GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM OUTSIDE HUMIDITY TRANSMITTER HSOB SERIES PRODUCT DESCRIPTION The outside 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 12.7 mm (0.5”) diameter 304 S/S probe and is field replaceable. A 60 micron HDPE filter protects the sensor for contaminants and a sun and windshield for protection from the elements. A weatherproof enclosure that provides ease of installation is provided. An optional integrated temperature sensor is available. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The outside transmitter should be mounted on an outside North facing wall, under the eaves which will provide protection from direct sunlight and wind. The outside transmitter can be mounted directly to buildings wall face using the provided mounting holes. There is a 0.86” hole for conduit connection of the back of the enclosure.
