APZ 3230
8Pages

PRESSURE TRANSMITTER FOR VERY LOW PRESSURES AND VACUUM DESCRIPTION APZ 3230 is based on a silicon piezoresistive sensor without media isolation diaphragm and therefore is capable of measuring very low pressures and vacuum. Compatible with non-aggressive and non-corrosive gases and low viscosity oils, APZ 3230 has a great long term stability and reduced temperature error comparing to the traditional models with diaphragms. Dry sensor makes this model preferable in applications where media contamination with filling oil is not desirable. SPECIFICATIONS Pressure ranges: 6 mbar up to 1 bar 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, no media isolation Pressure port: G1/2”; G1/4”; 1/2” NPT; 1/4” NPT; М20х1.5 etc. Media temperatures: -40…+90 °C Optional: field housing with/without graphics display APPLICATIONS Medical equipment Laboratory instruments Clean rooms HVAC Vacuum applications Appearance, mounting kit contents and/or specifications are subject to change without prior notice.
