The DEH Rotation Speed Probe MP-988 adopts the detection method of magnetoresistive elements and magnetic gears. It has the advantages of flexible detection distance, wide operating temperature range, good stability, and easy installation. It is widely used in speed monitoring of various rotating equipment such as steam turbines and generators.

Core technology interpretation

1. Combination of magnetoresistive elements and magnetic gears

The DEH Rotation Speed Probe MP-988 adopts the detection method of magnetoresistive elements and magnetic gears to achieve high-precision measurement of speed. Magnetoresistive elements have the characteristics of high sensitivity and fast response speed, while magnetic gears ensure the stability of detection. The combination of the two makes MP-988 have a higher performance advantage in the field of speed measurement.

2. Flexible detection distance

The detection distance of MP-988 depends on the module of the gear and can be adjusted according to actual needs. This feature enables MP-988 to adapt to gears of different sizes and has a wide range of applicability.

3. Wide operating temperature range

The operating temperature range of MP-988 is -10℃~+70℃, which meets the use requirements in various harsh environments.

Product Features

1. Detectable at nearly 0r/min: DEH Rotation Speed Probe MP-988 has extremely high detection sensitivity and can accurately capture the speed signal even at low speed conditions close to 0r/min.

2. Non-contact detection and good stability: Due to the non-contact detection method, MP-988 is not affected by wear, vibration, etc. during operation and has high stability.

3. Small and light, easy to install: MP-988 is small in size, light in weight, and has a simple installation process, which greatly reduces the difficulty of on-site construction.

4. Flexible installation position: As long as the detection gear can be installed on the object to be measured, the installation position of MP-988 is irrelevant, which provides great convenience for users.

Take a 1000MW steam turbine as an example; it is generally necessary to install 3 speed probes MP-988. These probes are M19mm*1.25mm in size and have no intermediate joints, which ensures the transmission efficiency of the signal. During the installation process, it should be noted that MP-988 has an inverted triangle mark on the two symmetrical planes, and the probe positioning depends on this mark. The triangle should be aligned with the center line of the gear and parallel to the gear teeth. There is no order between the two surfaces.

When installing the DEH Rotation Speed Probe MP-988, leave a gap of 0.8mm~1.0mm. If the key point is that the gap and direction are in conflict, pay attention to the direction first, and consider the gap later. In addition, MP-988 has a high degree of integration and does not require a preamplifier, which further improves the reliability of the product.
