Features and Benefits of the VRF II Level Switch;
Simple Installation
Bindicators VRF II series capacitance level probe has a quick and easy calibration system and has universal power, enabling quick installation and getting your system running with minimal downtime. This unit can accept either AC or DC power and is insensitive to polarity, meaning less complex wiring. The EZ-CAL II allows the user to attach the level switch to the vessel and immediately begin sensing material.
Sensitivity and Control
With adjustable time delay and sensitivity settings, the VRF II can be tailored to specific applications and material characteristics.
Test FOB
The FOB is a unique feature that can determine whether the unit if functioning properly without removing the cover; it can also be used to calibrate the VRF II. By being able to keep the unit in place and the cover on, the test FOB can help save on unnecessary maintenance costs and troubleshooting. This feature is only available with the Advanced VRF II level switches, but also works with the remote versions as well.
Pro Guard
When the VRF II senses a change in the state of the level of material, it triggers the alarm; however, sometimes due to the characteristics of the material, like being sticky or an extremely fine powder, material will begin to stick to the probe causing a false alarm. The VRF II level switch has been specifically designed to ignore these material build ups and only alarm when a change in level has been detected.
Remote Options
There are two installation options available for the VRF II; an integral unit which combines the probe and the electronics into one unit or the remote option, which separates the electronics away from the process. Remote units are often used to move the electronics (including indicators LED’s) to a more convenient location for easier access and quick status indication. The remote option may also be used to move the electronics away from environments with higher operating temperatures. The remote unit may be mounted up to 30m away from the probe.
Global Approvals
Bindicator’s VRF II level switch is available with UL approval (for both the US and Canada) and CE marking (electromagnetic compatibility and low voltage directives) for ordinary locations or explosion proof and dust ignition proof hazardous area ratings.
