Maintenance-free microprocessor-controlled PREMASGARD® 814x - Modbus (Series) with
Modbus connection, in an impact-resistant plastic housing with quick-locking screws, optionally
with/ without display, with a plastic sinter filter (exchangeable), to exactly detect the relative
humidity (0…100% r.H.) and the temperature (–35...+80 °C) in ducts and to measure the
differential pressure (max. –7000...7000 Pa) in air. Incl. mounting flange and connection set
ASD-06 (2m connecting hose, two pressure port nipples, screws).
The pressure sensor is applied to measure positive, negative or differential pressure in clean air and gaseous media. It is used in the clean room, medical and filter technology, ventilation and air conditioning ducts, spray booths, large-scale catering facilities, for filter monitoring and level measurement or for triggering frequency converters.
A long-term stable, digital humidity and temperature sensor and a pressure sensor with piezoresistive measuring element guarantee exact measurement results. These measurands are used to internally calculate the following parameters that can be retrieved via Modbus: temperature [°C], relative humidity [% r. H.], dew point [°C], absolute humidity [g/m³], mixture ratio [g/ kg], enthalpy [kJ⁄ kg] (ignoring atmospheric air pressure), differential pressure [Pa], volume flow [m3/h], air density [kg/m3].
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.
Humidity: 0...100 % r. H.
Temperature: –35...+80 °C
