This article provides an in-depth analysis of the working principle of the YWKKT-1B split-type submersible level transmitter, with a full-process illustrated explanation from structural composition to signal output. As a professional manufacturer in the field of flow control equipment, Xi'an Shenghongchuang Instrumentation will guide you through the core technologies and key application points of this transmitter, helping distributors and end users understand the equipment operating mechanism and solve common issues such as XY530BA display and XEW502 model selection.

I. Definition and Core Structure Analysis

The YWKKT-1B split-type submersible level transmitter is a precision instrument that measures liquid depth through the pressure sensing principle. Its core consists of a stainless steel isolation diaphragm, a diffused silicon sensor, and a signal processing circuit. Unlike the KZY-KO-LAG split-type submersible level transmitter, the YWKKT-1B adopts a split-type design, allowing the probe and transmitter module to be installed separately, making it suitable for complex working conditions such as high temperature and corrosive media. Based on 20 years of sensor R&D experience, Xi'an Shenghongchuang Instrumentation has optimized and upgraded the key parameters in the XEW503 split-type submersible level transmitter manual, enabling the YWKKT-1B to maintain stable output even at the 0.5%FS accuracy class.

II. Technical Performance and Signal Output Process

When the hydrostatic pressure of the liquid acts on the probe diaphragm, the pressure is transmitted to the sensor through sealing oil and converted into a millivolt-level electrical signal by the Wheatstone bridge. After amplification and temperature compensation, the signal finally outputs a standard 4-20mA signal (as indicated by the accuracy class of the PTJ301S-01 split-type submersible level transmitter). Compared with the calibration process of the JSCW-50 split-type submersible level transmitter, the YWKKT-1B has a built-in automatic calibration algorithm, and users can remotely adjust the range through the HART protocol. Its technical parameters are as follows:

III. Typical Application Scenarios and Selection Guide

For the XEW502 split-type submersible level transmitter specification and model selection issues frequently encountered by distributors, we recommend selecting 316L or Hastelloy probe materials according to the medium characteristics (such as corrosiveness and viscosity). In a wastewater treatment plant case, the YWKKT-1B, together with the RS485 bus solution in the YH800 split-type submersible level transmitter wiring diagram, successfully achieved networking of 30 monitoring points. Compared with the display solution of the XY530BA split-type submersible level transmitter, this product supports LED/LCD dual-mode display and can perform fast on-site diagnostics using the verification tools for the KZY-KO-LAGE split-type submersible level transmitter.

IV. Common Problems and Professional Solutions

• Signal drift issue: Referring to the accuracy class requirements of the PTJ301S-01 split-type submersible level transmitter, it is recommended to perform calibration with a standard pressure source once a year
• Display abnormality handling: Check whether the power supply of the XY530BA display module is stable, and refer to Chapter 5 of the XEW503 manual for signal loop testing
• Installation precautions: Avoid contact between the probe and the tank wall. For the specific distance, refer to the anti-interference design specifications in the YH800 wiring diagram
