Siemens QBM3020 Differential Pressure Sensor
KSh 18337 – KSh 18663
Siemens QBM3020 Differential Pressure Sensor uses a diaphragm sensing element and provides high range pressure measurement with accuracy and an output of 4 to 20 mA. Available with switchable pressure-linear or extracting-the-root characteristic and digital display. With the extracting-the-root characteristic, the pressure measuring range is adjustable.
Applications: Measuring pressure in ventilation, Air conditioning ducts & Pressure supervision in labs, Checks air flows, HVAC, Control fans & Cleanrooms
Siemens QBM3020 Differential Pressure Sensor is used to acquire differential, over and under the pressure of air and nonaggressive gases in applications where a high degree of measuring accuracy and quality is essential. Siemens Differential Pressure Sensor will be appropriate for measuring volume flow via differential pressure since the output signal can be set to extracting the root.
Features Of Siemens Differential Pressure Sensor:
- The high degree of measuring accuracy.
- Adjustable characteristic curve (pressure-linear or extracting-the-root).
- Zero-point adjustment
- Simple and fast mounting thanks to integrated fixing angle bar in the housing
- Maintenance-free thanks to excellent long-term stability
- Calibrated and temperature-compensated measuring signal
- Supplied with plastic tubing
- Very short response time
