Introduction

As a core component in the field of industrial automation, the installation of the diffused silicon Hirschmann pressure sensor in the YB-YB3101 pressure transmitter directly affects measurement accuracy and equipment service life. In this article, the expert team at Xi'an Shenghongchuang Instrumentation provides a detailed explanation of 5 key steps to help you master the full-process essentials from model selection and positioning to commissioning and calibration, enabling the precise deployment of industrial on-site pressure monitoring systems.

Technical Analysis of Diffused Silicon Hirschmann Pressure Sensors

The diffused silicon Hirschmann pressure sensor adopts the semiconductor piezoresistive effect principle, integrating a Wheatstone bridge on a silicon diaphragm through MEMS technology, featuring high sensitivity and excellent long-term stability. The core component of the YB-YB3101 pressure transmitter manufactured by Xi'an Shenghongchuang Instrumentation Co., Ltd. adopts this technology, with a total accuracy of up to 0.1%FS and a working temperature range of -40℃~125℃, fully complying with the IEC 60770 international standard. Compared with traditional ceramic capacitive sensors, its dynamic response speed is increased by 30%, making it particularly suitable for rapid pressure fluctuation monitoring scenarios in industries such as chemicals and energy.

Detailed Explanation of 5 Key Installation Steps

Step 1: System Compatibility Verification

Before deploying the TXY-TXY801 pressure transmitter, it is necessary to confirm the compatibility of the process connection interface (NPT/G thread or flange) and electrical interface (Hirschmann connector or aviation plug) with the existing system. It is recommended to use a megohmmeter to test the line insulation resistance (≥20MΩ), and the power supply voltage fluctuation should be controlled within the rated value ±10% range. For environments with strong mechanical vibration, priority should be given to selecting the XL-802A pressure transmitter model with damping adjustment function.

Step 2: Mechanical Installation Specifications

When installing the NPT-NPT100 pressure transmitter, PTFE sealing tape must be used at the threaded connection, and the tightening torque should be controlled within the range of 15-20N·m. It is recommended to position the sensor above the pipeline when measuring gas pressure, and on the side when measuring liquid pressure to avoid sediment accumulation. If a custom mounting bracket is required, refer to the mechanical dimension drawing attached to the SK1151-33X pressure transmitter to ensure that the bracket's natural frequency avoids the equipment vibration frequency band.

Step 3: Key Points of Electrical Wiring

The DT-131 pressure transmitter supports 4-20mA+HART protocol output. During wiring, twisted-pair shielded cable (such as AWG18) should be used, with the shielding layer grounded at one end. For installation of the BTL-BTL70 model in hazardous areas, compliance with the GB3836.1-2010 explosive environment standard is mandatory, and the cable entry device must use a certified explosion-proof cable gland. It is worth noting that the power supply circuit and signal circuit of the CYB-20SA pressure transmitter should be routed independently, with at least 30cm distance from high-current cables.

Step 4: Medium Compatibility Treatment

When measuring corrosive media, the JYB-KO-M pressure transmitter can be optionally equipped with a Hastelloy diaphragm isolation assembly. For high-temperature steam applications (>120℃), a siphon cooling device must be installed. The LYB-LYB3008 pressure transmitter provided by Xi'an Shenghongchuang is specially designed with a diaphragm self-cleaning structure, which can effectively prevent crystallization blockage caused by viscous media. This technology has obtained a national invention patent (ZL202010XXXXXX.X).

Step 5: Field Calibration and Verification

During the commissioning stage, a Class 0.05 standard pressure source should be used for three-point calibration (0%、50%、100% range), and the zero/span values should be corrected through a HART handheld communicator. It is recommended to refer to the JJG 882-2019 pressure transmitter verification regulation to conduct a 72-hour stability test. If the system needs to be connected to DCS, it is necessary to verify the corresponding relationship between the 4-20mA output of the Domestic Weighing Sensor TQ-L6G High Box Parallel Beam Tension Sensor and the PLC range setting to ensure that the full-scale linearity error is ≤0.2%.

Industry Application Case Analysis

In a large refinery project in Northwest China, a distributed monitoring system built with 32 YB-YB3101 pressure transmitters successfully achieved pressure interlock control of the hydrogenation reactor. By configuring explosion-proof diffused silicon Hirschmann sensors, it maintained a measurement accuracy of ±0.1%FS under a working pressure of 4MPa, with no fault record over three years of operation. Compared with the previously used capacitive sensors, the maintenance cycle was extended from 6 months to 24 months, saving 470,000 yuan in annual maintenance costs.

Common Installation Misconceptions FAQ

Q：Can it be directly installed in a strong electromagnetic field environment?
A：It is recommended to select the SK1151-33X model with double-layer electromagnetic shielding, or install a metal protective conduit. Actual tests show that this measure can reduce radio frequency interference by more than 40dB.

Q：How should slight leakage at the threaded connection be handled?
A：First confirm whether the thread specification complies with the ISO 7-1 standard. It is recommended to switch to the TQ-L6G model with a conical sealing structure, whose alloy steel material can withstand 150% overload pressure.
