SISCO transducer uses a flush corrugated diaphragm to reduce material accumulation around the pressure-sensing surface. It is available with threaded and tri-clamp connections for different installation requirements and supports gauge, absolute, and sealed gauge pressure measurement. With multiple output signals, IP65 protection, and media temperature capability from -30°C to +105°C.
- Flush Diaphragm & Corrugated Membrane Design: This diaphragm pressure transducer adopts a corrugated flush diaphragm to directly capture pressure signals. Its large contact surface greatly reduces scaling buildup, supports stable measurement of high-viscosity fluids, and prevents blockages from sludge and sticky media.
- Digital Circuit Board with Superior Anti‑Interference Capacity: Equipped with a digital PCB that complies with EFT Level 3A standard. It provides robust protection against surge and pulse interference, ensuring steady operation in complex industrial environments.
- Clog‑Resistant Structure Without Pressure Lead Hole: Engineered with no pressure guiding hole, this flush diaphragm pressure transmitter maintains accurate readings for liquids mixed with solid impurities, making it well suited for working conditions with contaminated media.
- 316L Stainless Steel Construction: Constructed from 316L stainless steel, this diaphragm pressure sensor features outstanding corrosion and rust resistance for extended service life even in aggressive media.
- Venting Structure for Stable Zero Point: Special gas guide venting design keeps zero point stable and ensures consistent, precise pressure readings.
Applications
This sanitary diaphragm pressure transducer is compatible with media including water, weak acid, weak alkali and other fluids suitable for 316L stainless steel. It is widely deployed across food, pharmaceutical, sanitary and brewing industries, capable of adapting to diverse working conditions.

Wiring Diagram
Q1: What is a diaphragm pressure transducer?
A1: A diaphragm pressure transducer is a pressure measurement device that uses a diaphragm to detect pressure changes and convert them into electrical signals.
Q2: What are the advantages of a flush diaphragm pressure transducer?
A2: A flush diaphragm pressure transducer features a sensing diaphragm that sits flush with the process connection, eliminating the need for a conventional pressure inlet hole. This design helps minimize clogging and material accumulation when measuring high-viscosity fluids, sludge, and contaminated liquids, supporting more stable pressure measurement in demanding industrial environments.
Q3: Is a diaphragm pressure transducer suitable for high-viscosity fluids?
A3: Yes. A flush diaphragm design is well suited to many high-viscosity fluids because it reduces narrow passages where thick materials can accumulate. It can be used in compatible viscous liquids, pastes, and other challenging media when the pressure range and temperature limits meet the process requirements.
Tips: How can I prevent measurement errors when using a diaphragm pressure transducer?
To prevent measurement errors when using a diaphragm pressure transducer, select the appropriate pressure range and pressure type, ensure the process media is compatible with the wetted materials, and follow the recommended installation procedures. Keep the flush diaphragm clean, verify power supply and output signal compatibility, minimize electrical interference, and perform regular calibration and maintenance to maintain reliable pressure readings.
