HK Instruments DPT-MOD-2500-D 差压变送器 (-250...2500 Pa; with display)

Measurement ranges (Pa): -250...2500 Pa

Communication: RS-485 Modbus (RTU)

Accuracy (from applied pressure): Pressure < 125 Pa = 1 % + ±2 Pa; Pressure > 125 Pa = 1 % + ±1 Pa

Zero point calibration: automatic with autozero element (-AZ), by pushbutton or via Modbus

Measuring units: Pressure: Pa, kPa, mbar, inchWC, mmWC, psi;  Flow: m3/s, m3/hr, cfm, l/s, m/s, ft/min

Measuring element: MEMS, no flow-through

Supply voltage: 24 VAC ±10 % / 24 VDC ±10 %

Power consumption: < 1.3 W

Output signal: via Modbus

Response time: 1.0−20 s, selectable via menu or via Modbus

Operating temperature: -20…+50 °C (with autozero calibration -5...+50 °C)

Protection standard: IP54
