PS 27 德国halstrup walcher 微差压变送器

 basic sensor for simple applications - mounting on top-hat rails.
the ps 27 differential pressure transducer is a basic sensor for simple applications with very little hysteresis, temperature dependence or zero-point drift.in addition to differential pressure data, the ps 27 also records positive and negative overpressures, and is suitable for measuring air and all non-aggressive gases. zero-point calibration can be performed via an external control signal. a jumper is available for selecting the output signal.

a built-in adapter for top-hat rails allows the ps 27 to be mounted on top-hat rails (e.g., in a control cabinet) with no additional accessories re with the optional switching output, a visual or audible alarm can be triggered whenever values fall above or below a threshold parameter. the ps 27 is a simple, precise pressure transducer for applications in areas such as air-conditioning and ventilation technology. protection class: ip 65.
