Sell pressure difference switch
Pressure difference switches are a type of switch that are used for protection in certain pressure conditions.
To achieve this, these devices have an initial value called the set point.
Filter pressure difference switch
If the value of the pressure difference between the two ends of a device reaches the setpoint, an output in the contact format will appear closed or open.
Usually, pressure difference switches open or close a 24-volt DC circuit when the circuit is activated, in which case the current in the circuit can vary from about 0.5 to 2 amps.
The best example to determine its function is a filter. If the filter becomes clogged, the signal will sound an alarm and notify the operator of the filter being cleaned or replaced.
Pressure switch price switch
Switches used in low-state protection conditions are normally open and switches used in high-state protection conditions are normally closed in order to detect circuit break (wire break) in these cases. .
Water pressure difference switch
According to the NAMUR standard, current switches can also be used for this equipment.
Depending on the conditions of the explosion environment, this equipment may be considered as Ex d or Ex I, and the sensors used for this switch can be selected as capacitive or diaphragm.
Installation of accessories such as 5-way manifold for this equipment is also required in the process.
Differential pressure difference switch
The concept of dead band is another concept that is considered in pressure difference switches.
This concept refers to the pressure difference between the setpoint where the pressure difference switch is activated and the pressure point at which the switch is reset.
For example, if the pressure difference switch with the setpoint point is considered 1 time and its dead band is 0.2 times and increasing, that is, when the switch reaches the point 1 time, we will have the contact and the contact will maintain its position up to 1.2 bar pressure. he does.
Honeywell pressure difference switch
When the pressure exceeds 1.2 bar, the switch will be in the position before the setpoint mode, and when installing this equipment, positive (high pressure) and negative (low pressure) bases should be considered so that no mistake is made in connecting the tubes to the equipment.
Also, to select these devices, the static pressure inserted on them should be considered.
Air pressure difference switch
In other words, if the low pressure base has a pressure of 40 bar and the high pressure base has a pressure of 42 bar and the device displays 2 times (pressure difference), if the valve of the low pressure base is closed for any reason and the total pressure is 42 The base high pressure load was placed on the device, the device can withstand this amount of static pressure.
