Product catalog summary
Overview: The Point™ Two-Wire RF Series Point Level Switch is designed for detecting the presence or absence of liquids, slurries, and granular materials without requiring calibration or setpoint adjustments. It is suitable for high-pressure and high-temperature environments.
Key Features:
  • No need for calibration or setpoint adjustments.
  • Automatically ignores changes in dielectric or conductivity and recognizes coatings to prevent false alarms.
  • Economical with superior performance and minimal maintenance due to the absence of moving parts.
Specifications:
  • Technology: RF Admittance
  • Calibration: None
  • Modes of Operation: High and Low Level
  • Repeatability: 2 mm for conductive liquids
  • Response Time: Less than one second
  • Temperature Range: -40 to 70°C for ambient electronics, -40 to 85°C for storage
  • Indicators: Green Power LED, Red Alarm LED
  • Time Delay: 0-60 seconds, forward or reverse-acting
  • Supply Voltage: 13-30 VDC
  • Power Consumption: 2 watts maximum
  • Output: Configurable as 8mA (Alarm), 16mA (Normal) or vice versa
  • Housing: Powder-coated aluminum with IP66 NEMA 4X ingress protection
Approvals: The device is explosion-proof and dust ignition-proof, suitable for various hazardous locations as per specified standards.
Applications: Suitable for general-purpose to high-pressure and high-temperature environments, including corrosive and granular materials, and sanitary conditions.
Installation and Maintenance: Easy to install with minimal maintenance. The sensor length can be adjusted in the field, and electronics can be remotely mounted for convenience and safety.
Additional Specifications:
  • Pressure and Temperature Ratings: Sensors rated for different pressure and temperature combinations, such as 9 bar at 38°C and 34.5 bar at 149°C, using materials like 316SS and TFE.
  • Materials: Includes 316SS, TFE, 304 SS, Neoprene, and Ceramic, selected based on application needs.
Procedures:
  • Installation: Sensors available for remote installation with specific pressure and temperature ratings, suitable for applications like hopper installations and plugged chute detection.
  • Mounting Options: Includes NPT threads, sanitary TriClamps, ANSI flanges, and DIN flanges, with specific configurations for each type.
Standards and Approvals:
  • Approvals: Sensors have FM, FMc, ATEX, and IECEx approvals, ensuring compliance with industry standards.
  • Protection Ratings: NEMA 4X/IP66 ratings provide protection against environmental factors.
Recommendations:
  • Select appropriate materials and configurations based on the specific application environment and requirements.
  • Ensure compliance with relevant standards and approvals for safety and reliability.
Key Data from Tables:
  • Pressure/Temperature Ratings: Detailed for each sensor type, indicating suitability for specific industrial conditions.
  • Mounting Configurations: Various options are provided, including remote electronics and different cable lengths.

PNL Series, ThePoint, Loop Powered-1

DATA SHEET Intelligent Electronics Save Time and Money • UNIQUE! - NO calibration or setpoint adjustments. • UNIQUE! - Ignores changes in dielectric or conductivity. • Automatically recognizes and ignores coatings to prevent false alarms. Diverse Applications • Detects the absence or presence of liquids, slurries, and granulars. • Capable of high pressures and temperatures. Economical Without Sacrifice • Retains superior performance. • Less maintenance than other technologies; no moving parts to hang up or wear out. Output • 8mA (Alarm), 16mA (Normal) or • 8mA (Normal), 16mA (Alarm) One of the Drexelbrook RF Point Level Switches You Won't Have to Calibrate Simply install ThePoint Series into the tank and apply power...that's it! Unlike other RF or capacitance systems that require calibration via setpoint potentiometers, jumpers, magnets, or pushbuttons, ThePoint Series reliably detects the absence or presence of material without any adjustments. ThePoint Series software continuously monitors the application for changes in composition, dielectric or conductivity, and maintains a repeatable trip point on the probe. Other RF and capacitance systems require calibration adjustments when the process material is changed. Since ThePoint Series recognizes changes in material, it is ideal for non-dedicated tanks that are used for a wide variety of products. Lower Cost of Ownership In addition to lower initial investment, ThePoint continues to save with little or no maintenance compared with other technologies. Further, the sensor can be lengthened or shortened in the field, saving need for additional purchases. Remote or Integral Electronics Unlike many technologies, electronics can be remote mounted to a convenient or safe location.
