Benefits of Using Current Switches/Transformers

Motors are used for numerous industrial processes, be it moving air with a fan, pumping water with a pump, or driving a mechanical process. It is important to know when motors are not operating properly or require maintenance.

Many installations rely on a sensor or instrument used for the primary process, such as the use of a pressure transmitter to verify system pressure in a duct or the use of a flow transmitter to verify flow in a pipe. When errors or loss of pressure/flow are indicated, maintenance personnel may be dispatched to remedy the issue. However, this method does not indicate the root cause of an issue. Relying solely on primary process instrumentation opens the door to an unforeseen, possibly catastrophic situation. Continue reading “Benefits of Using Current Switches/Transformers”

The Operation of Gages and Switches in Hazardous Environments

In many industrial processes, the materials and the end product or by-products of the process, such as dust or vapors, can create conditions for a hazardous environment. Processes that have potential for hazardous environments include: water treatment, oil drilling, gas and chemical processing, power generation, pharmaceutical, and food manufacturing. The measurement and control of these processes are essential in maintaining optimal conditions of the manufacturing system and preventing catastrophic events.  Continue reading “The Operation of Gages and Switches in Hazardous Environments”

Thermal Dispersion Flow Switches

Thermal Dispersion Flow Switch, Series TDFS2

Dwyer Instruments, Inc. offers several flow measuring products that use a thermal sensing element.

Thermal dispersion flow sensors use a temperature element that is heated up beyond the media temperature. Based on calorimetry, the flow moving past the sensor will have a cooling effect that is directly proportional to the flow velocity. The heat is convected from the heated probe surface to the boundary layer of the fluid flowing over the heated surface. Continue reading “Thermal Dispersion Flow Switches”
