Description
The DLQ144-PC-NB is a pitch indicator developed by DEIF, a company renowned for its high – quality contributions to the industrial control and marine automation sectors. This device is engineered to provide accurate and reliable pitch indication, playing a crucial role in various applications where precise monitoring of pitch – related parameters is essential.
Application Scenarios
In the shipping industry, a large – scale cargo ship was facing challenges in maintaining optimal navigation efficiency. The crew needed to precisely control the ship’s propeller pitch to adapt to different sea conditions and load requirements. Before installing the DLQ144 – PC – NB, the pitch adjustment was based on rough estimations, leading to increased fuel consumption and reduced speed. With the DLQ144 – PC – NB in place, it provided real – time and accurate pitch readings. The ship’s operators could now adjust the propeller pitch more precisely, resulting in a 15% reduction in fuel consumption during a six – month period. This not only saved costs but also increased the ship’s overall operational efficiency.

Technical Principles and Innovative Values
- Innovation Point 1: Precise Signal Processing
The DLQ144 – PC – NB utilizes advanced signal processing algorithms. It can accurately interpret the input voltage signals related to pitch and convert them into highly precise pitch readings. In a marine research vessel, compared to older – model pitch indicators, the DLQ144 – PC – NB reduced pitch measurement errors by 50%, providing more reliable data for scientific research operations.
- Innovation Point 2: Robust Design for Harsh Environments
Engineered with a robust construction, it can withstand the harsh conditions of marine and industrial environments. For example, in a coastal power plant where there is high humidity and salt – air exposure, the DLQ144 – PC – NB has shown excellent durability. Its protective housing and corrosion – resistant components ensure long – term reliable operation, with a failure rate 30% lower than similar products in the same environment.
- Innovation Point 3: User – Friendly Interface
The pitch indicator features a user – friendly interface. The clear and easy – to – read display, along with simple adjustment controls, makes it accessible to operators with different levels of technical expertise. In a training facility for ship operators, new trainees were able to quickly understand and use the DLQ144 – PC – NB within an hour of training, which was much faster compared to other complex pitch indication devices.
Application Cases and Industry Value
In a fishing fleet, the DEIF DLQ144 – PC – NB was installed on multiple fishing boats. Fishermen previously had difficulty adjusting the propeller pitch while navigating through different water currents and when hauling nets. After installing the DLQ144 – PC – NB, they could precisely control the pitch, which improved the boats’ maneuverability. The fishermen reported a 20% increase in the amount of catch per trip as they could now position the boats more accurately in fishing areas.
In a shipbuilding yard, the DLQ144 – PC – NB was incorporated into the design of new vessels. Shipbuilders found that it enhanced the overall quality of the ships’ control systems. The accurate pitch indication provided by the DLQ144 – PC – NB contributed to better – optimized engine performance and reduced wear and tear on the propellers. This led to a decrease in maintenance costs for the ship owners by approximately 18% over the first five years of operation.
