Siemens QBM68.2500D Differential Pressure Sensor, 0–2500 Pa

Precision differential pressure sensor for air and non-aggressive gas systems

Overview

This is a Siemens QBM68.2500D, a differential pressure sensor from Siemens's QBM series for air and non-aggressive gas applications. Built for demanding accuracy requirements with a diaphragm sensing element and ambient temperature compensation, it delivers consistent, precise pressure measurement across a 0–2500 Pa range, with data available via both Modbus RTU communication and a standard 0–10V analog output for flexible system integration.

Key Features

  • High measurement accuracy: Total error under ±1% FS, with tight temperature-coefficient specifications for both zero point (<±0.1% FS/°C) and sensitivity (<±0.06% FS/°C).
  • Ambient temperature compensation: Maintains consistent measurement accuracy even as ambient conditions fluctuate.
  • Dual output options: Modbus RTU digital communication alongside a 0–10V analog output, supporting flexible integration into existing control and monitoring systems.
  • Low power consumption: Draws under 1 VA, operating from either AC 24V or DC 13.5–35V supply.
  • Sealed, durable housing: IP65-rated protection with brass pressure connection fittings (5mm diameter) and an M16 cable bushing for reliable long-term operation.
  • Easy installation: Compact design supports quick setup, minimizing installation time and cost.
