Overview

The 27106T Vertical Propeller Anemometer, manufactured by R. M. Young, is a low threshold precision air velocity sensor that is especially suited for your applications where you need to monitor the vertical wind component. It connects directly to a Campbell Scientific data logger, which measures the 27106T's signal and converts the signal to engineering units (mph, m/s, knots).

Benefits and Features

  • Compatible with most Campbell Scientific data loggers
  • Especially suited for monitoring vertical wind, but can be mounted to monitor the wind in whatever direction is desired
  • Carbon-fiber thermoplastic (CFT) propeller provides greater range and durability than other propeller anemometers offered by R. M. Young.

The "-L" on a product model indicates that the cable length is specified at the time of order.

Detailed Description

The 27106T measures air velocity using a fast-response, four-blade helicoid propeller that drives a high-quality tech-generator transducer. The transducer converts the propeller’s rotation to a dc voltage that is linearly proportional to air velocity.

The 27106T should be oriented with the propeller facing the predominant flow of air being measured. Its propeller responds only to the component of the air flow, which is parallel to the axis of its rotation. Off-axis response closely approximates a cosine curve with appropriate polarity. With perpendicular air flow, the propeller does not rotate.

Mounting

The 27106T is shipped with a 3/4 inch IPS threaded pipe for mounting. The pipe can be attached to a CM202, CM202SS, CM203, CM204, CM204SS, or CM206 crossarm using a 1049 Nu-Rail fitting or CM220 Right-Angle Mounting Bracket.

27106吨包括连接器/耦合器的伴侣to the sensor and to the 3/4-inch IPS threaded pipe. The customer specified length of cable is soldered to the pins on the connector and the cable threads through the coupler and out the pipe.

  1. What are the multipliers and offsets for the 27106T-L?

    For this information,refer to the “Wind Speed Multiplier and Offset” section in the27106T instruction manual.

  2. Where are the available cable termination options listed for a particular sensor?

    Not every sensor has different cable termination options. The options available for a particular sensor can be checked by looking in two places in the Ordering information area of the sensor product page:

    • Model number
    • Cable Termination Options list

    If a sensor is offered in an –ET, –ETM, –LC, –LQ, or –QD version, that option’s availability is reflected in the sensor model number. For example, the 034B is offered as the 034B-ET, 034B-ETM, 034B-LC, 034B-LQ, and 034B-QD.

    All of the other cable termination options, if available, are listed on the Ordering information area of the sensor product page under “Cable Termination Options.” For example, the 034B-L Wind Set is offered with the –CWS, –PT, and –PW options, as shown in the Ordering information area of the 034B-L product page.

    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.

  3. What are the different cable length choices available for Campbell Scientific sensors?

    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:

    • An –LC model has a user-specified cable length for connection to an ET107, CS110, or retired Metdata1.
    • An –LQ model has a user-specified cable length for connection to a RAWS-P weather station.

    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.

    If a cable terminates with a special connector for a unique system, the end of the model number designates which system. For example, the 034B-ET model designates the sensor as a 034B for an ET107 system.

    • –ET models terminate with the connector for an ET107 weather station.
    • –ETM models terminate with the connector for an ET107 weather station, but they also include a special system mounting, which is often convenient when purchasing a replacement part.
    • –QD models terminate with the connector for a RAWS-F Quick Deployment Station.
    • –PW models terminate with the connector for a PWENC or pre-wired system.
  4. Is a replacement mounting pipe for the 27106T-L available?

    Campbell Scientific does not currently manufacture or stock this item. The 27106T-L is shipped from R. M. Young with the mounting pipe attached. Contact R. M. Young directly for assistance.

  5. How does the 27106T-L make its measurement?

    The anemometer uses a single-ended voltage measurement.

  6. What are the different cable termination options available for Campbell Scientific sensors?

    Many Campbell Scientific sensors are available with different cable termination options. These options include the following:

    • The –PT (–PT w/Tinned Wires) option is the default option and does not display on the product line as the other options do. The cable terminates in pigtails that connect directly to a data logger.
    • In the –C (–C w/ET/CS110 Connector) option, the cable terminates in a connector that attaches to a CS110 Electric Field Meter or an ET-series weather station.
    • In the –CWS (–CWS w/CWS900 Connector) option, the cable terminates in a connector that attaches to a CWS900-series interface. Connection to a CWS900-series interface allows the sensor to be used in a wireless sensor network.
    • In the –PW (–PW w/Pre-Wire Connector) option, the cable terminates in a connector that attaches to a prewired enclosure.
    • In the –RQ (–RQ w/RAWS Connector) option, the cable terminates in a connector that attaches to a RAWS-P Permanent Remote Automated Weather Station.

    Note:的效果ability 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.
