In flammable, explosive and high-risk industrial fields such as petrochemical and natural gas industries, safety, stability and precision of pressure measurement serve as core guarantees for smooth production line operation. The flameproof pressure transmitter is a high-precision industrial measuring and control equipment specially developed for explosive hazardous areas. Adopting mature sensing technology and rigorous flameproof structural design, it can accurately measure the pressure of liquid, gas and steam media, and stably convert physical pressure signals into standard 4-20mA current signals or RS485 digital signals for data collection and analysis by remote control systems. It is the top-choice core equipment for industrial automatic measurement and control in explosive environments.
This flameproof pressure transmitter is equipped with high-grade Ex db IIC T6 Gb flameproof construction, fully complying with safety standards for high-risk explosive locations. Its dedicated sealed flameproof housing effectively isolates internal electric arcs and high temperatures, eliminating ignition risks at the source. It can operate stably for a long time in hazardous atmospheres mixed with explosive gas, vapor and air without posing safety hazards, fully suitable for all Category II high-risk explosive work sites with superior compliance and safety performance.
In terms of performance configuration, the flameproof pressure transmitter features all-round robust protection. Built with an advanced digital temperature compensation system, it effectively offsets measurement errors under wide temperature ranges and greatly expands the applicable operating temperature spectrum, maintaining precise readings under both high and low temperature conditions. Equipped with an efficient lightning protection module, it offers strong resistance to radio frequency and electromagnetic interference, coping with complex electromagnetic environments on industrial sites and preventing signal drift and data distortion. The product also delivers excellent shock resistance, overload resistance, vibration resistance and corrosion resistance to adapt to harsh industrial conditions and avoid equipment wear and failures.
Body materials are selected precisely according to working conditions to balance durability and professionalism. For working ranges below 6 Bar, the flameproof pressure transmitter adopts 304 and 316 stainless steel, which resists corrosion and oxidation for measuring common corrosive media. For ranges ≥6 Bar, it is upgraded with a probe paired with a 304 stainless steel electronic housing, featuring high compression and impact resistance for severe high-pressure scenarios. The whole unit reaches IP65 protection class with outstanding dustproof and waterproof performance, suitable for complex installation environments including outdoor plants and factory areas.
The flameproof pressure transmitter boasts outstanding installation compatibility. It supports direct cable outlet via two types of flameproof back fittings: M20*1.5 and G1/2, enabling convenient wiring, superior tightness and efficient installation & commissioning. Powered by a high-precision sensing core, the device features fast frequency response and long-term stable measurement with accurate and rapid data transmission, greatly cutting subsequent operation and maintenance costs.
Widely applied in petrochemical, natural gas and flameproof hydraulic & pneumatic control systems, the flameproof pressure transmitter covers all measurement and automatic control scenarios in explosive industrial processes. With core strengths of high safety, stable performance and wide adaptability, it provides dual guarantees of safety and precision for intelligent, accurate measurement and control on high-risk explosive industrial production lines.
