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
• integral passive temperature outputs reduce number of devices mounted in the space
• service display tool available for models without an integral led
• optional integral display and relay output

application:

• demand control ventilation in schools, office buildings, hospitals, and other indoor environments
• leed certification

technical specification:

• range:co2: 0 to 2000 or 0 to 5000 ppm (depending on model); temperature: 32 to 122f (0 to 50c).
• accuracy:co2: 40 ppm 3% of reading; temperature: 1 c @ 25.

Over a dozen stocked rang es are available from 0-3 in. w.c. to 0-100 psid or choose metric units in rang es from 0-0.75 kPa to 0-690 kPa. Circuit design enables use in 2-wire current loops.

Specification:

• Service : Air and non-combustible, compatible gases.
• Thermal Effect : 0.025% F.S./F (0.045% F.S./C).
• Zero and Span Adjustments : Accessible potentiometers.
• Electrical Connections : Terminal block.
• Process Connections : Barbed for 1/8" (3.18 mm) I.D. tubing.
• Enclosure Rating : Face designed to meet NEMA 4 (IP66).

Installation:

• Location: Select a location where the temperature of the unit will be between 20F and 120F. Distance from the receiver is limited only by total loop resistance. See Electrical Connections. The tubing feeding pressure to the instrument can be run practically any length required but long lengths will increase response time slightly. Mount the instrument in a location that will not be subject to excessive temperature, shock or vibration. All models are designed for mounting in an enclosed panel.
• Select the mounting position for the instrument on the panel. Prepare the panel by cutting and debarring the required opening. Refer to Figure A.
• From the front panel, slide the instrument through the cutout. The housing gasket should be against the housing flange before installing. From the rear of the panel slide the mounting collar over the housing. Hold the housing with one hand and using the other hand, push the collar evenly against the panel until the springs are com-pressed. The ratchets will hold the mounting collar and housing in place.

particulate transmitter

series pmt2 particulate transmitter

digital damping, non-stick probe, for broken bag detection

the series pmt2 particulate transmitter is designed to measure particulate emission levels from dust collector discharge. Using dc coupled electrostatic induction sensing technology, the transmitter monitors a pa current that is generated as particulate passes near the probe; a 4 to 20 ma signal will vary based on the particulate level. The pmt2 offers 6 sensitivity ranges allowing the user to choose the range that will best fit the application. The range and test selector switch can also be set to output a 4 ma or 20 ma signal to assist with set up or trouble shooting. Averaging time setting can be used to dampen the signal if desired.

relative humidity and temperature transmitter

model 657-1 relative humidity/temperature transmitter

dual channel design for simultaneous 4-20 ma output signals

the series 657 transmitters provide two 4 to 20 ma channels to produce separate output signals for both relative humidity and temperature. These devices deliver 2% accuracy for humidity and 1f for temperature measurements. Stainless steel probe can be easily mounted to most ductwork using either of the two optional kits below.
