Type 500 - Electropneumatic Transducer (I/P, E/P)

Product catalog summary

Overview: The Type 500X Electropneumatic Transducer by ControlAir is designed to convert electrical signals (current or voltage) into proportional pneumatic output pressure. It is suitable for applications requiring high reliability and repeatability at a low cost, with optional NEMA 4X (IP65) for outdoor use.

Applications: Commonly used in industries such as petrochemical, HVAC, energy management, textile, paper, food, and drug for controlling valve actuators, pneumatic valve positioners, dampers, louvers, relays, air cylinders, clutches, and brakes.

Features: Key features include low cost, integral volume booster, compact size, low air consumption, field reversibility, flexible zero and span adjustments, standard process inputs, and split ranging capabilities.

Specifications: The Type 500X is available in two versions: a lower range model for 3 to 15 psig output and an extended range model for up to 120 psig output. It operates on a force balance principle with a coil and magnet system. The unit is field reversible and can be recalibrated for split ranging.

Installation and Safety: The transducer can be mounted via pipe, panel, or bracket. It is Factory Mutual approved as intrinsically safe and nonincendive for various classes and divisions. Installation should follow ControlAir's guidelines for safety and performance.

Performance: The transducer offers high repeatability (<0.5% of span), low hysteresis (<1.0% of span), and quick response time (typically <0.25 sec for 3-15 psig units). It consumes minimal air and supports a wide operating temperature range (-20°F to +140°F).

Ordering Information: Various models are available with different input and output ranges, impedance, and optional accessories like DIN connectors, NEMA 4X enclosures, BSP porting, and pressure gauges.

Warranty: ControlAir provides an 18-month warranty against defects in materials and workmanship, with liability limited to repair, refund, or replacement.

Type 500 - Electropneumatic Transducer (I/P, E/P)-2

The Type 500X is available in two different versions. The lower range model is designed for standard process control applications which typically utilize a 3 to 15 psig output. The extended range unit provides up to 120 psig output for higher pressure industrial pneumatic and process control system requirements. Principle of Operation The Type 500X Transducer is a force balance device in which a coil is suspended in the field of a magnet by a flexure. Current flowing through the coil generates axial movement of the coil and flexure. The flexure moves towards the nozzle and creates back pressure...
