Usage of Differential Pressure Transmitter in Cleanroom Application
Typically speaking, a cleanroom is constructed to establish a environment where containment of pollutant particles is controlled to low level. Cleanroom is extensively applicable in every industrial processes that impact of small particles needs to be eradicated, such as...Read more -
Introduction to Diaphragm Seal Connection for Transmitter
The diaphragm seal is a method of installation used to protect instruments from harsh process conditions. It acts as a mechanical isolator between process and instrument. The protection method is generally used with pressure and DP transmitters that connects them to the ...Read more -
Fundamental Pressure Definition and Common Pressure Units
Pressure is the amount of force exerted perpendicular to the surface of an object, per unit area. That is, P = F/A, from which it is obvious that smaller area of stress or stronger force reinforce applied pressure. Liquid/Fluid and gas can also apply pressure as well as...Read more -

Heat Sink Application in Instrumentation
Heat sinks are often used in electronic devices to dissipate heat energy away, cooling down the devices to moderate temperature. Heat sink fins are made of heat conductive metals and applied on high temperature device absorbing its heat energy and then emit to ambience v...Read more -
Accessories for Differential Pressure Transmitter
In normal operations, several accessories are commonly used to assist differential pressure transmitters in functioning properly. One of the vital accessory is valve manifold. The purpose of its application is to protect the sensor from single-side over pressuring damage and isolate the transmitt...Read more -
Why does 4~20mA 2-wire Become Mainstream Output of Transmitter
With respect to transmitter signal transmission in industrial automation applications, 4~20mA is one of the most common choice. In the case there will be a linear relationship between the process variable( pressure, level, temperature, etc.) and the current output. 4mA represents lower limit, 20m...Read more -
What is thermowell?
When using a temperature sensor/transmitter, the stem is inserted into the process container and exposed to the measured medium. In certain operating conditions, some factors could causing damage to the probe, such as suspended solid particles, extreme pressure, erosion,...Read more -
How does Display Controller Work as Secondary Instrument
An intelligent display controller could be one of the most common accessory instruments in process control automation. The function of a display, as one could easily imagine, is to provide visible readouts for signals output from a primary instrument (standard 4~20mA analog from a transmitter, et...Read more -
