Introduction

When purchasing a UMD-98 split-type submersible level transmitter, are you troubled by the many model parameters? This article analyzes key indicators such as the working principle of BXY620C3 and comparisons of DS2620 manufacturers, helping you avoid misunderstandings when selecting HDP601S and understand the true quality of EB2088T. As a professional manufacturer of flow control equipment, we have specially compiled 5 core parameters to help you easily find suitable products such as WIDEPLUS-LR or HM21R.

1. Measuring range and accuracy: the primary considerations for selection

The measuring range of a split-type submersible level transmitter directly determines its applicable scenarios. Taking UMD-98 as an example, its typical measuring range covers 0-1m to 0-100m, while BXY620C3 is specifically designed for high-temperature and high-pressure environments, with a maximum pressure resistance of 10MPa. Please note:

• Matching actual requirements: Chemical storage tanks usually require a 0-20m range, while water conservancy monitoring may require 0-50m
• Accuracy class: The DS2620 series reaches 0.1%FS, while HM21R is 0.25%FS. For scenarios such as wastewater treatment, it is recommended to select within 0.2%
• Overload protection: WIDEPLUS-LR has 150% overrange protection capability

According to the GB/T 17614-2018 standard, industrial-grade transmitters should at least meet 0.5 accuracy class, which is also the basic configuration of mainstream models such as EA118.

2. Media compatibility and material selection

Different models vary significantly in their adaptability to media:

Special reminder: Although the ceramic sensor of MK-136 is wear-resistant, it is not suitable for special media such as hydrofluoric acid. Please refer to the HG/T 20507 industry specification when purchasing.

3. Electrical characteristics and output signals

The signal output of modern transmitters has developed from the traditional 4-20mA to multi-protocol compatibility:

1. Basic models: EA118 and similar models provide standard two-wire 4-20mA output
2. Smart versions: DS2620 supports the HART7.0 protocol and can superimpose digital signals
3. Bus-type: WIDEPLUS-LR is equipped with a PROFIBUS-DP interface

According to on-site wiring conditions, the 24VDC-powered UMD-98 is more suitable for explosion-proof areas than the 220VAC-powered BXY620C3, and its intrinsic safety parameters must comply with the GB3836.1-2010 standard.

4. Environmental adaptability and protection rating

Different installation environments have strict requirements for equipment:

• IP protection: HM21R reaches IP68 and can be used for long-term immersion
• Temperature range: The -40~125℃ range of EB2088T is suitable for severely cold regions in northern areas
• Explosion-proof certificationATEX/IECExHDP601S3 years48-hour responseISO 9001

  It is recommended to give priority to brands such as DS2620 that provide on-site calibration services. Their equipped NIST-traceable calibration equipment can ensure measurement traceability.
