Az-220b Series Electronic Analyze Balance Scale Range 0-220, Precision 0.1mg

Product introduction:

AZ-220B series electronic analyze balance weigh the sample by the electromagnetic gauge transducer, so it has the high precision, and high environment adjustability feature., At the same time having linear calibration, counting, unit converting,. on the base of AZ-220B series Technology, change the circuit to the VLSI  in 2007, then adding the function of automatic inside weight calibration structure to get better steady, and rapid reaction Installed with RS232C interface inside, the produces can be directly connected to computers and printers etc, this series balance can be used widely in medicine research, school, enterprise and institution units, road build  and country defense as the ideal precision measuring instrument.

Feature:

1  Artificial design, originative structure, handsome appearance, New generation of electromagnetic gauge transducer reliably guaranties the precision of the products. With many application programs, such as automatic fault detection, linear four point calibration, overloading protection and so on.

2 Large back-lighted LCD makes the operator more comfortable.
 

Function:

1  Multip functions guaranteee easy and reliable operation,including auto-counting,unit conversion(metric carat,gole ounce,etc,),stablility,full-scale faring,zero-memory,etc

2  Bilit-in RS232C output interface guarantees direct connection to external equipemnt such ascomputer and printer

3  Built-in lower weighing hook guarantees convenient use.

Fixed Tube Heat Exchanger

Fixed tube heat exchanger consists of tube bundle, tube plate, shell, head, folded plate, etc. Tube bundle ends fixed in the tube plate, the tube can be expanded (the inner hole of the tube with mechanical expansion, so that the tube wall from the inward to outward extrusion and fixed in the tube plate) or welded to the tube plate. The tube bundle is placed within the tube shell, with headers and flanges fixed at both ends. In this way, one fluid flows from the inside of the tube and the other from the outside. The space between the two heads and the tube plate is used to distribute or collect the fluids inside the tube. The two fluids do not mix with each other, but only exchange heat through the tube wall.

Advantages: simple and compact structure, high pressure resistance, low cost and easy to clean the tube side.

Disadvantages: Risk of blockage when the tube is damaged or needs to be replaced.

When the difference between the wall temperature of the tube bundle and the shell or the coefficient of linear expansion of the material is large, a large thermal stress will be generated in the shell and the tube bundle. A flexible compensation ring (also called expansion joint) should be installed on the shell to reduce the thermal stress.
