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 level of pressure can tear a diaphragm?

The respective burst pressure. This is listed in the data sheet for each product.


What solutions are there against pressure spikes?

For this, we recommend a process connection with a 0.6 mm, or better a 0.3 mm, spark-eroded channel.

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?

Example: a pressure transmitter is specified with a minimum power supply of DC 10 V. The customer, however, has a system with only DC 9 V available.
