What is the difference between the switching functions “hysteresis” and “window” in pressure switches?
Electronic and mechanical switches are used for monitoring critical limit values and therefore usually fulfil a safety function. To meet this safety function, switches offer two alternative switching functions, the “hysteresis” and the “window” functions.In general, these two switching functions differ from each other in that the “hysteresis” function monitors a limit value and the […]
ABB UNVEILS FUTURE OF PROCESS AUTOMATION
ABB presents the method ahead for DCS as vital to sustainably assembly the rising demand for power, utilities and items ABB has released its White Paper entitled “The DCS of tomorrow: ABB’s process automation system vision,” which outlines how process automation systems will evolve to assist industries as they endure digital transformation and shift to […]
CAN bus problems with pressure sensors avoided: integrated Y-connector for harsh mobile hydraulics applications
CAN bus pressure sensors (CANopen® and J1939) for mobile hydraulics applications now offers an integrated Y-connector – an electrical connection that provides ruggedness and can survive in the hostile environment of trucks, cranes, excavators or agricultural equipment.When it comes to pressure sensors in mobile hydraulics applications their robustness and resistance to dirt, moisture and really […]
What is salinity meter and the way does it work?
What is a salinity meter? A salinity meter is a tool used to measure the salt content material in a substance. It is an easy-to-use water quality indicator device and is an efficient approach to shortly estimate dissolved salt in varied water samples.They can be used for a variety of applications, including testing salinity levels […]
Hot water circulate meter
There are two measurement alternatives in heated hot water purposes; scorching water output leaving the plant and sub-metering opportunities on the receiving finish. apure presents a variety of scorching water flow meter technologies which are notably properly suited for this challenging application. Some issues for drive know-how selection embrace installation necessities, accuracy requirements and upkeep […]
Load pins: Definition and application areas
A load pin provides the connection between force-transmitting machine elements and also allows the simultaneous measurement of the force acting on the sensor. The load pins are fixed in the axial direction as well as against rotation. A small gap of about one fifth of a millimeter between the axle retainer and the slot ensures […]
Cleaning of submersible pressure transmitters or level probes
If ไดอะแฟรม ซีล of the submersible pressure transmitter or level probe is selected to gauge the filling levels, this often means that the probe is used under environmental requirements which may cause failure of common level sensors.The most unfortunate circumstances such as for example soiled media, abrasive ingredients and sludge when found in wastewater treatment […]
Five explanations why force measurement is important
WIKA has been an internationally recognised partner for all measurement tasks for many decades. The product portfolio includes pressure, temperature, force and level measurement, together with flow measurement, calibration and SF6 gas solutions. In the next article, we wish to take a closer consider the measured variable of force. These five reasons show why force […]
Two chlorine sensor measuring principle
Residual chlorine sensors are based on different measuring principles, can be divided into diaphragm polarographic sensor and fixed voltage sensor.Used for steady monitoring of residual chlorine.diaphragm polarographic sensor, cathode, anode, electrolyte and cathode lined with a layer of gasoline permeable skinny film composition. The remaining chlorine within the tested answer diffuses to the cathode via […]
Diaphragm seal system detects level in PTA reactors
Diaphragm seal systems are ideal for many processes in the chemical industry as a resistant and safe measuring solution, for example, to monitor the level in a reactor using differential pressure. Precisely for this task, a manufacturer of terephthalic acid (Purified Terephthalic Acid, PTA) uses such a measuring arrangement with an integrated differential pressure transmitter. […]
