HYGRASGARD® RPFTF-20-wModbus

Calibratable room pendulum humidity and temperature sensor HYGRASGARD® RPFTF - Modbus - T3 (± 2.0 %) or RPFTF - 20 - Modbus - T3 (± 1.8 %), with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, optionally with ⁄ without display, cable sensor with stainless steel pendulum and plastic sintered filter (replaceable), for precise measurement of 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 pendulum sensor is used in non-aggressive, dust-free environments and is suitable for ceiling and duct mounting as well as for device installation. It is used in refrigeration, air conditioning and clean room technology, technical rooms, hotels and conference facilities.

Stable over the long term, 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.
