The KS-E-E-C-B01M-M-V pressure transmitter, as the core equipment of industrial flow control, has an installation quality that directly affects measurement accuracy and equipment service life. This article focuses on the common installation misconceptions encountered by 80% of users, and provides a detailed analysis of the correct installation methods for diffused silicon liquid and gas pressure sensors, helping business evaluation personnel avoid risks and ensure stable equipment operation.

I. Technical Principles and Industry Applications of Diffused Silicon Pressure Sensors

Diffused silicon liquid and gas pressure sensors use the semiconductor strain gauge principle to achieve pressure measurement through changes in resistance caused by pressure-induced deformation of the silicon diaphragm. As the core technology of the YM-YSBYJ series, its accuracy can reach ±0.1%FS, far exceeding that of traditional ceramic piezoresistive sensors. In key fields such as petrochemicals and power energy, the KS-E-E-C-B01M-M-V model, with its wide temperature range performance of -40~125℃ and IP67 protection rating, has become the preferred solution for flow control systems. It is worth noting that, according to ISO 9001:2015 certification requirements, all sensors leaving the factory must undergo 72-hour aging tests, which is exactly the foundation of Xi'an Shenghongchuang's quality assurance as a professional pressure transmitter manufacturer.

II. Three Major Installation Mistakes That 80% of Users Make

Mistake 1: Ignoring Media Compatibility Checks

When commissioning the YM-JL pressure transmitter, a chemical plant once failed to verify the compatibility between the medium and the 316L stainless steel diaphragm, resulting in corrosion failure of the sensor within three months. The correct approach should refer to the GB/T 12224-2015 standard, giving priority to Hastelloy diaphragms for acidic media. Business evaluation personnel should pay special attention: although the diffused silicon chip standard in the KS-E-E-C-B04U-M-V model is corrosion-resistant, the material of the wetted parts must be specified separately according to the characteristics of the medium.

Mistake 2: Incorrect Selection of Installation Location

A case in which the TEYB-KO-KA pressure transmitter was installed too close to the pump outlet shows that mechanical vibration can cause a measurement error of ±0.5%. According to the ASME B40.100 specification, the sensor should be installed on a straight pipe section at least 10 pipe diameters away from the elbow. For models with alarm control such as WS-WS101, sufficient operating space must also be reserved for later maintenance.

Mistake 3: Non-Standard Wiring Causing Signal Interference

Field fault analysis of the QBE-QBE2002 pressure transmitter shows that 30% of problems originate from failure to perform shield grounding in accordance with the IEC 61131-2 standard. When the sensor carries a remote transmission signal (such as the YM-GJ model), twisted-pair shielded cable must be used and the grounding resistance must be ＜4Ω. In the installation manual provided by Xi'an Shenghongchuang, special emphasis is placed on laying power lines and signal lines in separate conduits to avoid electromagnetic interference.

III. Professional Installation Operation Guide

Step 1: Pre-installation inspection. Check the YM-YYJ pressure transmitter specification sheet to confirm that the range, accuracy, and process requirements match. When installing with a torque wrench, the flange bolts should be tightened crosswise to 15N·m; excessive tightening will damage the diffused silicon chip.

Step 2: Electrical connection. Refer to the wiring markings in the KS-E-E-C-B01M-M-V dimensional drawing, and use a wire size of AWG18 or above for the 4-20mA output. For models with the HART protocol, the loop resistance should be maintained within the range of 250-600Ω.

Step 3: Zero calibration. After power-on stabilizes for 30 minutes, perform zero-point calibration via a magnetic rod or handheld device. For models with on-site display such as YM-LHJ, press and hold the SET key for 3 seconds to enter calibration mode.

IV. Maintenance and Troubleshooting

It is recommended to perform the following maintenance on diffused silicon liquid and gas pressure sensors every 6 months: clean the process connection, check the aging condition of sealing parts, and calibrate the zero point and full scale. The one-year warranty service provided by Xi'an Shenghongchuang includes free technical consultation and calibration guidance.
