Description
Specifications

Key Features

Potted electronics protect the signal circuitry from vibration, shock, humidity, and condensation
Excellent chemical resistance with probe materials in stainless steel, PPS, or optional PVDF
Operates independently of tank or pipe grounding, making it ideal for plastic or concrete vessels
Minimally affected by material buildup due to high-frequency oscillation
Three LED indicators display power, output status, and sensor condition
Complies with API 2350 for hazardous liquid storage applications

Typical Applications

Level detection in liquids, slurries, and foams
Detection of powders, granules, and bulk solids
Suitable for use in pressurized systems or hazardous environments
Effective in non-conductive tanks or pipes (e.g., plastic, concrete), no reference electrode required

Design and Operation

Galvanically isolated power supply, wide voltage range: 12 to 250 V AC/DC
Operates with media having a dielectric constant of 1.5 or higher
Configurable for pre-contact proximity detection or direct contact switching
When used with a thermal isolator, the wetted probe components withstand temperatures up to 125 °C (257 °F)
Fully compliant with EMC regulations, suitable for markets with strict electromagnetic compatibility standards
