US UE pressure switch H121-15875 Stainless steel piston H121 pressure switch selection features H121 type, single point switch, externally adjustable, with reference scale, one electrical interface, dead zone adjustableMaximum pressure: the switch can be continuous under this maximum pressure Work normally without damaging the components and keep the repeatability unchanged;Pressure resistance: Occasional occurrence of this maximum pressure will not cause permanent deformation of the components, but the switch needs to be re-calibrated; UE pressure switch X selection notes: 1. Explosion-proof Necessity: Explosion-proof forms are divided into flameproof type and intrinsically safe type. 2. Do you need to bring instructions: according to customer instructions. 3. Number of contacts: one contact (one output) or two contacts (two outputs). 4. Determination of setting value and pressure range: the recommended setting range is between 30% and 65% of the pressure range, and the settable range is between 15% and 90% of the pressure range. 5. The form of connection difference: adjustable or fixed. 6. Whether there is pulsation: If the pressure pulsates or vibrates, a throttle valve is required to suppress the damage to the instrument caused by the pulsating pressure. 7. Occasions with a diaphragm: When measuring corrosiveness, high viscosity or high temperature, it is necessary to use a diaphragm
