Shanghai Zhaohui expands pressure sensing lineup for industrial automation

Shanghai Zhaohui Pressure Apparatus Co., Ltd. is highlighting its pressure sensor cores, melt pressure transmitters, and mercury-free gauges as industrial manufacturers look for more precise process monitoring. The company says its portfolio supports plastics, rubber, chemical, energy, automation, and other sectors, with products exported to more than 50 countries and regions.

Why it matters: - Pressure sensing is a core input for industrial automation, process control, and equipment monitoring. - Shanghai Zhaohui Pressure Apparatus Co., Ltd. is positioning its sensor cores, transmitters, and gauges for manufacturers that need stable measurement in demanding environments. - Mercury-free melt pressure products may appeal to buyers looking for alternatives to traditional mercury-containing instrumentation.

What happened: - Shanghai Zhaohui Pressure Apparatus Co., Ltd., founded in 1999 and headquartered in Shanghai, is promoting its pressure measurement portfolio for industrial customers. - The company’s product range includes pressure sensors, pressure transmitters, melt pressure transmitters, melt pressure gauges, differential pressure products, OEM pressure sensors, vacuum pressure transmitters, pressure indicators, controllers, and related instrumentation. - The company says its products are used in plastics and rubber processing, energy, automation, chemical production, process control, and other industrial fields. - More information about the company and its product lines is available at the company’s website.

The details: - Pressure sensor cores convert physical pressure changes into measurable signals that can be processed by transmitters, gauges, controllers, or monitoring systems. - The company’s melt pressure lineup includes standard, capillary, intelligent LCD display, high-accuracy, sanitary, intrinsically safe explosion-proof, flange-type, and other configurations. - Shanghai Zhaohui also offers the Mercury Free Melt Pressure Gauge, including capillary versions with signal output. - The company lists output options such as 0–5 V, 0–10 V, and 4–20 mA, along with different electrical and process connections and temperature measurement configurations. - The product range includes pressure-and-temperature combinations, including melt pressure transmitters with optional thermocouple configurations. - Shanghai Zhaohui says its portfolio includes diffused silicon and monocrystalline silicon pressure sensing technologies, plus standard diffused silicon, high-stability monocrystalline silicon, differential pressure sensor, and micro-melted pressure sensor products. - The company also offers industrial pressure products including flameproof pressure transmitters, vacuum pressure transmitters, pressure sensors for spraying equipment, and other specialized instruments. - Its broader measurement lineup also covers temperature, flow, liquid-level, oil-quality transmission, torque sensing, and safety protection. - Company information says the Shanghai headquarters includes a dedicated R&D center, while the Hunan production base supports annual output of millions of sensors and related products. - The company reports ISO 9001 quality management certification and approvals or certifications including CMC, Ex, MA, CE, RoHS, ATEX, IECEx, and UKCA on selected products. - The company says its products are distributed in China and exported to more than 50 countries and regions.

Between the lines: - The push into mercury-free melt pressure products reflects a broader shift toward cleaner material choices and more application-specific industrial instrumentation. - Offering both transmitters and gauges gives equipment designers flexibility, since transmitters support remote monitoring and automation while gauges provide local reading. - Multiple signal outputs and sensor structures suggest the company is targeting OEM customers that need instrumentation matched to different machine architectures. - The range of certifications points to a strategy aimed at regulated industrial environments where compliance can influence purchasing decisions.

What's next: - Shanghai Zhaohui is likely to keep leaning on its pressure, temperature, and multi-parameter sensing portfolio as industrial customers seek integrated measurement systems. - The company’s OEM sensor-core business may remain a key path for custom equipment builds and specialized process applications. - Demand for high-temperature, hazardous-area, and process-specific pressure products should continue to shape product development in melt processing and related sectors.

The bottom line: - Shanghai Zhaohui is using its long-running pressure measurement business to serve industrial buyers that need specialized, configurable sensing products rather than one-size-fits-all instrumentation.
