Product Description

The PR9376/010-011 is a speed sensor mainly used to measure the speed of rotating machinery. Here are some details about the PR9376/010-011 product:
Manufacturer: This sensor is made by Emerson or its EPRO subsidiary and is part of the PR9376 family.
Application: PR9376/010-011 is widely used in turbo-machinery such as steam engine, gas engine, turbine, compressor, fan, centrifuge to monitor and control the speed of these equipment.
Working principle: The sensor adopts the oscillator design formed by the turbine sensor and the preprocessor. When the sensor probe is close to the metal subject, the amplitude changes, and this change is converted into an electrical output, so that the speed is measured.
Technical specifications:
High resolution, low speed can also output waveform.
Measuring range: 0… 20kHz, suitable for different speed measurement requirements.
Measurement gap: ≤1.5mm, to ensure that the sensor and the measured object maintain a proper distance.
Sensor power supply: 8… 31.2Vdc with a stable supply voltage range.
Temperature range: -30℃… +100℃, to ensure that it can work properly in various environments.
Installation and configuration:
The PR9376/010-011 sensor is available in a variety of models and configurations to meet different measurement environments and requirements.
Sensors can be fitted with mounting threads or rectangular mounting flanges for easy mounting to mechanical equipment.
The measurement range also covers 1mm to 20mm to accommodate different sizes of the object being measured.
Cable length and order number can be selected according to specific needs.
Calibration and maintenance: Before leaving the factory, the sensor has been linearly calibrated using calibration materials, so the user does not need to calibrate again. The user only needs to adjust the air gap between the sensor and the measuring surface to get the desired signal from the output of the preprocessor.
Dynamic performance:
The sensitivity is 2 volts/mm (50.8 mV/ mil) and the maximum error is ±1.5%.
The long-term drift is less than 0.3% to ensure the stability of the measurement results.
The static range is 4 mm (0.157 in) to adapt to different measurement environments.

APPLICATION

The PR9376/010-011 speed sensor is mainly used to measure the speed of rotating machinery, and its application scenarios include but are not limited to the following:
Steam engine, gas engine, water turbine: These equipment need to monitor the speed in real time during operation to ensure that its operation is in a safe and stable range. The PR9376/010-011 sensor can provide accurate speed measurement data to help operators grasp the operating status of the equipment in time.
Compressors, fans, centrifuges and other turbo-machinery: these devices also need speed sensors to monitor their operating status. By measuring the rotational speed, you can determine whether the device is in normal working condition and whether maintenance or adjustment is required.
Power systems: In power systems, speed sensors also play an important role. For example, in the operation of the generator set, it is necessary to monitor its speed in real time to ensure the stability and reliability of the power output. The PR9376/010-011 sensor can provide high precision speed measurement data to meet the needs of power system speed monitoring.
In short, the PR9376/010-011 speed sensor is widely used in various scenarios where the speed of rotating machinery needs to be measured. Its features such as high resolution, wide measurement range, stable supply voltage and wide operating temperature range make it a reliable and practical speed measurement tool.
