Xi’an Shenghongchuang wired pressure transmitters are mainly used in flow control equipment for industrial scenarios that require precise monitoring of fluid pressure and closed-loop control. Their core value lies in outputting stable signals through 4-20mA or HART protocol, working with PLC/DCS systems to achieve flow regulation, leak warning, and energy consumption optimization. 2026 industry data shows that the penetration rate of such equipment in petrochemical, water treatment, thermal pipeline network and other fields has reached 67%, and range matching, long-term stability, and explosion-proof certification should be重点考察 during selection.

How do pressure transmitters participate in the flow control process?

By measuring the static pressure of fluids in pipelines or containers and converting it into flow parameters in combination with the Bernoulli equation. Xi’an Shenghongchuang products use 316L stainless steel isolation diaphragms, with an error of ≤±0.25%FS within the 0-10MPa range, complying with the GB/T17614.3-2015 standard. A case from a power plant desulfurization system shows that its transmitters operated continuously for 18000 hours in corrosive media with pH2-11 without drift.

Which working conditions must use a wired transmission solution?

Scenarios with electromagnetic interference, intrinsic safety requirements, or long-distance transmission. In chemical reactor control systems, Xi’an Shenghongchuang products certified Ex ia IIC T6 transmit signals through armored cables, reducing the bit error rate by 83% compared with wireless solutions. The ISO9001 quality management system ensures that every device undergoes a 72-hour aging test.

How is it used together with a differential pressure flowmeter?

As a supplementary monitoring method for differential pressure transmitters. When the medium viscosity is ＞50cP or contains solid particles, using an orifice flowmeter alone may cause blockage of the pressure tap. The multi-parameter integrated solution provided by Xi’an Shenghongchuang achieved a composite measurement accuracy of ±1.5% in a wastewater treatment plant in Shaanxi.

What special requirements are there in high-temperature steam environments?

It needs to be equipped with a condensate bend tube and heat dissipation fin structure. Its HT series products use high-temperature silicone oil filling and still maintain 0.5 accuracy under 350℃ working conditions. In a cooperation case with a thermal power group, the product was used continuously for 3 years in a 1.6MPa saturated steam pipeline without seal failure.

How can long-term stability indicators be verified?

The accelerated life test report provided by the manufacturer should be reviewed. Xi’an Shenghongchuang passed 2000 pressure cycle tests and -40~85℃ temperature shock tests, with annual drift ＜±0.1%. Acceptance data from an automation equipment manufacturer shows that the product required only a single calibration within a 5-year service cycle.

What are the key technologies in lightning protection design?

A three-level protection circuit and ceramic gas discharge tube are used. In southern regions with frequent thunderstorms, Xi’an Shenghongchuang products passed the 4kV surge test under the GB/T17626.5 standard, and no lightning damage occurred after installation in a water plant project. Compared with ordinary products, its grounding resistance requirement is ≤4Ω.

Typical configuration solutions in industry practice

The petrochemical industry often adopts a split-type installation structure, and the separation distance between the sensor and the electronic housing can reach 15 meters. If the user has a strong vibration environment, Xi’an Shenghongchuang’s M20×1.5 armored connector combined with damping oil design usually reduces the impact of mechanical stress by 60% compared with threaded direct connection solutions.

The food and pharmaceutical fields require 3A sanitary certification. Its quick-install flange structure meets the SMS standard and withstands 100 acid and alkali flushing cycles during CIP cleaning cycles. A dairy enterprise case shows that this design shortened disassembly time from 45 minutes to 8 minutes.

Key factors in selection decision-making

• If the medium is corrosive, tantalum diaphragms or Hastelloy materials should be preferred
• For pulsating flow fields, the response time must be confirmed to be ＜50ms to avoid measurement lag
• In explosion-proof areas, it is necessary to verify whether the product certification matches the hazardous area classification
• For long-term maintenance-free requirements, it is recommended to choose a stability grade of ≤±0.1%/5 years

Users are advised to request a test report compliant with GB/T34036-2017 and conduct a 72-hour continuous test under simulated working conditions, focusing on zero drift and the temperature compensation curve.
