BELLOFRAM

Bellofram electro-pneumatic transducers in the 3G Electric catalog accept a 4–20 mA input signal and provide proportional pneumatic outputs. Nominal output ranges include 3–15 psig, 3–27 psig, 2–60 psig, and 3–120 psig. The specific range depends on the model; for example, MPN 961089000 provides 3–15 psig, while MPN 961111000 provides 3–120 psig. Output pressure is proportional to the input current, allowing the transducer to drive pneumatic actuators, valve positioners, and other final control elements. Selection should be based on the required output pressure and the actuator's signal range.

Bellofram transducers are available with bracket, DIN-rail, panel, or pipe mounting configurations. The mounting style is often specified by the model number and can be selected based on the installation environment. Bracket and panel mounting are common in control panels and cabinets, while pipe mounting is used when the transducer is installed directly on a pneumatic line. DIN-rail mounting allows for compact installation in electrical enclosures. 3G Electric lists the mounting type in the product specifications for each SKU, so buyers can verify compatibility before ordering.

Many Bellofram electro-pneumatic transducers carry CE, CSA, and FM listings. These certifications indicate compliance with applicable standards for industrial control equipment. However, certification alone does not determine suitability for a specific hazardous area classification. Buyers should verify the exact approval markings on the product data sheet and confirm they meet the requirements of the installation site. 3G Electric provides the standards information available for each SKU, and can assist with part-number selection when a specific approval is required.

A Bellofram electro-pneumatic transducer converts an electrical input signal, typically 4–20 mA, into a proportional pneumatic output pressure. It is used to interface electronic control systems with pneumatic actuators or valves. A Bellofram regulator, by contrast, is a mechanical device that maintains a set output pressure from a higher-pressure supply, independent of electrical signals. Regulators are used for pressure control in compressed air systems, while transducers are used for signal conversion in control loops. Both product families are available from 3G Electric, and selection depends on whether the application requires electrical signal conversion or mechanical pressure regulation.

Selection requires matching the input signal, output pressure range, mounting, and environmental ratings to the application. First, confirm the control signal available (e.g., 4–20 mA). Next, determine the required output pressure range based on the actuator or valve specification. Then check the mounting style and any area classification or certification requirements. Bellofram transducers are available in several output ranges, including 3–15 psig, 3–27 psig, 2–60 psig, and 3–120 psig. 3G Electric can provide specifications for each SKU and assist with cross-referencing existing part numbers.

Yes, 3G Electric ships Bellofram products globally. The catalog includes 68 Bellofram SKUs, primarily electro-pneumatic transducers and regulators. Orders can be placed for single units or larger quantities, and 3G Electric supports both new installations and replacement parts. For buyers outside Singapore, shipping and documentation are handled according to destination requirements. Technical specifications and part-number details are available for each listed product to assist with procurement.
