Relative humidity and temperature sensor KFTF-Modbus-T3

absoluteresistancedew-point

Calibratable duct humidity and temperature sensor HYGRASGARD® KFTF - Modbus - T3 (± 2.0%) or KFTF - 20 - Modbus - T3 (± 1.8%), with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, optionally with/ without display, with a plastic sinter filter (exchangeable), incl. mounting flange, to exactly detect the relative humidity (0…100% RH) and the temperature (–35...+80 °C) and to detect various parameters in humidity measurement. International system of units SI (default) can be switched to Imperial (via Modbus). The duct sensor is applied in a non-aggressive, dust-free environment and is suitable for installation in ceilings, ducts and devices. It is used in the refrigeration, air conditioning and clean room technology, engineering rooms, hotels and conference facilities. A long-term stable, digital humidity and temperature sensor guarantee exact measurement results. These measurands are used to internally calculate the following parameters that can be retrieved via Modbus: relative humidity, absolute humidity, mixture ratio, dew point, enthalpy (ignoring atmospheric air pressure) and ambient temperature. Innovative Modbus sensor with galvanically separated RS485-Modbus-interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in curent-free state, internal LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated; with customised programming in the 7-segment and dot-matrix range). The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
