Monitor Technologies uniquely provides the best solutions in level measurement and inventory management of powders and bulk solids.

The Flexar guided wave radar level sensor and/or transmitter doesn’t require field calibration or re-calibration. Also, it sets up easily by customer personnel without using of any special tools or training. Finally, Flexar units are for almost any application. They operate with process temperatures up to 392° F (200°C), and provide a variety of process connections. Also, they work reliably with materials having a wide range of bulk densities and dielectric constants. Flexar is available with a choice of two outputs.

The standard output is a “smart” interface for use with SiloTrack™ Version 3.5 PC-based inventory management software. This network-ready software provides a flexible graphical interface for up to 128 “smart” output sensors. In lieu of this “smart” output, an optional analog output is also available.

Non-Contact Radar Continuous Level Sensor

The RadarRight™ radar level instrument emits a microwave pulse from its antenna. It travels at the speed of light to the surface of the medium below. The time-of-flight of the pulse and its reflection back to the instrument location directly relates to the empty distance in the vessel and the material level. Furthermore, the output from the electronics continuously updates as the level of the material surface changes. The RadarRight radar level instrument uses the proven 26GHz as the transmitting frequency.

POINT LEVEL INDICATION

KA/KAX Rotary Paddle Level Switches

Monitor’s KA/KAX line of rotary paddle bin level indicators are the most reliable. They are rugged and economical point level control sensors available for detection of dry bulk materials. Also, these easy to install switches are proven performers for a wide variety of bulk materials. They use paddle switches to eliminate bin overflow and maintain a predetermined material level Also, they indicate plugging of conveyors and pneumatic lines, or provide any of a number of level control functions. Unlike many other available paddle units for bins and silos, Monitor’s paddle level indicators (sensores de nivel) incorporate a feature that automatically shuts off the motor of the unit. This occurs when the paddle is in a stalled position. Consequently, this both extends the life of the motor and minimizes maintenance.

TrueCap® MK2 & MK-2E Point Level Sensors

TrueCap RF capacitance sensors offer cost-effective point level monitoring with reliability you can count on. Monitor’s complete line, which features models MK-2 and MK-2e, provides you with the most affordable solution for your application. Monitor’s RF capacitance probes provide a high level of sensitivity, stability and durability. They are for powder and bulk solids applications, as well as liquid and slurry applications.

DustAlarm^Ò Broken Bag Dust Detectors

The DustAlarm Broken Bag Detector provides reliable and economical detection of leaks and filter failures in many powder and bulk solids industries. Also it successfully utilizes a wide variety of applications where detection of dust levels is critical. Reasons include safety, maintenance, equipment operation, plant efficiency and/or the environment. The DustAlarm measures the triboelectric effect to determine when particle emissions exceed acceptable levels.

Also the Dust Alarm Broken Bag Detector incorporates visual indications and a relay output. This maximizes its user-friendliness and automation capabilities. A reference point sets the sensitivity control adjustment, aided by the tri-color LED. The alarm point is set by an alarm level control adjustment. The relay output activates an alarm device or integrates into a control system. This enhances the overall operation of the dust collector.

SafePoint^Ò Self Validating Rotary Paddle Level Switches

The SafePoint self-validating bin level indicator from Monitor is the state-of-the-art in rotary paddle technology. It goes beyond traditional fail-safe sensor technology that only protects against power failure. Furthermore, the SafePoint bin monitor is the most reliable, rotary paddle point level control sensor available.

The SafePoint bin level switch provides the ultimate in performance wherever critical continuous operation must be ensured. It detects both material presence and its own operational status on a continuous basis.

Finally, the SafePoint level sensor monitors its electrical and mechanical operating condition. This makes the SafePoint a “truly” fail-safe, self-validating device.

Bin Aeration – Bin Aeration Air Pads

The Monitor air pad bin aerator is an aeration device that promotes the flow of dry bulk powders from a storage vessel.

The Air Pad continuously introduces air into the body of the dry powder. When a powder is first conveyed into a storage vessel it is actually a highly aerated mixture of air and particulate. So, in this state, the mixture flows quite readily. However, as the powder settles the solid particulate and air separate. As a result this decreases volume and increases bulk density. In this deaerated state, powders behave more like a single large solid structure rather than a fluid-like mixture. It replaces the naturally lost air, so the air to particulate mixture ratio is held. Therefore it maintains the fluid-like characteristic of the aerated powder.
