P 26.2
Differential pressure transmitter P 26.2 with scalable measuring range and a high level of overpressure protection
Pressure Transmitter with High Accuracy, Scalable Measuring Range, and High Overload Protection
Special features
- High-precision differential pressure transmitter for cleanroom, HVAC, and process technology
- Precisely matched measuring ranges starting at 10 Pa, uni- and bidirectional
- No zero-point drift thanks to automatic zero-point adjustment
- Easy commissioning and flexible installation (top-hat rail and wall mounting)
- Multiple switching and analog outputs as standard
- Extensive configuration options via parameterization software through internal USB-C interface
The P 26.2 pressure transmitter is particularly suitable for pressure monitoring in cleanrooms, laboratories, pharmaceutical facilities, operating rooms, as well as for special applications in mechanical and plant engineering. In addition to differential pressure, the device also measures positive and negative overpressure as well as flow velocity or volume flow. The measuring ranges are scalable from 10 to 100%. A selectable time constant allows optimal adaptation of the transmitter to the pressure conditions, ensuring a stable output signal. The pressure transmitter is CE-/UKCA-certified as standard; selected variants are available with NRTL certification according to UL / CSA 61010-1.
Options
- The P 26.2 pressure transmitter is optionally available with a factory calibration certificate or a calibration certificate according to DKD guideline 6-1.
- Two optional switching contacts allow the connection of optical or acoustic alarms when limit values are exceeded or not reached.
- The pressure transmitter can be easily configured via an optional USB interface using software.
- Alternatively, configuration can also be performed via keypad and display. The measured value can be displayed in all common units, and a color change can be selected for alarm indication.
