PREMASGARD
Maintenance-free, microprocessor-controlled PREMASGARD
optionally with ⁄ without display, with cable gland or M12 connector according to DIN EN 61076-2-101, for measuring the differential pressure (max.
–7000...+7000 Pa) in air. Incl. connection set ASD-06 (2 m connecting hose, two pressure port nipples, screws). Type variant 724x T with connection
facility for external Pt1000 sensor (sensor element not included in the scope of delivery) for detecting the temperature (–50...+150°C).
The standard display can be changed from SI [Pa, m
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 measure-
ment or for triggering frequency converters. A pressure sensor with piezoresistive measuring element guarantees exact measurement results.
The following measured values can be accessed via the Modbus: Differential pressure, volume flow and 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 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.
