SANITARY PRESSURE TRANSMITTER WITH FLUSH DIAPHRAGM DESCRIPTION APZ 3420 s is a sanitary version of our standard pressure transmitter with the flush diaphragm . All- welded design and smooth surfaces ensure absence of zones for potential contaminants collection. Process connection options, taper socket with grooved union nut as per DIN 11851, clamping socket as per DIN 32676 provide for quick disconnection for diaphragm cleaning. Optionally, APZ 3420 s can be equipped with a heat sink element for high temperature media applications. SPECIFICATIONS Pressure ranges: 100 mbar up to 40 bar Basic accuracy: up to ±0.25% Outputs: 4...20 mA (option Ex ia); 0...20 mA; 0...10 V; 0...5 V; HART®; RS-485/Modbus RTU Sensor: silicon piezoresistive Pressure port: taper socket with groved union per as DIN 11851, clamping socket as per DIN 32676, Tri-Clamp (*) Fill fluid: Food grade oil, FDA approved (*) Media temperatures: -20…+125 °C Optional: field housing with/without graphics display Optional: heat sink APPLICATIONS Food and beverage plants Pharmaceutical plants Biotechnology industry Cosmetics manufacturing (*) upon request Appearance, mounting kit contents and/or specifications are subject to change without prior notice.
