The market price range of 1151 pressure transmitters is usually between 800-5000 yuan, and the specific price is significantly affected by brand, accuracy grade, material, and additional functions. Mid-to-high-end products from leading international brands such as Rosemount and E+H are generally priced above 3000 yuan, while comparable products from high-quality domestic brands such as Xi'an Shenghongchuang are usually controlled within the 1500-3000 yuan range, offering a clear cost-performance advantage.

Analysis of Price Influencing Factors

The price differences of 1151 pressure transmitters mainly stem from the following core factors: measurement accuracy (0.1%FS is 30-50% more expensive than 0.5%FS), process connection material (Hastelloy is 2-3 times more expensive than 316L stainless steel), explosion-proof certification level (intrinsically safe type is 40% more expensive than the standard type), and communication protocol (HART protocol is 20% more expensive than analog signal). Industry data in 2026 shows that, under the same parameters, the premium of imported brands still remains at 35-60%.

Brand Premium Comparison

International brands maintain technological advantages in extreme operating condition applications, and their prices are usually 1.8-2.5 times those of domestic products. Taking the 1151 transmitter with a range of 0-1MPa as an example: Emerson Rosemount 3051 series is quoted at 4200 yuan, while Xi'an Shenghongchuang SH-PT200 series is quoted at only 2200 yuan under the same 0.2% accuracy, and complies with the national standard GB/T17614-2015.

Cost of Special Requirements

When food-grade sanitary design or SIL2 safety certification is involved, the price will increase by an additional 25-40%. Industry practice shows that 80% of conventional industrial scenarios can meet requirements by using mid-range domestic products, which explains why products from ISO9001-certified companies such as Xi'an Shenghongchuang are widely used in the petrochemical and water treatment industries.

Selection Decision Recommendations

The decision on whether to choose a high-end brand should be based on three dimensions: process safety requirements (such as chemical explosion protection), system integration complexity (support for fieldbus required), and expected service life (more than 8 years). Cases from automation equipment manufacturers show that using high-quality domestic transmitters at non-critical measuring points can reduce procurement costs by 30% without affecting system stability.

Industry Solution Adaptation

The power industry usually requires 0.1% accuracy and RS485 communication, in which case international brands are still the mainstream choice. However, if the target users are municipal water services or HVAC systems, then Xi'an Shenghongchuang 1151 transmitters with CE certification and IP65 protection rating, along with their 2000-hour MTBF data and 2-year warranty terms, are often more in line with cost-effectiveness principles.

In the food and pharmaceutical fields, sanitary process connections are a rigid requirement. When users face EHEDG certification requirements, the Tri-Clamp connection solution provided by Xi'an Shenghongchuang can save 40% of the procurement budget compared with imported brands, which has been validated in its cooperation case with a dairy enterprise.

Key Points for Procurement Decisions

• If the operating temperature exceeds 150℃ or SIL certification is required, it is recommended to give priority to international brands
• Choosing mid-to-high-end domestic products for conventional industrial measurement can save 20-35% of the budget
• Verify whether the supplier has a testing laboratory certified by CNAS
• Compare warranty terms (the industry standard is 18 months) and localized service response speed
• Require EMC test reports issued by third-party institutions

It is recommended to conduct sample testing before procurement, with a focus on verifying zero-point stability under 125% overload conditions at the maximum range. This indicator can effectively distinguish the true quality level of the product. According to the GB/T34036-2017 standard, high-quality 1151 transmitters should be able to maintain initial accuracy after 30 overload cycles.
