Widely applicable in industrial and laboratory scenarios, it can be used in conjunction with electronic evaluation equipment such as epro RMS 700 or MMS 6000 speed monitoring systems to complete measurement, monitoring, monitoring or control tasks such as rotation direction detection, slip, gear ratio, backlash, etc. It can also be used to issue proximity signals, alarms, switch control, count mechanical events, etc. Due to its high resolution, fast response internal electronic components, and sharp output pulse edges, it can measure extremely high and low speeds with high precision.

Working principle and structure

Working principle: The sensor head is a differential sensor composed of two series connected magnetic sensitive semiconductor resistors, installed above a small permanent magnet. The two resistors in the electronic part of the sensor form a Wheatstone bridge, which controls the subsequent DC switching amplifier with fast push-pull short-circuit protection output. When the trigger mark made of soft iron or steel approaches the sensor vertically, it interferes with the internal magnetic field, causing the bridge to become unbalanced and the output voltage to switch to a high level; When the trigger marker passes by, the bridge becomes unbalanced in reverse and the output signal returns to a low level. The output pulse has sharp edges and can be capacitively coupled with subsequent electronic devices even at the lowest triggering frequency.

Construction: High quality electronic circuits are packaged in a sturdy stainless steel casing, and the connecting cables are insulated with polytetrafluoroethylene. If necessary, flexible metal tubes can be added for protection.

Sensor Overview

The PR 9350/.. Series linear displacement sensor is an inductive sensor mainly used to measure static and dynamic displacement, and can also be combined with carrier frequency measurement bridge to measure physical quantities that can be converted into linear motion (such as tension, pressure, material thickness, etc.). It has the characteristics of high resolution across the entire range, small hysteresis, sturdy structure, low control target force, wide measurement range (± 12 to ± 150 mm), high accuracy, and sealed packaging.

Working principle

The differential coil of the sensor consists of a coil holder with two windings and a solenoid plunger with a ferromagnetic core that moves within the coil. When the tracing needle is precisely located in the middle of the coil, the impedance of the two windings is the same; When the probe with a ferromagnetic core moves from the middle position towards one end of the sensor, the impedance of one winding will increase, while the impedance of the other winding will decrease. By using resistors to supplement the winding into a Wheatstone bridge and providing a carrier frequency to the bridge, the measured output of the bridge will obtain a voltage proportional to the displacement of the stylus. The tracing needle can move freely and comes with an M3 threaded rod for mechanical adaptation to the measurement target. There is a 3-pole Cannon socket on the top of the housing for electrical connection.

Precautions

When installing sensors, it is necessary to ensure that the distance between the sensor and the object being measured is within the effective measurement range, in order to avoid affecting the measurement accuracy due to the distance being too close or too far.

The length and model of the extension cable should be selected according to the requirements of the sensor and preamplifier to ensure stable signal transmission.

Regular calibration and maintenance are required during system operation to ensure the accuracy and reliability of measurement data.

Sensor Overview

The PR 9266/.. And PR 9268/.. Series electric absolute vibration sensors are designed specifically for measuring the absolute vibration of machines and are part of the MMS 6000 and MMS 3000 rotating machinery monitoring systems. Its working temperature range can reach 200 ° C, using seismic function principle, easy installation, high sensitivity, sturdy structure suitable for industrial applications, with splash proof characteristics, protection level of IP 55 or IP 65, with two frequency ranges of 10 Hz to 1000 Hz and 4 Hz to 1000 Hz. When used in conjunction with safety barriers (Zone 1), the safety level is EEx ib II B/II C.

Application scenarios

The absolute vibration can be measured in frequency ranges of 10… 1000Hz and 4… 1000Hz, with vibration amplitudes of up to 2mm and 3mm (peak to peak), respectively. It can provide an electrical signal proportional to the vibration velocity. Suitable for various types of turbomachinery, fans, compressors, gearboxes, pumps, coal mills, and other machines. Among them, PR 9268/60 and PR 9268/70 are particularly suitable for high-temperature environments, such as gas turbine applications, and also include electrical adaptation, which can replace the original AEG Kanis Group’s MMG 033 and MMG 1033 absolute vibration sensors, and provide three different sensor sensitivities according to the type of measurement amplifier.

Functional Principles and Design

Measurement element: composed of seismic mass blocks with coils, suspended on diaphragm springs, moving in the circular gap of permanent magnets, and guided by diaphragm springs in the longitudinal direction (measurement direction) of the measurement element.

Working mode: The sensor operates above the resonance frequency (different models have resonance frequencies between 4 and 13 Hz), while the seismic mass remains stationary. Due to the vibration of the sensor housing, an electrical signal proportional to the vibration velocity is generated.

Damping: The damping of the measuring element is achieved through a damping cylinder or external device, with a damping value of about 0.6 and good linear characteristics throughout the entire frequency range.

Special design: Measurements below the resonance frequency can be corrected by corresponding amplitude response; When the vibration amplitude is too high, the mechanical limiter will reduce the maximum amplitude of the seismic system; Each sensor is designed for a measurement direction (vertical or horizontal). The PR 9266/.. Series sensor has an additional lifting coil, which adjusts the center position of the seismic element by inputting a lifting current of up to 7mA into the coil; The PR 9268/.. Series sensors can directly input the boost current into the measurement coil, but this current must be separated from the measurement signal. The measurement amplifier of MMS 6000 supports the operation of absolute bearing vibration sensors and provides boost current.
