Monitoring Wood Dust/Shavings in Dust Collection System

Many processes of bulk solid materials require dust collection to keep production areas safe and clean as well as to reclaim material.  Dust collection systems are commonly used in these situations.  In a wood working system a dust collection system was manufactured using a 55 gallon drum as the collector.  To keep the drum from overfilling and to prevent the dust from backing up into the system, a compact rotary paddle bin level indicator has been successfully used.

Thermal Flow Switch Ensures Coolant Flow

Thermal flow switches have many uses.  Technically they operate using thermal dispersion technology.  They are solidstate sensors without any moving parts, which is one of their benefits.  The detect flow / no-flow conditions for a wide variety of reasons including control.

Rotary Paddle

Rotary paddle bin level switches have been in use since at least the mid-1930’s.  Today the rotary paddle technology are some of the most state-of-the-art and capable point level sensors or level switches.  The rotary paddle is now available in a compact form, making the compact rotary paddle bin level switch ideal for some of the smallest hoppers in use.  This is particularly true for plastic processing machines.

EE300 Inventory Sensor System Monitors Inventory

Often times electromechanical inventory measuring systems do not deliver what you need.  But the EE300 series from Aplus Finetek does indeed provide you the information you need, in the format you need it.  The EE300 is a weight & cable inventory sensor for bulk solid materials, such as plastic pellets, cement powder and many other stuff.  Combined with the MMS materials management software you can access as graphic and data from almost anywhere.  It is also known as a plumb-bob, yo-yo or bin bob type of device.

Float Level Transmitter

There are two primary categories of level measurement, i.e. Point Level and Continuous Level measurement.  Most units sold fall into the first category, point level.  However it is the continuous level category that provides the greatest amount of information and usually that means a higher cost of purchase.  In the area of continuous level measurement of liquids there are several types of sensors that can be used.  One of the most common of the types of continuous level transmitters are the float level transmitter.  These devices use the principle of buoyancy as one of the primary means to determine the level of a fluid as it changes on a continuous basis, hence the name float level transmitter.  There are two types of float level transmitter units, we explain them both in this post.

Thermal Dispersion Flow Switch

SP series thermal dispersion flow switch

SP series thermal dispersion flow switch detects flow of seawater for engine cooling – Marine use

A thermal dispersion flow switch is a solidstate flow switch with no moving parts. It can be used for monitoring flow/no-flow conditions of a very wide range of liquids. The thermal dispersion flow switch can be provided with solidstate or relay output. They are relatively compact and can be applied in a range of pipe sizes. All stainless steel construction, a variety of process connection sizes are provided. The Thermal dispersion flow switch is available for general purpose and explosionproof environments.

RF Admittance Level Transmitter

EB5 ON PLASTICS SILO

EB5 Series RF Admittance Level Transmitter – Plastics

Measuring levels of liquid and bulk solids is commonplace and can be done for control or inventory purposes.  Numerous technologies are available for measuring liquid levels including magnetic float, magnetostrictive, hydrostatic, radar, TDR and electromechanical devices.  However, an overlooked technology that can be used for measuring both liquid and bulk solids level exists and is often the least expensive approach, for bulk solids, and that is the RF admittance level transmitter.

Thermal Flow Switch

There are many applications where knowing whether there is flow or no-flow conditions of a fluid in a pipe is important.  A thermal flow switch is an option to consider to provide such positive indication of flow or no-flow conditions.  Detecting flow conditions also can be accomplished using a electromechanical paddle type flow switch.  However, a thermal flow switch operates without any moving parts and therefore is more reliable.

Optical Level Switch

The optical level switch has many uses, especially in a wide range of machines to determine high or low levels of various fluids.  The advantages of an optical level switch typically include their compact size, high reliability and relatively low cost.  However, using the optical level switch is for liquids only, typically clean liquids.  From a control standpoint most optical level switch units provide solidstate transistor type outputs, TTL, NPN and PNP.
