In the field of industrial automation, the 40-1005 pressure transmitter, with its excellent diffused silicon HSMAN sensor technology, has become a cost-effective choice. As a professional high-tech enterprise, Xi'an Shenghongchuang Instrumentation Co., Ltd. reveals its price advantages and performance features for you, helping you easily select suitable flow control equipment.

Analysis of Diffused Silicon HSMAN Sensor Technology

The diffused silicon HSMAN pressure sensor adopts advanced MEMS technology and achieves high-precision pressure measurement through the piezoresistive effect of silicon wafers. Its core advantage lies in long-term stability superior to traditional strain gauge technology, with temperature drift controlled within ±0.05%FS/℃. Taking model 40-1005 as an example, its measuring range covers 0～250MPa, with an accuracy of 0.25 grade, making it especially suitable for industrial scenarios requiring long-term stable operation, such as hydraulic systems and constant-pressure water supply.

Key Indicators for Procurement Decision-Making

Technical evaluators should focus on three core indicators: first is the long-term stability parameter, with the annual drift of model 40-1005 being only ±0.1%FS; second is media compatibility, as its 316 stainless steel diaphragm can withstand the vast majority of corrosive media; finally, installation adaptability should be considered, with multiple interface specifications provided such as M20×1.5 and G1/4. For occasions with high anti-clogging requirements, domestic flush diaphragm pressure transmitter HJ351 anti-clogging 2088 pressure sensor is recommended, and its flush diaphragm structure can effectively avoid particle accumulation.

FAQ on Common Selection Misunderstandings

• Q：Does price determine performance?
  A：Not absolutely, the 40-1005 uses an HSMAN sensor chip, and although it is moderately priced, its performance benchmarks against imported brands
• Q：How to verify the authenticity of the calibration certificate?
  A：Require the supplier to provide a calibration report issued by a CNAS-accredited laboratory, such as the ex-factory inspections of Xi'an Shenghongchuang, all of which include traceable serial numbers
• Q：How to choose between three-wire and two-wire systems?
  A：For long-distance transmission, the two-wire 4-20mA is preferred, while for fast response, a three-wire 0-10V output is recommended

Industry Application Solutions

In the monitoring system of a thermal power generating unit, we configured a 40-1005 pressure transmitter array for a customer, together with model HJ351 for steam pipeline monitoring. After implementation of the solution, the system measurement error was reduced from the original 1.2% to 0.3%, and no recalibration was required within three years. This combination can not only meet high-pressure operating condition requirements (the 40-1005 range reaches 250MPa), but also solve coal ash blockage problems through the domestic flush diaphragm pressure transmitter HJ351 anti-clogging 2088 pressure sensor.
