It can be adjusted using the Micro Adjustable option.
This microswitch incorporates a dial for proper adjustment of the differential or deadband. The option is the 1519 or the 1520 and is available on most devices.
Yes, it is possible.
United Electric Controls offers units with 2 or 3 independent set points for the 400 Series (Weatherproof IP65) and with two set points for the 120 Series (ATEX flameproof).
The Over Range Pressure is the pressure within which the pressure switch can operate without damage to the equipment or the need to make any adjustments.
The maximum working pressure (Proof Pressure) is the maximum pressure to which the equipment can be subjected, but adjustment may be necessary.
It is not necessary to indicate it.
All our units have a Normally Open contact (NO), a Normally Closed contact (NC) and a common contact (C).
With the Pressure Regulator we tend to keep the pressure adjusted downstream of the regulator. There is always more pressure upstream than downstream.
With the Back Pressure Regulator we ensure that there is no more pressure upstream of the regulator than the set pressure. It acts in a similar way to a safety valve, with much more precision and can also work permanently.
We have pressure regulators with venting or purge, especially indicated in processes where we must raise and lower the set pressure without the need for consumption in the line.
As well as non-vented pressure regulators, which are used when the gases or liquids to be regulated are toxic, corrosive or dangerous.
Yes, dual stage pressure regulators are available. With this type of pressure regulator, we guarantee that the outlet pressure will not increase as the inlet pressure to the regulator decreases.
This effect of increasing the outlet pressure occurs in single stage regulators. These are connected to a gas cylinder: as the cylinder is consumed, the inlet pressure decreases and the outlet pressure increases, without having changed the regulator setting.
They use both types, depending on the application.
On the one hand, diaphragm type sensors to work with pressures up to 35 bar output.
This type of sensor ensures greater accuracy and sensitivity, as well as virtually zero leakage.
On the other hand, they use piston-type sensors for pressures up to 700 bar.
This type guarantees a very long life cycle and a high degree of fatigue.
