GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM DUCT HUMIDITY TRANSMITTER HSDT SERIES CABLE GLAND FITTING THREAD ADAPTER 1/2” NPT TO M16 PRODUCT DESCRIPTION The duct humidity transmitter uses a highly accurate and reliable Thermoset Polymer based capacitance humidity sensor and state-of- the-art digital linearization and temperature compensated circuitry to monitor humidity levels. The sensor is encapsulated in a 230 mm (9”) long by 12.7 mm (0.5”) diameter 304 S/S probe and is field replaceable. A 60 micron HDPE filter protects the sensor for contaminants. An optional integrated temperature sensor is available. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The duct type probes are installed through a hole in the side of the duct to monitor a single point humidity within the duct. Install the probe in a straight section of duct at a suitable distance downstream from any heating, cooling or humidification devices. Mounting tabs on the outside of the enclosure for ease of installation. A terminal block connection is provided. for connection to the Building Automation System.
