Product Details

Product introduction

WSS series bimetal thermometer is an on-site detection instrument for measuring low and medium temperature. The bimetal thermometer can directly measure the temperature of liquid, steam and gaseous media in the range of -80℃~+500℃ in various production processes.

Working Principle

The industrial analog bimetallic thermometer uses a hot bimetallic piece wound in a threaded shape as a temperature sensing device, and it is installed in a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called Free end. There is a pointer on the free end spool. When the temperature changes, the free end of the temperature sensing device rotates accordingly, driving the pointer on the thin shaft to produce an angle change, and indicating the corresponding temperature on the dial.

Selection instructions

According to the connection direction of the bimetal thermometer dial and the protective tube, the bimetal thermometer can be divided into four types: axial type, radial type, 135°direction type and universal type.

①Axial type bimetal thermometer: The pointer plate is connected vertically with the protection tube.

②Radial type bimetal thermometer: The pointer disc is connected in parallel with the protection tube.

③135°direction bimetallic thermometer: the pointer disc and the protection tube are connected at 135°.

④Universal bimetal thermometer: The connection angle between the pointer plate and the protective tube can be adjusted at will.

Fixed form

In order to meet the needs of actual production, bimetal thermometers have different installation and fixing forms: movable external threaded pipe joints, movable internal threaded pipe joints, fixed threaded joints, ferrule threaded joints, ferrule flange joints and fixed flanges.

For example,WSS-401 Industrial bimetal thermometer is with 100mm dial diameter, back connection, fixed thread and SS304 probe.
