SeriesCDTR Carbon Dioxide/RH/Temperature Transmitter
NDIR CO2 Sensor, Universal CO2/RH Outputs, Optional Relay
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, andtemperature in one device, system integrators are able to lower installation time ofmounting multiple housings, while lowering material cost at the same time. Even with thethree sensors combined into a single unit, replacement cost is not increased due to thepluggable nature of the humidity sensor, which allows it or the temperature to be replacedat a fraction of the cost of a new CO2 transmitter.
Like our popular Series CDT Carbon Dioxide Transmitter, a single-beam dual-wavelengthnon-dispersive infrared (NDIR) sensor is used to automatically correct the measurement inboth occupied* and unoccupied buildings against light source aging effects. The single-beamdual-wavelength sensor technology provides a higher level of accuracy compared toAutomatic Baseline Correction methods which can unintentionally shift the calibrationbased on CO2 levels and barometric pressure conditions. In order to achieve the bestpossible accuracy, the Series CDTR also includes digital barometric pressure adjustmentand the ability to field-calibrate the sensor.
Universal outputs for both carbon dioxide and relative humidity allow users to select thetransmitter output to be 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC to work with virtually anybuilding management controller. Additionally, passive thermistor or RTD sensor can beordered for a temperature output. An optional relay for the carbon dioxide measurementcan be used to control exhaust fans, open actuated windows or dampers, or signal a lightor horn.
For applications that require visual indication, the wall mount configurations of the SeriesCDTR can be ordered with an integral LCD display. When ordering a duct mountconfiguration or a wall mount configuration without the display, the Model A-449 remoteLCD display can plug into the miniature connector port on the transmitter. The displaycan be configured to display temperature only, relative humidity only, CO2 only, CO2 andhumidity, or CO2 and temperature. Push buttons are standard on all configurations of thetransmitters for access to the menu structure, but wall mount configurations can be orderedwithout the buttons. To prevent tampering, the action of the buttons can be locked out usingan internal jumper selection. Menu items that can be accessed via the push buttons include:engineering units, relay output set points, display configuration, transmitter output scaling,ambient barometric pressure, and field calibration of the transmitter.
*For buildings occupied 24 hours per day, it is recommended that calibration be
verified every 6 to 12 months depending on application.

Magnetic Inductive Flow SensorNo Moving Parts, Frequency and 4 to 20 mA Output, Maintenance-Free
Series MFS Magnetic Inductive Flow Sensor is a compact, low cost alternative topaddle wheel sensors. Unlike sensors with moving parts, the MFS can be applied inapplications dealing with contaminated media. This series provides a reliable measuringtechnique, an obstruction free pipe cross-section, as well as a quick response time, makingthis series ideal for interference free operation. Any change in temperature, density,viscosity, concentration or electrical conductivity of the liquid, does not affect the outputsignal of this Magnetic Inductive Flow Sensor. This, in addition to its long-life cycle, makesthis series perfect for accurate reversible gauging of volume flow of conductive liquids inclosed piping.
Principles of Operation
The measuring pipe is in a magnetic field. If an electrically conductive medium with
a certain flow passes through the pipe, it passes at a right-angle to the magnetic
field, creating a voltage which is proportional to the average flow velocity and picked
up by two electrodes within the MFS. A frequency output signal is obtained that is
proportional to the flow (analog output option available).

• No moving parts
• No mechanical wear
• Maintenance-free

The Series TBS Insertion Turbine Flow Sensor comes in brass or stainless steel andhas an available “hot-tap” model. The TBS has Series SDF fittings available to fit pipe sizes3 to 40˝. Ruby bearings give the turbine a low coefficient of friction and long life. The lowfriction bearings also allow the Series TBS to handle a wide range for flow rates.Additional options for this meter include adapter fittings and valve assemblies. Series TBSis suitable for clean liquids and large pipe applications.
PRINCIPLE OF OPERATION
The Series TBS uses a turbine equipped with miniature magnets in the rotor blades
to measure flow. Liquid flow rotates the turbine and a sensor detects the passage
of the magnets resulting in a square wave output. The output signal can then be
combined with the Series RTI for flow rate and total, and the Series BAT for a 4 to
20 mA signal conversion.
APPLICATIONS
• Chilled Water Monitoring in Building Automation Systems
• Water & Wastewater Monitoring
• Aquariums, Water Parks
ACCESSORIES
• Series BAT, Blind Analog Transmitter, converts pulse output to 4 to 20 mA analog

The Series BAT Blind Analog Transmitter is a non-indicating, 4 to 20 mA transmitterfor use with the Series EFS2, IEFS, PDWS, TBS and FLMG. The BAT is easy to set upand can be either wall or meter mounted. It takes a pulse frequency output from thecompatible flow meters and converts it into a continuous 4 to 20 mA analog output signal.The frequency for the flowmeter output signal can be adjusted using four rotary switcheson the back of the transmitter and a microcontroller automatically scales all other valuesaccordingly. The microcontroller is also able to average inputs for more stable readingoutputs. The rate for averaging is adjustable and ranges from 2 to 16 seconds. Power forthe BAT is supplied by a current loop, making only 2 wires necessary. This unit featureshigh environmental protection with semi-flexible urethane potted electrical components.

The Model VRLS Vibrating Rod Level Switch is an economical choice in leveldetection of powders and bulk solids. The VRLS utilizes a piezoelectric crystal thatvibrates the rod at a natural frequency. Once the rod comes in contact with the material,the vibration will be dampened and the switch will change state. Once the rod is uncoveredby the material, the switch will revert to its normal state. Perfect for silo or hopperapplications, its probe design allows for self-cleaning, ensuring no build-up or bridging ofmaterial and accurate detection. Sensitivity is adjustable for detection ranging from largegranular material to small powders with low bulk densities. The failsafe mode can be setfor failure on high level or failure on low level using a selector switch in the enclosure.
