation of the cup wheel produces a pulse that is directly proportional to wind speed. The frequency of the pulse is measured by the data logger pulse count channel, then converted to engineering units (mph, m/s, knots).
Wind direction is sensed with a potentiometer. With the precision excitation voltage from the data logger applied to the potentiometer element, the output signal is an analog voltage that is directly proportional to the azimuth of the wind direction.

信息包含在校准表differs with each sensor. For some sensors, the sheet contains coefficients necessary to program a data logger. For other sensors, the calibration sheet is a pass/fail report.
Most Campbell Scientific sensors are available as an –L, which indicates a user-specified cable length. If a sensor is listed as an –LX model (where “X” is some other character), that sensor’s cable has a user-specified length, but it terminates with a specific connector for a unique system:
If a sensor does not have an –L or other –LX designation after the main model number, the sensor has a set cable length. The cable length is listed at the end of the Description field in the product’s Ordering information. For example, the 034B-ET model has a description of “Met One Wind Set for ET Station, 67 inch Cable.” Products with a set cable length terminate, as a default, with pigtails.
如果电缆用特殊连接器终止用于唯一系统,则型号的末尾指定哪种系统。例如,034B-ET模型将传感器指定为ET107系统的034B。
并非每个传感器都有不同的电缆终端选项。可以通过在传感器产品页面的“排序信息”区域中查看两个位置来检查特定传感器的选项:
如果在-ET中提供传感器,-ETM,-LC,-LQ或-QD版本,则该选项的可用性反映在传感器型号中。例如,034b作为034b-et,034b-etm,034b-lc,034b-lq和034b-qd提供。
如果有可用的所有其他电缆终端选项将列在“电缆终止选项”下的传感器产品页面的“订购信息”区域上列出。例如,034B-L风装置具有-CWS,-PT和-PW选项,如034B-L产品页面的排序信息区域所示。
Note:As newer products are added to our inventory, typically, we will list multiple cable termination options under a single sensor model rather than creating multiple model numbers. For example, the HC2S3-L has a –C cable termination option for connecting it to a CS110 instead of offering an HC2S3-LC model.
This depends on the information contained in the calibration sheet:
Many Campbell Scientific sensors are available with different cable termination options. These options include the following:
Note:The availability of cable termination options varies by sensor. For example, sensors may have none, two, or several options to choose from. If a desired option is not listed for a specific sensor, contact Campbell Scientific for assistance.
