The Setra Model 256 is an ultra-rugged and reliable industrial gauge pressure transmitter engineered explicitly for high-performance process control, chemical processing, and environmental monitoring applications. Packaged in a compact, heavy-duty die-cast aluminum enclosure that complies with NEMA 4 / IP65 service standards, this durable instrument thrives under the most punishing physical constraints, including severe mechanical shock, high vibration, and intense EMI/RFI interference. Wetted fluid components are constructed from corrosive-resistant 17-4 PH stainless steel, enabling seamless, leak-tight integration across a broad spectrum of aggressive gases and liquid media. Utilizing Setra’s robust variable capacitance sensor design, the unit features built-in internal zero and span potentiometers for effortless field calibration trimming. Operating flexibly on low-cost, unregulated utility power lines, the Model 256 delivers simultaneous 4-20mA current loop or 0.1-5.1 VDC analog outputs via a removable terminal block connector and internal threaded conduit ports, ensuring ultimate wiring density and long-term signal fidelity in dynamic factory environments.
Key Product Features
