II. Technical Specifications
(1) Measurement Parameters
Speed Measurement: This device can accurately measure rotational speed, with a common measurement range covering intervals such as 0-150 revolutions per minute (RPM). The specific measurement range can be customized and adjusted according to actual application requirements. It has extremely high measurement accuracy, which can accurately reflect the actual speed of the equipment, providing reliable data reference for operators. In the scenario of monitoring the engine speed of a ship, DLQ144-PC-NB can accurately measure the real-time speed of the engine, helping operators keep abreast of the engine's operating status, ensuring that the engine runs in the optimal speed range, improving fuel efficiency, and reducing equipment wear.
Other Parameter Measurement (if applicable): In addition to speed measurement, some models of DLQ144-PC-NB may also have the function of measuring other parameters. For example, in some special applications, it can measure parameters such as rudder angle. For rudder angle measurement, its measurement range can usually cover the full stroke range of the ship's steering gear, and the measurement accuracy can reach ±1° or even higher, which is crucial for the precise control of the ship. By accurately measuring the rudder angle, the driver can grasp the ship's steering state in real-time, ensuring that the ship sails according to the predetermined route and improving navigation safety.
(2) Electrical Characteristics
Input Characteristics: It has various types of input signals, with common input signals including 10-0-10V voltage signals. This voltage input range is compatible with a variety of sensors or signal sources, facilitating users to configure flexibly according to actual needs. For example, when connected to the speed sensor of a ship's engine, the voltage signal output by the sensor can be directly connected to the input port of DLQ144-PC-NB, and the device can quickly and accurately process and convert the input signal, and then display the corresponding speed value. In addition, the input load capacity of the device is 9kΩ, which means it can adapt to signal sources with different impedances to a certain extent, ensuring the stability and accuracy of signal transmission, and avoiding signal distortion or measurement errors caused by mismatched input loads.
Power Requirements: In terms of power supply, DLQ144-PC-NB supports 24V AC/DC power input. This wide voltage input range design enables it to adapt to the power supply conditions of different ships or industrial sites. The device can work stably regardless of whether the system uses AC or DC power. At the same time, its power supply design has good anti-voltage fluctuation ability. Even if the power supply voltage fluctuates within a certain range, the device can still maintain normal operation without affecting measurement accuracy or causing equipment damage due to voltage fluctuations.
(3) Display and Adjustment
Display Function: DLQ144-PC-NB is equipped with a clear and readable display device, which can intuitively show the measured parameter values. Its display mode is usually digital display, with large and clear digits. In the ship's cockpit or industrial control room, operators can easily read data under various light conditions. Some high-end models may also have a backlight display function. In dimly lit environments, the backlight display can automatically turn on, ensuring clear visibility of data and facilitating operators to monitor and operate the equipment at night or under low light conditions.
Adjustment Function: The device has certain adjustment functions, for example, its adjustment range can reach ±10%. This adjustment function is of great significance in practical applications. When the device is installed on different types of ships or industrial equipment, due to possible differences in the operating characteristics and measurement requirements of the equipment, through the adjustment function, users can fine-tune the display range or sensitivity of the measurement parameters according to the actual situation, so that the device can better adapt to different working scenarios and provide measurement results more in line with actual needs.
(4) Physical Characteristics
Size and Installation: The panel size of the device is 144mm, adopting a standard panel mounting method. This installation method is simple and convenient. Users only need to embed the device into the pre-designed mounting hole of the instrument panel in accordance with standard installation specifications, and then fix it with supporting installation accessories. During ship construction or industrial control system upgrading and transformation, this standardized installation method can greatly improve the installation efficiency of the device and reduce installation time and cost. At the same time, the 144mm panel size, on the premise of ensuring the complete functionality of the device, also takes into account the reasonable use of the instrument panel space, and will not occupy too much space on the instrument panel due to the large size of the device, affecting the installation and layout of other equipment.
Weight: The weight of DLQ144-PC-NB is approximately 630g. The relatively light weight makes it more convenient during installation and transportation. During the installation of ship equipment, the light weight is convenient for installers to operate, reducing the labor intensity during installation. At the same time, when the equipment needs maintenance or replacement, the light weight also makes the disassembly and handling of the equipment easier, improving the efficiency of equipment maintenance.
III. Application Scenarios
(1) Marine Field
Engine Monitoring: In the ship's engine system, DLQ144-PC-NB plays a crucial role. It provides operators with accurate engine operating data by real-time monitoring the engine speed. Operators can adjust the engine's throttle opening in a timely manner according to this data, keeping the engine in the best working condition. When the ship is in different navigation conditions, such as acceleration, deceleration, and cruising, the engine's speed requirements will change. DLQ144-PC-NB can track the speed changes in real-time and feed back the data to the operators, helping them make correct decisions, ensuring the stable operation of the engine, and improving the ship's navigation performance and fuel economy.
Steering Gear Control Assistance: For the ship's steering gear system, DLQ144-PC-NB can be used to measure the rudder angle. Accurate rudder angle measurement is crucial for the ship's steering control. By observing the rudder angle value displayed by DLQ144-PC-NB, the driver can precisely control the ship's steering, ensuring that the ship sails according to the predetermined route. In complex operations such as ship entry and exit from ports and obstacle avoidance, accurate rudder angle measurement and display can help the driver control the ship more accurately, avoid collision accidents, and improve the safety of ship navigation.
Monitoring of Other Auxiliary Equipment: On a ship, in addition to the engine and steering gear, there are many other auxiliary equipment, such as pumps and fans. DLQ144-PC-NB can be used to monitor the speed of these auxiliary equipment, helping operators keep abreast of the equipment's operating status. When the speed of the auxiliary equipment is abnormal, operators can promptly detect the problem through DLQ144-PC-NB and take corresponding measures to deal with it, avoiding the impact of equipment failure on the normal operation of the ship.
(2) Industrial Field
Motor Speed Monitoring: In industrial production, motors are widely used as power equipment. DLQ144-PC-NB can be used to monitor the speed of motors to ensure that they run within the normal speed range. For some production processes with strict speed requirements, such as the textile and papermaking industries, the stability of motor speed directly affects product quality. By using DLQ144-PC-NB to monitor motor speed in real-time, production personnel can adjust the motor's operating parameters in a timely manner, ensuring the stability of the production process and the consistency of product quality.
Monitoring of Mechanical Equipment Operating Status: For various industrial mechanical equipment, such as machine tools and compressors, DLQ144-PC-NB can reflect the overall operating status of the equipment by measuring the speed of key components of the equipment. When equipment fails, it is often accompanied by abnormal changes in speed. Through the analysis of the monitoring data of DLQ144-PC-NB, maintenance personnel can predict equipment failures in advance, carry out maintenance and repair in a timely manner, reduce equipment downtime, and improve production efficiency.
