ControlAir Inc. announces the introduction of the Type- 590X I/P Transducer. This unique current-to-pressure transducer is small in size and light weight, yet is less sensitive to shock vibration and position change than most other I/P’s. Conversion technology utilizing open loop control and a low mass magnet produces accurate pressure control at an economical cost. The Type-590X can mount in any position and is impervious to RFI/EMI interference. The Type-590X I/P transducer converts a variable electrical signal to a linearly proportional pneumatic output. The small size allows for dense mounting in panels, can mount in any plane and is stable in high vibration environments. The Type-590X is approved by Factory Mutual (FM) and Canadian Standards Association (CSA) as intrinsically safe. It is also compliant with the ATEX directive 94/9/EC for equipment intended for use in potentially explosive atmospheres in Europe. Type-590X is ideal for process control valve positioner applications used in HVAC, chemical, petrochemical, oil and gas, pharmaceutical and food processing markets. Other OEM applications include printing presses, textile machinery, tire machinery, paper machinery and paint spray systems. Basic Specifications: - Porting – 1/8” NPT - Input signal – 4-20 mA - Output ranges – 3-15, 3-27, 6-30 psig - Maximum supply pressure – 22 psi (3-15 output), 42 psi (other outputs) - Flow capacity – 2.4 SCFM - Air consumption – 6 SCFH - A manifold version is also available for electro-pneumatic valve positioner applications.
