RPFTF-20-MODBUS-T3

HYGRASGARD® RPFTF-20-MODBUS-T3

Item No. 1201-6246-1000-001
EAN 4 251325 618050

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 a stainless steel pendulum and a plastic sinter filter (exchangeable).

The sensor is used to detect various parameters in humidity measurement. It measures the relative humidity (0...100% r.H.) and the temperature (– 35...+80 °C) of the ambient air. These measurands are used to internally calculate the following parameters that can be retrieved via Modbus: relative humidity [% r. H.], absolute humidity [g/m³], mixture ratio [g/ kg], dew point temperature [°C], enthalpy [kJ⁄ kg] (ignoring atmospheric air pressure) and ambient temperature [°C]. A long-term stable, digital sensor guarantees exact measurement results.

The pendulum 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.

Innovative Modbus sensor with galvanically separated RS485-Modbus-interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in current-free state, 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. TECHNICAL DATA
