Yokogawa launches nine models of digital manometer

For measurement and long-term stability for pressure sensors in consumer goods and wearables, used in automotive and medical equipment, Yokogawa has developed the MT300 digital manometer. It is intended to meet the need for higher levels of precision pressure measurement for the development and calibration of these applications, with multiple models for gauge, absolute and differential pressures.

It is based on proprietary silicon based resonant sensor technology, and is claimed to offer the high levels of accuracy and stability required for use as an international calibration transfer standard.

The MT300 has an absolute accuracy of pressure measurement of 0.01 per cent with a guaranteed period of 12 months, says Yokogawa. It has an intuitive colour display and a battery-powered option, making it suitable for pressure-based applications, which ranges from ventilation extraction systems to vacuum packaging.

Four models of the MT300 are available for gauge pressure, covering 10 to 3,500kPa. The absolute pressure model has a range of 130kPa, while the three differential pressure models have ranges from 1kPa to 700kPa.

The instrument meets the needs of a wide range of applications, continues Yokogawa, from pressure leak testing in a vessel, to the airspeed measurement of hair dryers. Depending on the model selected, measurement intervals down to 50ms are achievable with the /F1 option, allowing the measurement of very rapid transient pressure variations such as in applications using a differential pressure flow transmitter.

Using the high resolution display (/R1 option), pressure measurements can be more accurately displayed and visualised. The increased resolution in calibration environments, reduces the uncertainty of the entire calibration process.

When multiple pressure variables need to be measured and recorded simultaneously, up to four MT300 units can be interconnected and synchronised to a personal computer via GP-IB, USB or Ethernet. This eliminates measurement variations due to fluctuating atmospheric conditions and simplifies the automation process.
