Our explosion-proof pressure sensor adopts a high-performance pressure-sensitive chip, combined with advanced circuit processing and temperature compensation technology, to convert pressure changes into linear current or voltage signals. Our company offers two output signal options: analog and RS485, which can be connected to on-site PLCs, configuration software, HMI screens, or industrial controllers. Additionally, our networked data concentrators or monitoring hosts can be used to upload data to our free cloud platform, allowing users to view real-time data, historical records, and alarm logs via a computer or mobile app.
Additionally, the sanitary (flush diaphragm) pressure sensor is based on this pressure sensor but features a welded, sealed isolation diaphragm. This diaphragm sealing device comes in various structural designs, making it particularly suitable for high-temperature, high-viscosity, and crystallized media, as well as environments prone to clogging. It is also ideal for pressure measurement in sanitary and pharmaceutical applications.

Applications
This explosion-proof pressure sensor is compact and easy to install, with an optional LCD display. Its housing is made of stainless steel, providing waterproof and corrosion-resistant properties, making it suitable for measuring gases or liquids that do not corrode stainless steel. It can measure gauge pressure, negative pressure, and absolute pressure, making it an ideal choice for industrial process pressure measurement. It is widely used in water plants, refineries, wastewater treatment plants, construction materials, light industry, and the machinery sector for measuring the pressure of liquids, gases, and steam.
Explosion-Proof Pressure Sensor Installation
When you receive the explosion-proof pressure sensor provided by our company, please carefully read the manual and check the packaging list.
During installation, check whether the on-site interface matches the sensor’s connection type and thread specifications. When connecting, tighten slowly and avoid applying torque directly to the sensor housing—apply torque only to the hexagonal section of the pressure interface. Ensure that the explosion-proof pressure sensor is installed vertically to the ground. Use a wrench to tighten it from the hexagonal nut at the base of the sensor, avoiding direct rotation of the upper part of the sensor. Choose an installation location that allows for easy operation and maintenance, and keep it as far away as possible from sources of vibration or heat.
When connecting the power supply, strictly follow the wiring instructions provided by our company.
Renke explosion-proof pressure sensor is a precision instrument. Do not disassemble it arbitrarily during transportation or installation. Additionally, avoid collisions, drops, or contact with sharp objects on the sensor diaphragm to prevent damage to the core component.
Ensure proper sealing of the external thread on the pressure sensor; otherwise, inaccurate or unstable pressure readings may occur.
