1. Real-Time Pressure Monitoring
The core function of the VT2/VT3 sensors is to continuously and accurately detect static or dynamic pressure in fluid systems (liquids, gases, vapors). The high-response time (≤1ms for dynamic pressure) ensures that sudden pressure changes (e.g., pressure spikes in hydraulic systems) are captured in real time, preventing equipment damage.
2. Overpressure Protection & Alarm
Built-In Overpressure Safety: The sensors are designed with an overpressure range of 200% FS (maximum working pressure), preventing permanent damage to the sensing element when pressure exceeds the rated value.
Configurable Alarm Thresholds: Users can set upper/lower pressure alarm thresholds via the control system. When pressure exceeds the threshold, the sensor triggers an alarm signal (e.g., high-pressure warning for pipeline systems), enabling proactive maintenance.
3. Temperature Compensation & Self-Diagnosis
Automatic Temperature Compensation: The integrated temperature sensor and compensation algorithm adjust the pressure measurement data in real time based on ambient temperature, eliminating measurement errors caused by temperature changes—critical for outdoor or high-temperature industrial applications.
Self-Diagnosis Function: The sensors continuously monitor their own operational status (e.g., circuit integrity, sensing element health). If a fault occurs (e.g., open circuit, short circuit), the sensor outputs a fault signal (e.g., 22mA for 4-20mA output), facilitating quick troubleshooting.
4. Data Logging & Remote Control (Digital Models)
For models with digital communication functions (RS485/MODBUS RTU):
Data Logging: The sensors can store historical pressure data (up to 10,000 data points) locally, allowing users to review pressure trends over time (e.g., daily pressure fluctuations in water supply pipelines) for performance analysis.
Remote Configuration & Control: Users can remotely adjust sensor parameters (e.g., measurement range, output type, alarm thresholds) via the control system, without on-site operation—saving time and labor costs for large-scale industrial facilities.
1. Industrial-Grade Precision
The VT2/VT3 pressure sensors deliver exceptional measurement accuracy with a total error band (TEB) of less than ±0.25% FS over the entire operating temperature range (-40°C to 125°C). This level of precision ensures reliable data output even in harsh industrial environments, eliminating deviations caused by temperature fluctuations and mechanical vibrations.
2. Robust Environmental Adaptability
Wide Temperature Tolerance: Operates stably from -40°C (low-temperature industrial zones) to 125°C (high-heat manufacturing processes), suitable for extreme temperature scenarios such as automotive engine bays and industrial furnaces.
Vibration & Shock Resistance: Complies with IEC 60068-2-6 (vibration) and IEC 60068-2-27 (shock) standards, withstanding up to 500g peak shock and 20g continuous vibration—ideal for heavy machinery and transportation applications.
Corrosion Protection: The sensor housing adopts 316L stainless steel, and the pressure interface features PTFE sealing, providing excellent resistance to corrosive media like oils, coolants, and industrial chemicals.
3. Long-Term Operational Reliability
Extended Service Life: Designed with a solid-state sensing element (no moving parts), the MTBF (Mean Time Between Failures) exceeds 1,000,000 hours, reducing maintenance frequency and operational costs.
Stable Drift Performance: Annual drift is controlled within ±0.1% FS, ensuring consistent measurement accuracy over 5+ years of continuous use without frequent recalibration.
4. Flexible Integration Capabilities
Multiple Output Signals: Supports industry-standard outputs, including 4-20mA analog signal, 0-5V/0-10V voltage signal, and digital signals (RS485/MODBUS RTU), compatible with most industrial control systems (PLC, DCS).
Compact & Versatile Design: With a miniaturized housing (diameter as small as 19mm) and multiple pressure interface options (G1/4, NPT1/4, M12x1), the sensors can be easily installed in space-constrained locations, such as pipeline manifolds and equipment cabins.
