FAQ

Precision pressure measuring instruments

Who is Mensor and what do they do?

Mensor was founded in 1969 in Houston, Texas, and has been dedicated to the design and manufacture of the finest high-accuracy measurement, calibration and control instruments and test systems for pressure available. In 1978, Mensor relocated to San Marcos, Texas. From the first Mensor quartz manometer produced for the aviation industry in 1970 to the advanced computer-controlled pressure calibration systems of today, Mensor's name has become synonymous with reliability and innovation in the field of precision pressure measurement, control and calibration.


Can a 3-wire transmitter also work in a 2-wire configuration?

No.

Can each pressure transmitter measure any medium?

No, the materials stated in the data sheet are to be checked by the customer for resistance.

Can the connector be altered?

The electrical connection cannot be altered.

Can you switch between 4 ... 20 mA and 0 ... 10 V?

No, the output signal is defined in the order and cannot be changed.

What causes zero point drift?

Through the ageing of the electrical components, through temperature and load cycling.

What solutions are there against pressure spikes?

For this, we recommend a process connection with a reduced pressure port of 0.6 mm or 0.3 mm.

Will a pressure transmitter also work without a power supply?

No.

Will the pressure transmitter still work properly when the supply voltage is slightly below the minimum specified level?

Up to a certain pressure, the pressure transmitter will still provide a correct output signal. If the pressure increases beyond this point, however, the output signal will remain at the same value, since the power supply is not sufficient to drive the output fully.

What is the overpressure limit?

Pressures up to the overpressure limit will not cause any permanent damage to the measuring instrument, however, the error limits specified in the data sheet could be exceeded.

At what pressure could the pressure measuring instrument be destroyed?

Pressure values above the overpressure limit can lead to irreversible damage of the measuring instrument. It does not matter whether this pressure is present constantly or only for a short period of time. In either case, the complete destruction of the parts exposed to the pressure and the sudden escape of the pressure medium can be expected.
