The Setra 230 is an advanced differential pressure transducer specifically designed to precisely monitor differential pressure in wet applications. Unlike other products that rely on two separate pressure sensors, the Setra 230 features a single diaphragm design, ensuring accurate wet-to-wet differential pressure measurement with exceptional ±0.25% FS accuracy. Its stainless steel capacitive sensor guarantees high precision and delivers a linear analog output that is proportional to the pressure across a wide temperature range.

One notable advantage of the Setra 230 is its immunity to line pressure. Unlike dual differential pressure sensors that require separate measurements and comparisons to determine the differential pressure, the Setra 230’s single diaphragm design eliminates discrepancies caused by line pressure variations.

Moreover, the Setra 230 boasts an improved sensor response time, thanks to its all-stainless steel capacitive sensor. With a response time 20 times faster than liquid-filled sensors, it enables rapid and accurate pressure measurements.

To simplify installation and maintenance, the Setra 230 offers optional 3-valve or 5-valve machined brass manifolds. These manifolds streamline the installation process, saving on project costs. Additionally, the brass body of the manifold eliminates the risk of internal leaks associated with internal pipe connections, ensuring reliable and consistent performance.
