Duct Air Flow Measuring Probe The DAFM Model Duct Air Flow Measuring Probe : Uses evenly distributed total and static pressure measuring points to deliver an accurate measurement of flows in a duct. The Air Flow Measuring Probe can be completely installed from outside of the duct making it very easy to install. With its lightweight and durable construction in addition to its ease of installation, this product lends itself to being used in the HVAC industry. These air flow measuring probes may be ordered to fit into either round or rectangular duct installations. Installation: When you unpack the Model DAFM Duct Air Flow Measurement Probe ensure that there is no visible damage from shipping. Inspect each sensing point on the probes to ensure that they are not filled with debris from shipping. If there is obvious shipping damage, the probe must be replaced prior to use in order to avoid inaccurate measurements. Please contact Dwyer Instruments, Inc. if it is necessary to replace your air flow measurement probe. Rectangular Duct Models: Determining Probe Number and Placement for Rectangular Ducts To determine the number of probes you need please consult the chart below. In order to determine where to place your probes, divide the short duct dimension by number of probes. Divide the result by two and this will be the distance from the side of the duct to the first probe location. The next probe will be placed two times the resulting distance from step two from the first probe. So, if the first probe was placed 4 ̋ from the side of the duct, your next probe would be placed 8” from the first probe, or 12 ̋ from the side of the duct. Continue this pattern until you have determined all probe locations. Rectangular Duct Probe Installation: Cut 4 ̋ X 1 ̋ holes at locations calculated above in side of duct. Place silicon bead around holes. Slide DAFM into holes and screw four self drilling screws into duct to attach DAFM. Connect 1/4 ̋ OD plastic tubing to barb fittings on DAFM. Check all fittings and tubing connections for leaks using a leak detector. Tee all high and low ports into one high and one low line and connect to transmitter or gage. The devices should be checked once a year for build-up of dirt of debris common in an HVAC system. Circular Duct Models: Determining Probe Number and Location for Round Ducts Note that in round ducts only two probes are needed. The quantity of probes needed does not depend on size of the duct. Locate probes 90 degrees apart. See Figure 2 for an example. Calibration: Sometimes field calibration may be required if the probe is installed in a bad location i.e. immediately downstream of an elbow. In order to calibrate, you must either perform a traverse of the duct or a sum of the air registers and compare this with the DAFM output. Then, you must make the correction to the effective area in the computer to make up for the error. Maintenance: Upon final installation, the device should be checked once a year for a build up of dirt or debris that can be common in an HVAC system. Also check the mounting stability once a year. Other than this no routine maintenance is required. The DAFM model is not field serviceable and should be returned if repair is needed (field repair should not be attempted and may void warranty). Be sure to include a brief description of the problem plus any relevant application notes. Contact customer service to receive a return goods authorization number.

The Series AVU Air Velocity Transmitters from Dwyer Instruments are suitable for measuring air velocity within a duct and giving 4-20 mA or 0-10 V linear outputs. A typical application would be in a VAV air conditioning system. The transmitters operate by measuring the heat loss from one of two sensing elements in the airstream and hence calculating the air velocity. The special design of these elements makes the transmitter accurate over the whole air velocity range and gives excellent immunity to drift. The sensing elements are clad in metal ensuring a long service life and enabling the sensors to be cleaned easily. Installation:Electromagnetic CompatibilitySeries AVU Air Velocity Transmitters have built in immunity to electrical interference. However, to achieve full immunity meeting the standards described below, a screened cable must be used correctly. The cable screen must be earthed at the enclosure of the controller/power supply and connected to the screen inside the AVU casing using the procedure described on the back page. The inside of the transmitter and the sensing elements near the end ofthe probe must be protected from electrostatic discharge at all times.

Carbon Dioxide and Temperature Transmitter

The SERIES CDT Carbon Dioxide and Temperature Transmitters accurately monitor the CO2 concentration and temperature in indoor environments to help achieve energy savings. For increased sensor accuracy, a single beam dual wavelength nondispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied* and unoccupied buildings against light source aging effects. The single beam dual wavelength sensor technology provides the highest level of accuracy compared to Automatic Baseline Correction methods which can unintentionally shift the calibration based on CO2 levels and barometric pressure conditions. In order to achieve a higher level of accuracy, the Series CDT includes digital barometric pressure adjustment and the ability to field-calibrate the sensor. For applications that require visual indication, the wall mount configurations of the Series CDT can be ordered with an integral LCD display. Push buttons are standard on all configurations of the transmitters for access to the menu structure, but wall mount configurations can be ordered without the buttons. To prevent tampering, the action of the buttons can be locked out using an internal dip switch selection.
For buildings occupied 24 hours per day, it is recommended that calibration be verified every 6 to 12 months depending on application.

Single beam dual-wavelength sensor advantages:

Automatically corrects for aging effects in occupied and unoccupied buildings. Perfect for hospitals and manufacturing plants that are occupied 24 hours per day
Measures actual unfiltered light intensity directly. Eliminates error from incorrect assumptions of gas concentration in theoretical logic assumption methods

Features:

Single beam dual wavelength NDIR sensor eliminates draft due to light source aging

Communicating Carbon Dioxide Detector The SERIES CDTA Communicating Carbon Dioxide Detector combines the function of three room sensors into a single, compact housing. Parameters include carbon dioxide, humidity, temperature, and temperature set point with override. By having field selectable Mtemperature set point with override. By having field selectable Modbus® and BACnet Communications, only four wires are needed for power and the communication signal. The communicating detectors can be daisy chained together to further reduce installation cost. In order to reduce the set up time, the RS-485 MAC address is set up using on board dip switches. A second set of dip switches are used to select whether output is Modbus® RTU or BACnet MS/TP communication protocols and to limit access to the set up menu. Like our Series CDT Carbon Dioxide Transmitter, the Series CDTA uses a Single Beam Dual Wavelength Non-Dispersive Infrared (NDIR) sensor to measure the carbon dioxide level. This technology can be used in installations that will be occupied 24 hours per day. For improved accuracy, the transmitter can be field calibrated to the environmental conditions of the installation. Also, the barometric pressure can be programmed to correct for altitude. The humidity uses a capacitive polymer sensor and the temperature is measured using a 10KO thermistor sensor. The humidity sensor is field replaceable without the need for additional calibration. Optional local and remote displays are available to display any of the parameters. For applications in which the building occupants aren’t familiar with CO2 concentrations, the LCD can be programmed to display temperature, humidity, or temperature set point instead.

Carbon Dioxide Temperature Transmitter The SERIES CDTR Carbon Dioxide, Relative Humidity and Temperature Transmitters reduce the number of sensors mounted on a wall or in a duct. By combining CO2, RH, and temperature in one device, system integrators are able to reduce installation time while lowering material cost at the same time. Like our popular Series CDT Carbon Dioxide Transmitter, a single beam dual wavelength non-dispersive infrared (NDIR) sensor is used to automatically correct the measurement in both occupied* and unoccupied buildings against light source aging effects. In order to achieve the best possible accuracy, the Series CDTR also includes digital barometric pressure adjustment and the ability to field calibrate the sensor. Universal outputs for both carbon dioxide and relative humidity allow users to select the transmitter output to be 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC to work with virtually any building management controller. Additionally, passive thermistor or RTD sensor can be ordered for a temperature output. For applications that require visual indication, the wall mount configurations of the Series CDTR can be ordered with an integral LCD display. The display can be configured to display temperature only, relative humidity only, CO2 only, CO2 and humidity, or CO2 and temperature. Push buttons are standard on all configurations of the transmitters for access to the menu structure.
