The Setra 268 Series Micro Differential Pressure Transmitter is a high-performance instrument built on Setra's unique variable capacitance sensing technology. It features a stainless steel diaphragm and a fixed electrode, where pressure changes alter the capacitance value, which is then converted into a linear DC signal via a specialized detection circuit.

With a minimum measurement range of 0~25Pa and a maximum of 0~25KPa, it offers reliable pressure measurement for differential or gauge (static) pressure, outputting a proportional 4-20mA current signal with a 24VDC excitation voltage. Its excellent performance-to-price ratio makes it widely applicable in various industrial fields.

• Variable Capacitance Sensing: Utilizes SETRA's proprietary variable capacitance sensing technology for accurate and stable pressure measurement.
• Durable Construction: Stainless steel subarc welding sensitive element ensures robustness, and the elastic diaphragm can withstand 70KPa overpressure (positive/negative) without damage.
• Temperature Compensation: Equipped with a temperature compensation circuit, the temperature influence is less than ±0.06%FS/°C within the 5~65°C range, ensuring stable performance across varying temperatures.
• Multiple Accuracy Options: Standard accuracy is ±1%FS at room temperature, with optional higher accuracies of ±0.4% and ±0.25%FS to meet more demanding applications.
• On-Site Range Selection: Offers 6 on-site optional ranges, providing flexibility to adapt to different measurement requirements.
• Cast Aluminum Housing: The cast aluminum housing enhances durability and protection, suitable for various industrial environments.
