Manometers

Senseca instruments for pressure and airflow measurement, developed from Delta Ohm experience, include manometers, micromanometers, barometer-manometer-thermometers and datalogger versions for applications in HVAC, ventilation, heating, maintenance, laboratory work and industrial testing.

The range includes portable instruments for absolute, relative and differential pressure measurements, with the possibility of adding temperature measurement using Pt100, Pt1000 or type K thermocouple probes, depending on the instrument family selected. Models with LP471 module support the connection of TP704 and TP705 pressure probes, allowing the instrument to be adapted to the required measurement range and application type.

For low-pressure applications, micromanometers with internal sensor and 20 mbar full scale are available, suitable when small pressure differences must be measured with good sensitivity. The 200 mbar models cover a wider range of applications, while the 2000 mbar versions are intended for higher differential pressure measurements. The range also includes barometer-manometer-thermometers with integrated barometric sensor from 600…1100 mbar, useful when atmospheric pressure monitoring is also required.

For airflow velocity and flow rate measurements, micromanometers for Pitot tubes are available, designed for HVAC systems, ducts, air outlets and ventilation channels. Versions with 20 mbar full scale are suitable for air velocity measurements from 2 to 55 m/s, while 200 mbar models allow measurements up to 180 m/s. By entering the duct section area, the instrument can also calculate airflow rate.

The datalogger versions can store up to 36,000 samples, with data transfer via RS232C or USB. This function is useful when reading the instantaneous value is not sufficient and it is necessary to document pressure, temperature, velocity or flow rate trends over time. Through the menu it is possible to configure logging intervals, print settings and communication parameters.

REL, HOLD, Max, Min and Avg functions simplify daily field work, while the PEAK function, available with compatible external probes, allows pressure peaks to be detected. Depending on the model, IP66 or IP67 protection rating makes these instruments suitable for use in technical environments during maintenance operations, testing and field verification activities.

The choice of the most suitable manometer depends on the type of pressure to be measured, the required full scale, the presence or absence of an internal sensor, the need for data logging and the type of temperature measurement required.

S.A.M.A. Italia supplies Senseca manometers, micromanometers and barometer-manometer-thermometers (formerly Delta Ohm), complete with ACCREDIA calibration carried out directly in Senseca laboratories when предусмотрено for the selected configuration, ensuring reliable results, metrological traceability and compliance with applicable international standards.
