Analysis of the Relationship Between Measuring Range and Price of the HY301 Split-Type Submersible Level Transmitter
The measuring range of a split-type submersible level transmitter is one of the core factors affecting its price. Taking the HY301 series as an example, its measuring range usually covers from 0-5 meters to 0-100 meters. The larger the measuring range, the higher the requirements for sensor material strength, sealing performance, and signal processing capability, so the price shows a stepwise increase. For example, the price of a HY301 split-type submersible level transmitter with a 0-10 meter measuring range may be in the range of 2000-3000 yuan, while a model with a 0-50 meter measuring range may reach 5000-7000 yuan.
Technical evaluators should note that a larger measuring range is not always better. An excessively large range may lead to reduced accuracy, while a range that is too small cannot meet actual measurement requirements. It is recommended to select a model with a measuring range slightly greater than the maximum measured value based on the liquid level fluctuation range in the actual application scenario, so as to balance cost-effectiveness and measurement accuracy.
Price Comparison of HY301 Transmitters with Different Measuring Ranges
*Note: Actual prices may fluctuate depending on material (such as 316L stainless steel or titanium alloy), protection rating (IP68 or higher), and output signal type (4-20mA or RS485).
Price and Performance Comparison Between HY301 and Other Mainstream Models
In the field of split-type submersible level transmitters, in addition to HY301, models such as STK633, WIDEPLUS-LC, and PM510 have also attracted widespread attention. The following are the key comparison points:
- STK633 Series: The official website shows its price range as 2500-4000 yuan. Its feature is a modular design for easy maintenance, but the upper measuring range limit is relatively low (up to 50 meters)
- WIDEPLUS-LC: Priced at about 3000-5000 yuan, its advantage lies in operation over a wide temperature range (-40℃~125℃), making it suitable for extreme environments
- PM510: In the 4500-6500 yuan price range, it adopts ceramic capacitive sensing technology and offers strong corrosion resistance, making it especially suitable for the chemical industry
- BTL902: A high-end model priced between 10000-15000 yuan, featuring high accuracy of 0.1%FS and a dual-cavity lightning protection design
Five Major Technical Parameters Affecting Price
- Measurement Accuracy: The price difference between 0.5%FS and 0.25%FS models can reach 15-20%
- Media Compatibility: Measuring corrosive media requires a Hastelloy diaphragm, increasing cost by 30-50%
- Explosion-Proof Certification: The Ex d IIC T6 explosion-proof certified version is 25-40% more expensive than the standard version
- Communication Protocol: Models supporting HART or Modbus protocols carry a premium of 10-15%
- Long-Term Stability: High-stability versions with annual drift <0.1% are priced 20-30% higher
Purchasing Recommendations and Industry Application Cases
For different industry scenarios, we recommend differentiated configuration solutions:
Municipal Water Supply Systems
It is recommended to choose the HY301 0-20 meter measuring range basic version (about 3500 yuan), which can meet clean water measurement requirements when combined with an IP68 protection rating. A water plant in a provincial capital adopted this configuration and achieved 18% cost savings across 500 monitoring points.
Petroleum Storage and Transportation Sector
Explosion-proof PM510 or XT21R series models (priced at 6000-9000 yuan) should be selected, with intrinsic safety design certified by ATEX. An application case at a coastal refinery shows that this configuration had a failure rate of 0.2 times/year over a 5-year service cycle.
Food and Pharmaceutical Industry
The HT801 split-type submersible level transmitter (4000-5500 yuan), with its all-316L stainless steel material and hygienic connection method, has become the preferred choice for aseptic filling lines and complies with FDA certification requirements.
