Available in a wide variety of gauge pressure ranges, the 256 also features adjustable potentiometers for zero and span settings. Only 3.6” high x 4.0” wide, the Model 256 is designed for compact installations. The removable cover provides easy access to the internal terminal strip for wiring. Installation is quick and easy with 1/2 inch internal threaded conduit ports for electrical termination. NOTE: Setra quality standards are based on ANSI-Z540-1. The calibration of this product is NIST traceable. U.S. Patent nos. 3859575, 4054833 Setra’s Model 256 industrial pressure transducer is one of the most rugged and reliable sensors available. The Model 256 is packaged in a die-cast aluminum enclosure that is specifically designed for NEMA4/IP65 service. Setra’s robust capacitive design is resistant to environmental effects, such as shock, vibration, temperature and EMI/RFI. Superior mechanical and thermal stability is achieved through Setra’s patented variable capacitance sensor. Its fundamentally simple design features an insulated electrode plate in close proximity to the sensor diaphragm, which forms a variable capacitor. As pressure increases or decreases, the capacitance changes. This change When it comes to a product to rely on - choose the Model 256. When it comes to a company to trust - choose Setra - an ESOP (Employee Owned) Company.
