As a professional supplier in the field of flow control equipment, Xi'an Shenghongchuang Instrument Co., Ltd. provides you with a detailed explanation of the installation key points for the diffused silicon sensor of the LRDG-LRDG pressure transmitter. Focusing on the core needs of business evaluators, this article highlights 3 quick installation tips for diffused silicon liquid and gas pressure sensors, covering the technical performance and installation specifications of product series such as YM-bestace661 and CPT-CPT1, helping you improve equipment deployment efficiency.

Technical Principles and Industry Applications of Diffused Silicon Pressure Sensors

Diffused silicon sensors use the semiconductor piezoresistive effect principle, forming a Wheatstone bridge on the silicon chip surface through MEMS technology. When medium pressure acts on the sensitive element, resistance changes generate a millivolt-level signal, which is converted into a standard industrial signal output through the amplification circuit. In scenarios such as petrochemicals and power energy, the CPT-CPT1 pressure transmitter, with its high accuracy of 0.1%FS and IP67 protection rating, can stably measure liquid/gas pressure in the range of -0.1~60MPa. It is worth noting that, compared with traditional strain gauge sensors, diffused silicon technology has significant advantages such as small temperature drift (±0.02%FS/℃) and good long-term stability (±0.1%FS/year).

Detailed Explanation of 3 Core Installation Tips

Tip 1: Standardized Configuration of Process Connections

When installing the LRDG-LRDG pressure transmitter, flange or threaded connection methods must be selected in strict accordance with the GB/T 1226-2017 standard. For YM-bestace662 series products, it is recommended to use G1/2" male thread with PTFE sealing gasket, with torque controlled within the range of 35±5N·m. If measuring corrosive media, the CY-4000 pressure transmitter made of 316L stainless steel should be selected, and its flange sealing surface must be mirror-finished to Ra≤3.2μm according to the HG/T 20592 standard. Special reminder: the installation position should avoid turbulent flow areas such as pipeline elbows and valves, and the straight pipe section length must ensure 10D upstream and 5D downstream (D is the pipeline diameter).

Tip 2: Anti-Interference Solution for Electrical Wiring

In the two-wire 4-20mA output loop of the BBP-1 pressure transmitter, it is recommended to use shielded twisted pair cable with a cross-sectional area of ≥1.5mm². According to the IEC 61158-2 standard, the signal line should maintain a distance of more than 30cm from the power cable, and if necessary, it can be laid through a metal conduit. For PS-201 models with alarm control, the relay output terminal must be equipped with an RC snubber circuit (typical value: 100Ω+0.1μF), which can effectively suppress contact sparks. Actual test data show that this solution can reduce measurement errors caused by electromagnetic interference to below ±0.05%FS.

Tip 3: Environmental Adaptability Optimization Measures

When installing the C-C23 pressure transmitter under vibration conditions, it is recommended to add an anti-vibration bracket (natural frequency ≥25Hz) and use a flexible pressure guide tube connection. When the ambient temperature exceeds the -20~80℃ operating range, the LD-LD183 sensor must be equipped with heat dissipation fins or an insulation box. For high-humidity environments such as offshore platforms, the transmitter junction box should be filled with Dow Corning DC4 silicone grease to ensure the protection rating reaches the IP68 standard. Through the above measures, the equipment MTBF (mean time between failures) can be extended to more than 100,000 hours.

Technical Parameter Comparison and Selection Guide

In the field of displacement measurement, Domestic displacement sensor GHSD750 differential pull-rod linear displacement sensor spring-return inductive sensor uses the inductive principle to achieve ±5V analog output. Its micron-level detection accuracy and -20~120℃ operating temperature range make it especially suitable for industrial scenarios requiring high-precision displacement detection. When used together with pressure transmitters, this product can build a complete monitoring network for fluid control systems.

Common Installation Misunderstandings FAQ

Q: Can a pressure transmitter be installed directly at the pump outlet?
A: It is not recommended. Pump vibration and pressure pulsation will cause the measured value fluctuation of the LRDG-LRDG sensor to exceed ±2%, and it should be installed after isolation through a pulsation damper.

Q: Do diffused silicon sensors require regular calibration?
A: According to the JJG 882-2019 regulation, it is recommended to perform zero/full-scale calibration on key-point transmitters such as C-C23 every 12 months, and daily online diagnostics can be carried out through a HART communicator.
