Surface-mounted humidity and temperature sensors HYGRASGARD® AFTF-Modbus-T3 LCD

Calibratable outdoor humidity and temperature sensor HYGRASGARD® AFTF - Modbus - T3, with Modbus connection, in impact-resistant plastic housing with quick-locking screws, optionally with ⁄ without display, with plastic sintered filter (replaceable), for precise detection
relative humidity (0...100 % RH) and temperature (-35...+80 °C) as well as for determining various humidity measurement parameters. International unit system SI (default) is set to Imperial (via Modbus).
The surface-mounted sensor is used in non-aggressive, dust-free environments. It is used in refrigeration, air conditioning and clean room technology, technical rooms, hotels and conference facilities.

A long-term stable, digital humidity and temperature sensor guarantees exact measurement results.
The following parameters are calculated internally from these measured variables and can be called up via the Modbus: relative humidity, absolute humidity, mixing ratio, dew point temperature, enthalpy (disregarding atmospheric pressure) and ambient temperature.

Innovative Modbus sensor with galvanically isolated RS485 Modbus interface, switchable bus terminating resistor, DIP switch for setting the bus parameters and bus address in de-energized state, internal LEDs for telegram status display,
two separate push-in terminals and large three-line display (illuminated, individually programmable in the 7-segment range and dot-matrix range). The sensor is calibrated at the factory; fine adjustment by a specialist is possible depending on the environment.
