GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM FLEX-DUCT AVERAGE TEMPERATURE TRANSMITTER TXDF SERIES PRODUCT DESCRIPTION The flexible, multi-point duct averaging mounted temperature transmitter is available with a selection of platinum RTD sensors and a transmitter that provides a high accuracy signal with excellent long term stability, low hysteresis and fast response. They are available with various scaled ranges. The sensing cable is constructed to provide excellent heat transfer, fast response time, and is available in several lengths and quantity of sensing elements. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The flex-duct average probes are installed through a hole in the side of the duct to monitor an average temperature within the duct. Select a probe length that allows for criss-crossing the duct multiple times. Install the probes in a straight section of duct at a suitable distance downstream from any heating, cooling, or humidification devices. The cable probe needs to be fastened onto hangers using tube clamps or wire ties and should be secured every 100 cm or 3’ maximum to prevent movement of the wire and prevent wear. If sensor is to be used in high velocity or vibration environment use of rigid style duct probe is recommended. The enclosure provides mounting tabs for ease of installation. NOTE: This product is factory calibrated and any field adjustment will void the warranty.
