Product Description
The Bentley 990 - 05 - 70 - 02 - 01 is a high - performance vibration transmitter that has been engineered to meet the demanding requirements of industrial applications. It is designed to provide accurate and reliable measurement of vibration levels in various types of machinery, playing a crucial role in ensuring the smooth operation, safety, and longevity of industrial equipment. This two - wire vibration transmitter is a product of advanced technology and precision manufacturing, offering a range of features that set it apart in the market.
The full - scale range of the Bentley 990 - 05 - 70 - 02 - 01 is 0 - 5 mils pp (0 - 125 µm pp). This measurement range is suitable for a wide variety of industrial machinery, allowing for the detection of even minor vibrations that could potentially lead to serious problems if left unaddressed. The ability to accurately measure such a range enables users to closely monitor the health of their equipment and take appropriate action at the right time.
With a frequency response of 5 Hz to 6,000 Hz + 0.3 dB, the transmitter can precisely detect vibrations across a broad spectrum of frequencies. This wide frequency range makes it applicable to different types of machinery, from slow - moving equipment to high - speed rotating machinery. For example, in a power generation plant, it can effectively monitor the vibrations of turbines that operate at high rotational speeds, as well as the vibrations of pumps and motors that may have lower - frequency vibrations associated with their operation.
Features
It is compatible with ungrounded, portable test equipment. However, when using grounded, ac - powered test equipment, signal isolation is required. This compatibility feature allows for flexibility in testing and calibration procedures. The transmitter is designed to work in harmony with proximity probes, such as the 3300 nsv proximity probe from GE Bently Nevada. The linear range starts at 0.25 mm (10 mils) from the target surface and extends up to 1.4 mm (55 mils). The incremental scale factor is 7.87 mv/µm (200 mv/mil) ± 6.5% typical, ensuring accurate conversion of vibration measurements into electrical signals.
Maintaining accuracy over a wide temperature range is a key feature of this vibration transmitter. It can operate within a temperature range of 0 °C to 70 °C (32 °F to 158 °F) while still providing reliable and accurate readings. This temperature stability is essential in industrial environments where the operating temperature of machinery and the surrounding environment can vary significantly. Whether in a hot and humid factory setting or a cooler industrial space, the Bentley 990 - 05 - 70 - 02 - 01 can continue to function optimally.
Product Overview
The transmitter requires a +12 to +35 VDC input at the transmitter terminal. This power supply range is common in industrial settings and allows for easy integration into existing power systems. The power - up inhibit circuit is an added advantage, as it eliminates signal errors due to line voltage transients. This ensures that the transmitter starts up smoothly and provides accurate readings from the moment it is powered on.For proper operation, the probe should be gapped between 0.5 and 1.75 mm (20 to 55 mils) from the target surface. This specific probe gap range is carefully designed to ensure full - scale operation and accurate vibration measurement. If the probe gap is not within this range, it can lead to inaccurate readings or improper functioning of the transmitter.The integrated proximitor sensor is a unique feature of this vibration transmitter. It eliminates the need for an external unit, simplifying the overall system setup. This integration not only reduces the complexity of the installation but also improves the reliability of the vibration measurement. With no external components to worry about, there are fewer points of failure, resulting in a more robust and stable vibration monitoring system.The Bentley 990 - 05 - 70 - 02 - 01 has dimensions of 100 × 74 × 53.3 mm and weighs 0.43 kg. Its compact size and relatively light weight make it easy to install in various locations, even in tight spaces where machinery may have limited room for additional components. This portability and ease of installation contribute to its widespread use in different industrial applications.The non - interacting zero and span potentiometers, which are located under the transmitter label, support loop adjustment. This feature allows for easy calibration and fine - tuning of the transmitter to ensure accurate readings. Whether it is compensating for changes in the machinery or adjusting for different operating conditions, the loop adjustment feature provides the flexibility needed to maintain optimal performance.
