进口射频导纳物位开关Floating Roof Tanks的详细资料

进口射频导纳物位开关Floating Roof Tanks 

Floating Roof Tanks - Spill Prevention

Overview

Specifically designed for Floating Roof Tanks (Internal and External roofs) with Flexible Sensing Element 700-0005-594

进口射频导纳物位开关Floating Roof Tanks 

  • Field Adjustable lengths from 1' to 18' (0.3 to 5.48 m) 12" to 216" (305mm to 5486 mm)
  • Wetted Parts: 316SS 3/4" NPT Mounting, 3/16" FEP insulated flexible and adjustable cable, Non-Sparking Brass Sensor.

Features:

  • Alarm trip points with any contact of internal or external roof.
  • Alarm trip points in "Sunken Roof" applications with less than 1" product.
  • One system will fit most floating roof tank application needs, reducing field spares.

Inligent Electronics

  • Meets API 2350 regulations.
  • For use in safety related systems with requirements for functional safety for SIL2 (SIL 3 with Redundant Switch) In accordance to IEC61508-2, Sec. 7.4.3.1 1999 (Conforms to SIL, FMEDA Requirements - Exida)
  • No calibration or setpoint adjustments.
  • Automatically recognizes and ignores coatings to prevent false alarms.
  • Continuous Self-Test monitors circuits and sensing elements for faults
  • Remote or Integral Electronics

Dual Compartment Housing
The dual compartment housing separates the customer wiring from the sensing element and operating circuits. The encapsulated power supply/terminal block design eliminates the� possibility of damage caused by moisture in the conduit.

Self-Test Feature
Automatic and Local or Remote Manual test functions ensure proper system operation.

Auto Verification
Each InliPoint is supplied with a continuous self-test feature that constantly monitors the integrity of not just the electronics, but the sensing element and interconnecting cable. If a fault is detected, the InliPoint Auto Verification feature alerts plant personnel.

 

Manual Certification
The InliPoint provides a method to manually test the entire system without removing the sensor from the tank. The Manual Certify Test checks that the Auto Verify circuits are operating and confirms the probe and cables are properly connected. The Manual Certify also allows the InliPoint electronics to sense changes in the probe that simulate contact with the media or a floating roof. This provides the user with a method to insure working performance without having to climb the tank. At the completion of the Certify test routine, the output is momentarily held in the alarm state so personnel can confirm that the control circuits connected to the Final Control Element are functioning properly.
