Description：
Productoverview:
WSS seriesHealth type double metal thermometerUsually used in food, general health food factory special type double metal thermometer based on the chuck, around to the bending of sheet metal forming, if in the process of using one end of heat expansion drives the pointer to rotate, instrument shows the temperature value should be.Double metal thermometer has the display characteristics of temperature and is convenient, safe and reliable, long life and other advantages, of course, a variety of forms to meet the different needs of users.
Two, work principle:
WSS series <strong style="white-space: normal;"> sanitary type double metal thermometer</strong> is based around the ring made of bent double sheet metal.At the end of heating expansion, drives the pointer to rotate, the instrument will display the temperature value.
Thermal sleeve type double metal thermometer is usually made of sheet metals of spiral shape.When the multilayer metal sheet temperature changes, each layer of metal expansion or shrinkage range, so that the spiral rolled up or loosen.Since the end of the spiral coil is fixed and the other end and a pointer can rotate freely. Therefore, when the feeling of double sheet metal to temperature changes, in a pointer to the circular indexing on the gauge indicates the temperature to.
Three, application:
WSS series <strong style="white-space: normal;"> sanitary type double metal thermometer</strong> to meet the drug production quality specification (GMP) requirements, the appropriate health system, in which medium can not be in contact with instrument measurement system.Sanitary clamp seal does not produce dead or not emptying the area, this thermometer has convenient assembly and disassembly, easy pollution, easy cleaning, beautiful appearance, safe and reliable performance and other advantages, can be widely used in pharmaceutical, food, beverage, dairy, water treatment and other industries.
Four, main features:
The scene temperature display, intuitive and convenient; safe and reliable, long service life;
A variety of forms, can satisfy different requirements.
Five, technical parameters:
