Is the wiring diagram of the SMP131-TLD-L105GS-D1-F-53-4G15压力 transmitter troubling many operators? This article will break down the installation challenges of diffused silicon liquid and gas pressure sensors in 3 steps, helping you quickly master the wiring essentials and troubleshooting techniques for models such as KYB-800 and HTJ-HTJ110.

I. Core Principles and Definition of Pressure Transmitter Wiring Diagrams

Diffused silicon liquid and gas pressure transmitters (such as models SMP131-TLD-L105GS-D1-F-53-4G15 and KYB-800) convert pressure signals through the piezoresistive effect of silicon crystals. Their wiring diagrams are essentially electrical isolation designs for the sensor, power supply, and signal output in accordance with the IEC 61508 standard, ensuring stable transmission of 4-20mA or 0-10V standard signals. Taking HTJ-HTJ100 as an example, its working principle relies on a Wheatstone bridge structure, and wiring errors may result in accuracy loss (such as dropping from 0.5% to 1.5%) or directly damage sensitive components.

II. 3-Step Standardized Wiring Operation Guide

Step 1: Identify the Interface Type

Compare the interface differences between models such as PT124B-210-1MPa-G1/2 and DG1300-BZ-B-2-10-CJ-AE:

Step 2: Implement Anti-Interference Wiring

According to the requirements of the LD-108-3PBA793 manual, the following must be observed:

• The distance between signal lines and power lines must be ≥30cm
• RS485 communication requires twisted pair shielded cable (such as the standard SK-DBS316E1ERC2L-2m cable)
• Grounding resistance ＜4Ω (in compliance with the GB/T 15479-2015 standard)

III. Typical Fault Diagnosis and Accuracy Calibration

When HTJ-HTJ110 experiences zero drift, you may follow the NS-I pressure transmitter calibration procedure:

1. Disconnect the load and measure whether the power supply terminal voltage is within the 18-30VDC range
2. Apply 50% of full-scale pressure using a standard pressure source, and compare the difference between the displayed value and the standard instrument
3. Adjust the zero-point parameters through the HART protocol (applicable to intelligent models such as DG1300-BZ-B-2-0.8-CJ-AE)
