Pressure sensor or transducer for differential pressure and volume flow, with Modbus connection, with automatic zero point calibration PREMASGARD 7147-Modbus

Maintenance-free microprocessor-controlled PREMASGARD® 714x - Modbus (series) with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, connection piece for pressure hose (Ø 6 mm), with cable gland or M12 plug connector to DIN EN 61076-2-101, optionally with ⁄ without display, for measuring the differential pressure (max. ± 7000 Pa) in air. International system of units SI (default) is set to Imperial (via Modbus). Incl. connection set ASD-06 (2 m connection hose, two pressure connection nipples, screws).


The pressure sensor is used to measure positive, negative or differential pressures in clean air and gaseous media. It is used in clean room, medical and filter technology, in ventilation and air conditioning ducts, in spray booths, in commercial kitchens, for filter monitoring and level measurement or for controlling frequency converters. A pressure sensor with piezoresistive measuring element guarantees precise measurement results. The following parameters can be called up via Modbus: Differential pressure, volume flow.

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.
