Industrial Pressure Sensor ,High-Precision Industrial Pressure Transmitter with Customizable Variants
The Veswe pressure transmitter series is engineered for versatility, offering four distinct configurations to meet diverse industrial needs: the Standard Type with threaded connections, the Hygienic Type featuring tri-clamp sanitary fittings, the High-Temperature Type with extended heat dissipation fins, and a combined Hygienic + High-Temp model. Each unit serves as a robust industrial pressure transmitter, housed in a durable 2088-style enclosure with a white casing and blue protective cap. Whether deployed as a steam pressure sensor in boiling environments, a sanitary pressure sensor for food processing, or a chemical pressure sensor in corrosive settings, this device ensures reliable performance. The specialized designs allow it to function effectively as a flush diaphragm pressure sensor for viscous media or a high temperature pressure transmitter for extreme thermal applications, making it a comprehensive process pressure transmitter solution.

Flexible Data Transmission and Real-Time Monitoring Solutions
Maximize operational visibility with three flexible data access methods integrated into this electronic pressure transmitter. First, users can opt for an onboard digital display module, transforming the unit into a local digital pressure transmitter with real-time LED readouts and control buttons. Second, the device supports connection to external smart single-loop controllers for centralized panel monitoring. Third, for advanced remote management, the pressure transducer can output analog signals (acting as a 4 20ma pressure transducer or analog pressure sensor) or digital signals via RS485 (functioning as an RS485 pressure sensor). This connectivity enables integration with cloud platforms for real-time data viewing, over-limit alarms, and historical analysis on PCs or mobile devices. Such flexibility makes it ideal as a tank pressure sensor, boiler pressure sensor, or HVAC pressure transducer, ensuring seamless data flow into modern SCADA and IoT systems.

Premium Structure and Exquisite Craftsmanship for Safety
Designed solely for safety and stability, this stainless steel pressure transmitter features a fully isolated internal structure that protects sensitive electronics from dust, fog, and high-humidity environments. The manufacturing process emphasizes exquisite craftsmanship, beginning with rigorous component screening to ensure only top-tier materials are used. Every unit undergoes an 8-point precision calibration using GE’s fully automatic systems, guaranteeing accuracy across the full scale. This attention to detail ensures that whether used as a hydraulic pressure transducer, pump pressure sensor, or gas pressure sensor, the device maintains superior quality. The robust build also supports its role as a pressure level transmitter or differential pressure transducer in critical infrastructure, where reliability is paramount.

Advanced Protection Technologies and Traceability
To ensure long-term durability, each pressure probe is injected with a silicone gel layer that seals out air and moisture, preventing internal corrosion and extending service life. The device complies with international EMI protection standards, featuring reverse polarity protection and safeguards against transient overcurrent and overvoltage, making it suitable for electrically noisy environments where an intrinsically safe pressure transmitter or explosion proof pressure sensor might be considered. Furthermore, the unit employs laser-trimmed resistance technology for automatic temperature compensation and drift correction, ensuring stable readings despite ambient fluctuations. A unique laser-marked ID number on every water pressure sensor or refrigerant pressure sensor enables full lifecycle traceability, supporting efficient digital asset management and maintenance tracking.

Exquisite Workmanship and Core Engineering Features
The reliability of this piezoresistive pressure sensor is built on four key engineering pillars. The standard threaded probe allows for quick installation, while the integrated circuit system processes resistance changes with temperature compensation to output stable DC signals. Dual sealing protection with custom O-ring gaskets effectively blocks moisture ingress, enhancing the durability of this strain gauge pressure transducer. For sanitary applications, the hygienic flat diaphragm design offers an enlarged contact surface, strong overload capacity, and excellent corrosion resistance. These features make the device adaptable as a gauge pressure sensor, absolute pressure sensor, or submersible pressure sensor equivalent, capable of handling aggressive fluids and varying process conditions with ease.


Global Applicability and Diverse Industrial Deployment
With a subtle world map motif underscoring its global readiness, the Veswe pressure transmitter is designed for deployment in varied environmental conditions worldwide. Its robust construction and precise measurement capabilities make it an essential component for reservoir level monitoring, wastewater level sensor applications, and groundwater level sensor networks when configured as a pressure level transmitter. From acting as a sensitive river water level sensor to a heavy-duty deep well water level sensor, this device bridges the gap between simple mechanical gauges and complex digital monitoring systems. Its ability to serve as a versatile liquid level detector or level pressure sensor ensures that industries ranging from agriculture to urban infrastructure can rely on accurate, real-time pressure and level data for critical decision-making.

View Explosion-proof Pressure Sensor
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.

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.
veswe 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.
