Product Specification

SDX Analog Pressure Transducer DESCRIPTION
The SDX (Submersible Depth Transmitter) is a pressure sensor that delivers accurate results while still remaining very affordable for a wide range of level measurement applications.

High impact, corrosion-resistant PVC Type II housing and potted electronics make the SDX extremely durable for most water and hostile fluid environments. The SDX is also an excellent choice for level measurement application that may put more expensive sensors at risk for damage.

The SDX comes equipped with user specified vented cable lengths. The vent provides an atmospheric reference for the sensor, which is necessary for ensuring the highest possible accuracy when making a level measurement.

The SDX features one 4-20 mA analog output signal that corresponds linearly to range. Compatible with existing power and data logging instruments, the SDX can easily be deployed for data collection at remote monitoring sites.

The sensor housing integrates pipe threads for securely mounting the SDX into pipes, tanks, or other applications.

SDX Analog Pressure Transducer FEATURES
• Rugged housing and fully potted electronics—not damaged by freezing water
• Compact size
• Accuracy of ± 0.25% full span
• Analog output (4-20 mA)
• Vented cable, 2 wire, with drain
• Weighted copper nose cone

SDX Analog Pressure Transducer APPLICATIONS
• Well Monitoring
• Ground water monitoring
• Surface water monitoring
• Tank level monitoring
• Soil & ground water remediation
• Lake, river, and wetland studies
• Environmental impact and research studies
• Water level for flow calculations
