When the pressure drops to or rises to the rated recovery value, the disc resets instantaneously, and the switch automatically resets. In simpler terms, when the measured pressure exceeds the rated value, the free end of the elastic element displaces, directly or after comparison, pushing the switch element to change its on/off state, thus controlling the measured pressure. Pressure switches utilize elastic elements such as single-turn Bourdon tubes, diaphragms, capsules, and bellows. SOR product characteristics: SOR has won strong customer support for its diverse products, high quality, and excellent after-sales service, making them Widely used in industries such as power, oil and gas, chemical, water treatment, papermaking, and metallurgy. Since 1997, SOR switches have consistently held a leading market share in China's process industries, especially the power sector, establishing a strong sales force and a comprehensive after-sales service network. SOR pressure classification switches: Available in standard pressure switches, vacuum switches, sealed electrical unit switches, double setpoint switches, and adjustable differential switches. ■ Maximum operating pressure: 700 bar ■ Standard product temperature rating: 204 °C (higher temperature requirements can be achieved with a condenser coil) ■ Adjustable pressure setpoint range: Pressure switches 1.5 mbar - 480 bar;
- Vacuum switches 100 mbar - 5.5 bar. SOR mechanical pressure switches utilize pure mechanical deformation to activate the microswitch. When pressure increases, different pressure sensing elements (diaphragm, bellows, piston) deform and move upwards. This movement, via a lever spring and other mechanical structures, activates a microswitch at the top, resulting in an electrical signal output. SOR explosion-proof pressure switches are available in explosion-proof and flameproof versions, with usage levels ranging from Exd II CT1 to T6. Imported explosion-proof pressure switches require international certifications such as UL, CSA, and CE. They can be used in explosive areas and highly corrosive atmospheres. Explosion-proof pressure switches are available in various pressure, differential pressure, vacuum, and temperature ranges. Common applications include power, petroleum, chemical, metallic, boiler, food machinery, and equipment industries. SOR Company Profile: SOR Corporation of the United States primarily produces pressure, differential pressure, temperature, flow, and level switches. All products adhere to ISO9001 quality standards and are divided into two main categories: standard and explosion-proof. Major certification bodies include UL (USA), CSA (Canada), ASS (Australia), JIS (Japan), and CENELEC (Europe). SOR's switching instruments mainly adopt a diaphragm piston structure, which features high pressure resistance, high temperature resistance, shock resistance, corrosion resistance, impact resistance, and small switching error. They are widely used in industries such as petroleum, chemical, power metallurgy, pharmaceutical, papermaking, food, and water treatment.
Plain language sourcing guide for 52NN-K116-N4-B1A SOR differential pressure switch (agent for SOR switches)
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
