This is a high - performance pressure switch, model RT1A. It is widely applicable in various industrial scenarios. 1. Pressure - related Parameters The adjustment range of the pressure switch is -0.8 to 5 bar (Pe), which can also be expressed as 23.6 inHg - 72.5 psig. This wide adjustment range allows it to meet different pressure control requirements. The hysteresis range is 1.3 - 2.4 bar (equivalent to 18.9 - 34.8 psi), ensuring stable and reliable pressure control. The maximum test pressure [bar] Pe is 25 bar, and the maximum test pressure [psig] is 363 psig. The highest working pressure [bar] is 22 bar, and the highest working pressure [psig] is 320 psig. These values indicate the pressure - bearing capacity of the product, ensuring its safety and durability during operation. The pressure connection size is 3/8, with a connection type of G, and the connection standard is ISO 228 - 1. The pressure connection note is that a welded reducing pipe of 6.5/D10mm is required. The pressure connection has male threads. The pressure - sensing element is a bellows, which is sensitive to pressure changes. 2. Electrical Parameters The electrical connection is in the form of a cable thread connection, with a size of 2xPg 13.5 and a female - threaded connection form. The electrical connection standard is DIN 40430. The electrical specifications comply with EN 60947 - 4/-5. The wiring properties include flexible with ferrules (0.2 - 1.5 mm²), flexible without ferrules (0.2 - 2.5 mm²), and solid / stranded (0.2 - 2.5 mm²). The electrical insulation is 400V, the pollution level is 3, the rated impulse voltage is 4 kV, and the short - circuit protection uses a 10A fuse. The contact function is SPDT (Single - Pole Double - Throw), and the contact capacity is as follows: AC15 = 3 A, 400 V; AC1 = 10 A, 400 V; AC3 = 4 A, 400 V; DC13 = 12 W, 220 V; LR = 28 A, 400 V. 3. Protection and Environmental Parameters The enclosure protection level is IP66, which provides excellent protection against dust and water, ensuring stable operation in harsh environments. The blasting pressure [bar] is 88 bar, which reflects the product's ability to withstand extreme pressure. The environmental temperature range is -50 °C (the lowest) to 70 °C (the highest), which is equivalent to -58 °F (the lowest) to 158 °F (the highest). This wide temperature range allows the product to be used in different climates and working conditions. 4. Others The product is repairable, and the repairable part is the contact system. It also has a reset function, which is automatic. The product has passed multiple approvals such as CCC, CE, EAC, and RoHS, which guarantees its quality and compliance with relevant standards.
