Pressure Transducers – Stevens Water

Reliable Water Level, Pressure & Temperature Monitoring for Groundwater and Surface Water Applications

The Pressure Transducers from Stevens Water (Smart PT Series) are advanced digital sensors designed for accurate water level, pressure, and temperature measurement in groundwater wells, surface water monitoring, tanks, reservoirs, and environmental applications. Built with a high-performance ceramic membrane pressure sensor, these transducers deliver highly accurate and stable results across a wide range of fluid level monitoring applications. They support both instantaneous measurements and advanced statistical monitoring, making them ideal for remote and long-term field deployments. The Smart PT series features a rugged 316L stainless steel housing, fully potted electronics, and IP68 protection for long-lasting underwater operation. Available in both vented and absolute pressure versions, the sensor compensates for barometric pressure variations and automatically adjusts for water temperature-density dependency, ensuring highly reliable readings even in harsh environmental conditions.

Key Features:

  • 💧 High-Accuracy Pressure & Water Level Measurement

    Provides pressure accuracy up to ±0.1% of full scale with depth measurement ranges from 2 meters to 200 meters, ensuring precise monitoring for groundwater and fluid level applications.

  • 📡 Digital SDI-12 / RS-485 / Modbus Output

    Supports SDI-12 Version 1.4, RS-485, and Modbus RTU communication, allowing seamless integration with data loggers, PLCs, and remote monitoring systems.

Key Features:

  • 🌡️ Integrated Temperature Compensation

    Includes built-in temperature monitoring with automatic water temperature-density compensation and local gravity correction for improved depth and pressure accuracy.

  • 🛡️ Rugged Submersible IP68 Design
