Siemens QBE63-DP02 Differential Pressure Sensor — 0-20 kPa, Pair
Hall-effect differential pressure sensor for liquids and gases, DC 0-10V output — priced per unit
Overview
The Siemens QBE63-DP02 measures differential pressure via an EPDM diaphragm that deflects a spring; as the diaphragm moves under pressure, a permanent magnet attached to it changes position relative to a Hall-effect transducer on the outside of the housing, which delivers an electrical signal proportional to the magnetic field. This signal is linearized, temperature-compensated, and amplified by the sensor's built-in electronics, and can be used with any device or system capable of processing the DC 0-10V output. Suitable for slightly aggressive liquids and gases, the sensor is highly resistant to overpressure and features G1/8" threaded connections, though it is not suitable for use with ammonia or freons. This listing covers 2 units, sold per unit.
Key Features
- Hall-effect measurement: Diaphragm-driven magnet position sensed by a Hall-effect transducer for accurate, linearized pressure readings.
- Temperature-compensated output: Built-in electronics linearize and temperature-compensate the signal for stable measurement across the rated medium temperature range.
- Standard DC 0-10V output: Compatible with any control system or device capable of processing a 0-10V analog signal.
- High overpressure resistance: Rated for max. permissible pressure of 10 bar, well above the 0-20 kPa measuring range.
- IP65 protection: Suitable for demanding industrial and mechanical room environments.
- Flexible mounting: Can be installed in any position, with G1/8" threaded connections for direct pipe/system installation.
- Included mounting bracket: Supplied complete with a mounting bracket for convenient installation.
