MT300 digital manometer for pressure measurement applications

Digital manometer for the high accuracy measurement of absolute or differential pressures.

The adoption of pressure sensors in consumer goods and wearables, and their increasing use in industries such as automotive and medical, has led to the need for higher levels of precision pressure measurement for their development and calibration. The new Yokogawa MT300 satisfies the high accuracy measurement and long-term stability requirements of these advanced applications, with multiple models for gauge, absolute and differential pressures.

The MT300 uses silicon based resonant sensor technology, offering the high levels of accuracy and stability required for use as an international calibration transfer standard. It has an absolute accuracy of pressure measurement of 0.01%.

Four models of the MT300 are available for gauge pressure, covering the ranges from 10 kPa to 3500 kPa. The absolute pressure model has a range of 130 kPa, while the three differential pressure models have ranges from 1 kPa to 700 kPa.

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

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.
