This pressure switch, model RT6AEB with product code 017 - 513466, is a high - quality industrial device designed to meet a wide range of pressure - monitoring and control needs.
Pressure - related Parameters
The adjustment range of pressure (Pe) varies from a minimum of 10 bar to a maximum of 28 bar, corresponding to 145 psig to 406.1 psig. This flexibility allows users to precisely set the pressure thresholds according to their specific applications. The hysteresis is 1.5 bar (equivalent to 14.5 psi), which is crucial for maintaining stable switch operations. It prevents the switch from rapidly toggling due to small, insignificant pressure changes, ensuring reliable performance over time.
The maximum test pressure (Pe) is 38 bar (551 psig), indicating the highest pressure the switch can endure during testing procedures. Meanwhile, the highest working pressure is 34 bar (495 psig), representing the upper limit for normal, continuous operation. These values are essential for users to ensure the safe and proper use of the device within their systems.
The pressure connection size is 3/8, and it features a G - type connection with external threads (pressure male/female: external thread). The connection standard follows ISO 228 - 1, guaranteeing compatibility with a wide range of industrial piping and equipment. A welding reducing pipe of 6.5/D10mm is required for connection. The pressure sensing element is a bellows, which is highly sensitive to pressure variations, enabling accurate pressure measurements and reliable switching actions. The burst pressure of the switch is 136 bar, providing an extra layer of safety in case of unexpected pressure surges in the system. The fluid group is 1, which may be related to the switch's compatibility with certain types of fluids in the application.
Environmental Parameters
The enclosure protection class of this pressure switch is IP54. This rating ensures that the switch is protected against dust and water splashing from any direction. As a result, it can be safely used in various industrial environments, including those with potential exposure to dust, moisture, or splashing liquids.
The ambient temperature range for this product extends from - 20 °C (- 4 °F) at the lower end to 65 °C (149 °F) at the upper end. This wide temperature range makes the pressure switch suitable for use in different climates and industrial settings, whether it's a cold storage facility or a warm manufacturing plant.
Electrical Parameters
The electrical specifications of this pressure switch adhere to the EN 60947 - 4/-5 standards. The electrical connection is of a cable - threaded type, with a size of 2xPg 13.5 and an internal - thread connection form (electrical connection male/female: internal thread). It complies with the DIN 40430 standard, ensuring reliable electrical connections in industrial applications.
Regarding the EN 60947 wiring properties, for flexible wires with ferrules, the recommended wire cross - section ranges from 0.2 - 1.5 mm². For flexible wires without ferrules and for solid or stranded wires, the range is 0.2 - 2.5 mm². In terms of EN 60947 electrical properties, it has a heat insulation of 400V, a pollution degree of 3, a rated impulse voltage of 4 kV, and short - circuit protection with a 10A fuse.
The contact function of the switch is SPDT (Single Pole Double Throw) with gold - plated contacts. Gold - plated contacts offer excellent electrical conductivity and enhanced durability, reducing the risk of contact failures over time. The contact capacity is specified as Ci = 0.5 nF, Ii = 0.5 A, Li = 0.2 uH, Pi = 1 W, and Ui = 29 V, providing clear information about the electrical performance of the contacts.
The reset function is manual maximum, allowing users to manually reset the switch to its maximum setting when necessary. This can be useful in situations where the switch needs to be re - calibrated or when the system pressure has been adjusted.
The product has been approved by multiple certifications such as ATEX - Cat. 2 - Zone 1, CCC, CE, EAC, etc. These approvals demonstrate that the pressure switch meets strict international and regional safety and quality standards. The product is also repairable, specifically the contact system, which helps to extend the lifespan of the device and reduce overall maintenance costs. The catalog number is IV, which can be used for easy product identification and reference.
