DIFFERENTIAL PRESSURE TRANSMITTER FOR VENTILATION AND AIR CONDITIONING DESCRIPTION APZ 2030 is a HVAC/R pressure transmitter and switch. Large informative display provides measured pressure info in digital and bargraph form as well as units selected, and switch outputs status. With highly configurable independent two single pole double throw relay switch outputs, this small and cost efficient device is capable of local fans and filters monitoring as well as remote signal transmission via 4...20 mA or 0...10V analog outputs. SPECIFICATIONS Differential pressure ranges: 100 Pa up to 7 kPa Accuracy: ±1.5% Relay outputs: SPDT, 2 pcs Output: 0...10 V; 4...20 mA; Sensor: silicon piezoresistive Pressure port: barbed, for 4 mm ID tube Operating temperatures: -10...+50 °C Delivered with 2 meters of tube and 2 duct connectors APPLICATIONS For non-flamable and non-agressive gases Heating and ventilation Air conditioning Filters, fans, valves and air shutters monitoring Clean rooms 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: 20.05.2020
