流量开关（Flow switch）

Thermal conductivity FS-T thermal flow switch flow indicator

is designed based on the principle of heat exchange, probe the

built-in heating module and the heat sensing module, heat flow

indicator and the measured velocity is closely related to, if

not the medium flow pipe, heat heat received sense module is

a fixed value, and when the fluid medium through the flow

indicator probe, the heat sensing module receives heat and

change the flow velocity of medium, the heat sensing module the

temperature signal into electrical signal, then the signal

processor output into a 4 ~ 20mA signal and the corresponding

flow or set. The thermal flow indicator will be integrated flow

probe and signal processor integration, six LED lights provide

flow trend display, switching value can easily through the

front panel of the potentiometer adjustment screw protection,

and can provide a transistor, relay and analog output form.

The Gems piston type flow switch works on a fluid passage inside

the housing with a piston with a permanent magnet inside. When

the piston is pushed by the pressure difference caused by the

fluid flow, the magnetic piston will switch the sealing reed

of the equipment (the sealing reed can be SPST or SPDT, which

is related to the model of the product). The diameter of the

piston determines the starting flow. When the flow is reduced,

the stainless steel spring pushes the piston back. When the reed

switch is started, it can be transmitted by remote warning or

indication. Or you can integrate it into automatic control

In system.

Working principle：

Thermal conductivity flowmeter is designed based on the

principle of heat exchange. The probe is equipped with a heating

module and a heat sensitive module. The heat of the indicator

is closely related to the flow velocity of the fluid on the side.

If there is no medium flow pipe, heat heat received sense module

is a fixed value, and when the fluid medium flows through the

flow indicator probe, sense received thermal module heat

changes with the velocity of medium, the heat sensing module

and the temperature signal into electrical signal, then contact

signal processor the output is converted into the corresponding

4... 20mADC signal or set flow signal corresponding to the.

Combine TF series heat flow switch adopts digital circuit

design, the product adopts LED display, and uses advanced

magnetic ring rotating settings. High reliable design,

advanced digital circuit technology, which makes the product

anti-interference ability, high measurement accuracy,

stability. The full instrument IP65 is constructed with

stainless steel housing so that the instrument can be used in

any industrial environment.
