Differential pressure transmitters from halstrup walcher are used for regulating HVAC systems and for monitoring filters. The devices can also monitor under- and overpressures in cleanrooms or mini-environments. halstrup-walcher now offers the new PS17 differential pressure transmitter – a device with useful options and features, and suitable for basic applications.
The PS17 measures differential pressures between ± 50 Pa und ± 10 kPa. The measurement precision of the piezoresistive silicon sensor system is extremely high at ± 1% of the final value and remains highly stable over the long term – a marked improvement over its predecessor, the PS27. The switchable version of the PS17 allows customers to select the right measurement range from four different options. In addition, the output signal can adjusted within a range of 0/4 .. 20 mA or 0/2 .. 10 V via a DIP switch, or, if desired, as a root-extracted characteristic curve. Users can also fine-tune the final value by ± 5% and perform zero-point calibrations by pressing a button on the interior of the housing.
The new, robust housing snaps into place, making it easy to open – and that saves time. Two horizontal and vertical holes drilled into the housing exterior allow users to mount the unit on a wall without a mounting plate. The device can also be easily mounted on top-hat rails. Its protection class of IP 65 means that the PS17 can be used indoors or out.
The instrument comes with several options: in addition to a relay or measurement display, the PS17 can also be equipped with a DC/DC converter, making it suitable for applications requiring galvanic separation. Delivery can also include certificates of calibration, either from DAkkS (Germany's national accreditation body) or from the company's own laboratory. The halstrup-walcher service team will also be happy to provide support if you have any questions or would be interested in calibration or adjustments.
