Carbon Dioxide Transmitter aids on-demand ventilation.
To help prevent energy losses from over ventilation while also maintaining indoor air quality (IAQ), Series CDX CO2 sensor employs logic algorithm that eliminates need for manual calibration in applications where indoor CO2 level drops to outside levels during unoccupied periods. Sensing range is- 0–2,000 PPM, accuracy is- -

Non-Indicating 4-20 mA Transmitter can be wall or meter mounted.
Compatible- with Series EFS2, IEFS, PDWS, TBS, and FLMG, Series BAT (Blind Analog Transmitter) takes pulse frequency output from flowmeter and converts it into continuous 4–20 mA analog output signal. Frequency for flowmeter output signal can be adjusted using 4 rotary switches on back, and MCU automatically scales all other values accordingly. Also, MCU can average inputs for more stable...

Air Quality Transmitters measure CO2, RH, and temperature.
Combining CO2, RH, and temperature in one device, Series CDTR minimizes number of sensors mounted on wall or in duct. Transmitters use single-beam, dual-wavelength NDIR sensor to automatically correct measurement in both occupied and unoccupied buildings against light source aging effects. Universal outputs for both carbon dioxide and relative humidity allow users to select transmitter output to...

Volume Booster increases valve stroke speed.
Available in aluminum or stainless steel, Series VB Volume Booster allows for increase in valve stroke speed by providing large air flow volume to actuator. Booster receives positioner's signal output and supplies proper air pressure to actuator to reduce response and adjustment time. Reacting to slightest changes in supply pressure, this one to one signal to output relay has max supply pressure...
