The VR-21 is EDM's standard piezoelectric driven vibration type point level switch, which has an insertion length of 7.37 inches. Its unique single-rod probe design with a sword-shaped blade prevents bridging of material, making it superior to typical
"tuning fork" designs by allowing material to easily flow by, preventing build up on the blade. It is suitable for both top and side mount applications and is ideal for a wide variety of dry and bulk powder materials including
extremely light, fluffy materials. The VR-21 has optional hazardous location approvals to CSA standards for Class II, Division I, Groups E, F, and G in the US and Canada.
It features three sensitivity adjustments – high for light and fluffy materials, medium, and low for heavier materials or materials that may tend to cling to the vibrating rod. It is easy to install, mounting to the
vessel via a standard 1-1/2 inch NPT mounting socket and requires no calibration. Features include a self-cleaning sensor, switch selectable high/low fail-safe, and an auto sensing power supply which can accommodate 20
– 250 volts AC/DC. Remote electronics via a point level alarm panel are available to alert to bin levels for four up to 24 individual sensors.
The CVR-600 is a compact vibrating rod that is ideal for small bins, hoppers, and feeders. Featuring an overall insertion length of just six inches, it is suitable for space-constrained applications. It can be mounted on the top or side of the bin for
high, medium and low level indications. It is easy to install, fitting through a standard one-inch NPT mounting socket and can be used in process temperatures up to 300oF.
It features three sensitivity adjustments – high for light and fluffy materials, medium, and low for heavier materials or materials that may tend to cling to the vibrating rod. It requires no calibration and features
a self-cleaning sensor, switch selectable high/low fail-safe, and an auto sensing power supply which can accommodate 20 – 250 volts AC/DC. Remote electronics via a point level alarm panel are available to alert to bin levels
for four up to 24 individual sensors.
The SHT or Super High Temperature vibrating rod series is built specifically for higher process temperatures up to 482°F (250°C). It features a standard insulation tube that insulates the electronics from excessive heat. It has a standard insertion length
of 7.24 inches for both top and side mount applications. It can be extended from 13 inches up to 13 feet using a rigid pipe extension for top mount applications where extra length is desired.
It has three sensitivity settings, does not require calibration, and can be used to detect extremely light, fluffy materials. It features EDM's unique stainless steel single "rod" probe design that prevents bridging
and build-up of material on the sensor. Other benefits includes a switch-selectable, high/low fail-safe and an auto sensing power supply compatible with 20 up to 250 volts AC/DC. Remote electronics – using EDM's point level
alarm panel – allow for readings from four up to 24 sensors from a single device.
The EDM Point Level Alarm Panel is designed to alert the user to vessel level conditions via a blinking LED light and an audible alarm, saving time and eliminating the need to manually inspect vessel levels. Level indicators – such as a diaphragm switch,
rotary paddle, tilt switch, capacitance probe or vibrating rod – are placed strategically at desired points in each vessel, enabling the user to be automatically notified when a bin reaches a full, partially full, or empty
level. The alarm panel can also be connected to an external horn or common alarm to provide alert status from a variety of locations throughout a facility.
Consolidating information at a convenient centralized location, the Point Level Alarm Panel is available with four to 24 vessel level indicator stations, making it capable of monitoring high and low status for two
to 12 separate vessels from a single panel. If desired, an alarm panel may be configured for more than two readings from a single vessel, such as to add a partially full status to be read from additional level indicators
placed at other points on a vessel.
