Introduction

In the field of industrial liquid level measurement, WIDE rigid stem insertion type level transmitters have become the preferred choice for many application scenarios thanks to their outstanding performance. This article will start from the technical features of product series such as LDUCC, PLUS, and CP210, and provide an in-depth analysis of the suitable application scenarios of rigid stem insertion type level transmitters in fields such as chemical processing and water treatment, helping commercial evaluation personnel quickly grasp the key points of model selection and solve technical confusion in procurement decisions.

1. Core advantages of rigid stem insertion type level transmitters

Rigid stem insertion type level transmitters adopt a stainless steel design and feature corrosion resistance and high pressure resistance, making them especially suitable for harsh industrial environments. WIDE series products perform outstandingly in terms of accuracy and stability, with measurement error controlled within ±0.2%FS, far better than industry standards. In addition, the LDUCC and PLUS series are also equipped with temperature compensation functions to ensure stable output within a wide temperature range of -40℃~85℃.

Compared with traditional float type level gauges, the rigid stem insertion design reduces mechanical moving parts and lowers the failure rate. CP210 and BOS-H208-K series products further adopt unique sealing technology, with a protection rating reaching IP68, allowing them to be fully immersed in liquid for long-term operation.

1.1 Material and structural features

The main body of stainless steel level sensors is usually made of 316L stainless steel, a material with excellent corrosion resistance, especially suitable for industries such as chemical processing and pharmaceuticals. The OM133T and DH709 series also provide Hastelloy options to meet the needs of more demanding corrosive environments.

The rigid stem structure design makes installation more convenient, requiring only flange or threaded connection for fixation. PT311L3 and YKKT-1C series products adopt a modular design, and during maintenance only the sensor part needs to be replaced, greatly reducing usage costs.

2. Analysis of typical application scenarios

In chemical production, WIDE rigid stem insertion type level transmitters are widely used for liquid level monitoring of various reaction kettles and storage tanks. Their corrosion-resistant characteristics enable them to accurately measure highly corrosive media such as acids and alkalis. The DB502 series products are specially added with an explosion-proof design and comply with ATEX certification, making them suitable for flammable and explosive environments.

The water treatment field is another important application scenario. PLUS series products are equipped with a self-cleaning function, which can effectively prevent impurities in wastewater from adhering, ensuring long-term stable operation. In municipal water supply and drainage systems, the large range design of the CP210 series (0-20m) perfectly meets the measurement needs of deep wells and water tanks.

2.1 Industry-specific solutions

The food and beverage industry has strict requirements for hygiene grade. The LDUCC series adopts food-grade stainless steel and hygienic flange connections, fully complying with 3A certification standards. The BOS-H208-K series, on the other hand, is specially designed for high-temperature media and can withstand liquid temperatures up to 150℃, making it an ideal choice for boilers and heat exchange systems.

In the field of petroleum storage and transportation, the OM133T series is equipped with lightning protection circuits to effectively cope with harsh outdoor environments. Its split-type design facilitates remote monitoring in hazardous areas, greatly improving safety.

3. Guide to key selection parameters

When selecting rigid stem insertion type level transmitters, commercial evaluation personnel first need to confirm the characteristics of the measured medium. The DH709 series provides a variety of wetted material options, including 316L, titanium, and polytetrafluoroethylene, suitable for liquids with different chemical properties.

The process connection method is also an important consideration. The PT311L3 series supports multiple installation methods such as thread, flange, and clamp, with flange sizes available from DN25 to DN150, meeting the interface requirements of different tanks. In terms of output signals, the YKKT-1C series simultaneously provides multiple interfaces such as 4-20mA, 0-10V, and RS485, facilitating integration with various control systems.

4. Key points for installation and maintenance

When installing DB502 series rigid stem insertion type level transmitters, care should be taken to avoid the feed inlet and stirring areas to prevent measurement interference. When used in viscous media, it is recommended to choose the conical probe design of the PLUS series, which can effectively reduce material buildup.

In daily maintenance, the condition of sealing components should be checked regularly, especially when the OM133T series is used in corrosive environments. BOS-H208-K series products have a built-in self-diagnosis function, and the sensor status can be judged through the output signal, greatly reducing the risk of unexpected downtime.
