combined-amplifier transmitter necessary to achieve the required ERP with a low-gain antenna. With the choices narrowed a bit, we still have a fairly wide range of choices for antenna gain and transmitter power output (TPO) to achieve the required ERP. It is at this point that other factors come into consideration. 2.1 Economic Considerations
measurements in one transmitter reduces both labor and material costs by only having to install one CDTV-VOC unit, instead of separate CO2 and VOC transmitters. SPECIFICATIONS Range CO2: 0 to 2000 or 0 to 5000 ppm (depending on model); VOC: 0 to 2000 ppm CO2 equivalent. Accuracy CO2: ±40 ppm +3% of reading.
The transmitter power transformer is a Stancor P4004 (175 ma DC rating) rather than the larger 200 ma rated Triad R-121-A. The P4004 was an old design in 1962 since it appears as XP-4004 in a 1937 Stancor catalog (for $8.50)1. Filter capacitors are the unusual 16 µF, 700Get Price

VOH VOC high output range Sets the VOC level for the highest output (10 mA or 5 V, 20 mA or 10 V). When VOH is set above VOL, the transmitter is direct acting and the output will increase with an increase in VOC level. When VOH is below VOL, the transmitter is reverse acting and the output will increase with a decrease in VOC level.
