Yokogawa Digital Manometer MT300

The MT300 delivers high speed, high resolution, and synchronous measurements for high measurement accuracy and long term stability. It offers various functions for field device calibration, including 24 VDC transmitter output, built-in communication resistance, and Li-ion battery operation. The D/A output makes it easy to output data to a recorder or other instrument, and external I/O terminals allow users to output control signals.

Engineered with Yokogawa's silicon-based resonant sensor, the MT300 achieves:

High precision measurements

High resolution display (When /R1 is selected.)

By using a high resolution display, pressure measurements can be more accurately displayed and visualized. In addition, the increased resolution, especially in calibration environments, reduces the uncertainty of the entire calibration process.

High resolution display

High speed measurement (When /F1 is selected.)

Rapid pressure changes and transient responses requires high speed and reliable measurements. Depending on the application, you can choose your measurement speeds from three different modes, normal, medium or high speed.

Synchronous measurement

Using the synchronization features, you can collect data and display measurements from multiple units. Measurements can be captured and correlated at high speed with high accuracy and confidence.

Application:
In the performance testing of vacuum cleaners, the suctionforce is calculated from the amount of suction-air in the pressure equalizing container and the degree of vacuum. The amount of intake-air can be obtained by measuring the differential pressure via a pitot tube, and the degree of vacuum can be obtained by measuring the absolute pressure. With the /F1 option, the dynamic characteristics can be captured at high speed, with accurate results, by synchronously measuring these two values from two MT300s.

Synchronous measurement

Support for efficient works

Leak test feature

The Leak-test feature can be used to measure pressure change or leak rate within the measurement period. It can be used to check the tightness or integrity of a pressure measurement system.

Leak test

Start: Pressure value and time when started
Stop: Pressure value and time when stopped
Time: Measurement time
Delta: Difference of pressure value between started and stopped
Rate: Deffence of pressure value per minute
Leak test

Scaling

The scaling function can be used to assign customer specific coefficients to the measured values. Depending on the application, you can display your own conversion value. Scaling coefficient A and offset B are determined according to the following equation. Set the scale values for the upper and lower span limits.

Scaling

※ If you change the unit, set scaling coefficient A and offset B again.

Statistical processing

You can apply statistical processing to the data acquired. Find and display the maximum value, minimum value, average value, and standard deviation for the measured data. When error data is detected, the number of error data within the measurement range can be recorded and displayed.

統計処理

Max:Maximum value AVG:Average value ERR:Number of error data
Min:Minimum value σ:Standard deviation  

Support for linkage with external devices

D/A output (When /DA is selected)

The Digital-to-Analog (D/A) option, makes it easy to output measured pressure values to an external terminal going to a measurement system or a recorder. The output update interval can be set to 250 μs in combination with the /F1 option (in medium-speed/high-speed modes).

Comparator output

Using external I/O terminals, you can output control signals, based on set upper and lower limits and judgement criteria’s on measured values. These features allow automation of production and/or inspection lines for pressure-related products.

Interfaces

Communication Interfaces such as GPIB, USB (type-B), and ETHERNET are available as standard features. Communication commands are compatible*1*2 with existing models*3, making it easy to expand or update your existing measurement system.
*1: Some command cannot be used.
*2: Compatible commands cannot be used when -G07, -G08, -A05, -A06 are selected.
*3: MT210/MT210F/MT220

Support for field device calibration and maintenance works

Calibration involves inputting the same pressure level to both a calibrator and a transmitter and comparing the transmitter output with a value measured by the calibrator. The MT300 come with the functions you need for such calibration or maintenance work in the field.

Above functions can be available when /DM is selected.

Above function can be available when /EB is selected or add them as accessory after ordered.

High performance and reliability

Yokogawa’s proprietary and self-developed silicon based resonant sensor enables high accuracy, high resolution, and high stability pressure measurement system.

Yokogawa’s proprietary silicon resonant sensor has excellent characteristics that satisfy the conditions required for “accuracy measurement”, such as stability, reproducibility, sensitivity, and temperature characteristics.

High sensitivity and resolution and superior long term stability
The vibrators are in a vacuum. This reduces the dispersion of vibration energy. Combined with the superior flexibility of silicon single crystal, this makes it possible to obtain a high Quality factor.

Extremely low temperature dependency
Two vibrators are used, and pressure is derived from the difference between the two unique oscillation counts. With this operating structure, it is possible to cancel out external environment influences such as ambient temperature. In addition, the vibrators are in a vacuum, so they are not affected by humidity.

Extremely low temperature dependency

A vibrator, formed using semiconductor process technology on a silicon wafer, is driven by a permanent magnet. When pressure is applied to the silicon diaphragm, the vibrator is distorted, causing the resonant frequency to change.

International Comparison
The Yokogawa’s pressure sensor and the MT series are adopted as a Transfer Standard for many CC-level and the regional-level (for example APMP) international comparisons of pressure standards based on the enhanced performance of digital pressure gauges and the evaluation result of long term stability.

* Transfer Standard:
A standard used as a transfer equipment to compare standards.
