Company News & Resource

Pressure transmitter is a device that converts pressure into pneumatic or electric signals for control and remote transmission. It transforms physical pressure parameters, such as gas or liquid, sensed by the pressure sensing element sensor into standard electrical signals (such as 4~20mADC), to be used for measurement, indication, and process regulation by secondary instruments like indicators, recorders, and regulators.
A zirconia oxygen analyzer is an instrument used for precise measurement of oxygen content in industrial processes. Its application is extensive, including in the petroleum and chemical industries for ethylene and aromatic hydrocarbon production, hydrocracking processes, inert gas reaction furnaces or vessels, argon or nitrogen purification, combustion control in boilers or incinerators, gas cylinder filling and packaging in gas plants, marine inert gas generators, carbon dioxide purity detection in the brewing industry, and in heat treatment industry furnaces, among others.
Control valves are generally composed of electric actuators or pneumatic actuators and valve bodies. Regulating valves belong to the category of throttling valve devices within the moving parts. Compared with detection elements, transmitters, and controllers, control valves need to continuously change the throttling valve's flow area during the control process to adapt to changes in load or operating conditions, thereby altering the control variables. Proper installation of control valves is crucial, as it affects valve control effectiveness and service life.
A pressure gauge refers to an instrument that utilizes an elastic element as a sensitive component to measure and indicate pressures higher than ambient pressure. It is widely applied and virtually ubiquitous across all industrial processes and scientific research fields. Pressure gauges can be found everywhere, including thermal power networks, oil and gas transmission, water and gas supply systems, and vehicle maintenance shops. Particularly in industrial process control and technical measurement processes, mechanical pressure gauges, due to their high mechanical strength and ease of production, have become increasingly prevalent. As a result, testing the quality of pressure gauges has become crucial.
Coriolis Mass flowmeter is a new type of flow measurement instrument developed by BCST based on the principle of Coriolis . It can directly measure the mass flow rate of fluid and the density of the medium in a closed pipeline. The mass flowmeter consists of two parts: flow measurement sensor and signal converter.
Thermal mass flowmeter is a type of flow meter that utilizes the change in temperature field generated when a fluid flows over an external heat source to measure the mass flow rate of the fluid. Alternatively, it measures the relationship between the energy required to heat the fluid to a certain temperature rise and the mass of the fluid to determine the mass flow rate of the fluid.
