APZ 3420 m
8Pages

PRESSURE TRANSMITTER WITH FLUSH DIAPHRAGM FOR VISCOUS MEDIA DESCRIPTION APZ 3420 m is a flush diaphragm version of our standard pressure transmitter. Due to it’s optimized design, it does not have dead zones that can get blocked by the viscous and pasty media. Optionally, APZ 3420 m can be equipped with a heat sink element for high temperature media applications. SPECIFICATIONS Pressure ranges: 100 mbar up to 600 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: G1/2”; G1/4”; 1/2” NPT; 1/4” NPT; М20х1.5 etc. Media temperatures: -40…+125 °C Optional: field housing with/without graphics display Optional: heat sink for media up to 300 °C APPLICATIONS General industrial applications Process automation Viscous liquid level monitoring Industrial machinery Hydraulics Appearance, mounting kit contents and/or specifications are subject to change without prior notice. We are constantly working on further improvement of our products. Delivery is subject to standard terms of delivery. © 2020 Piezus Page 1. Version: 11.0 Date: 20.05
