Many years experience of supplying Differential Pressure Transmitters Halstrup Walcher Gmbh have many years experience of supplying Differential Pressure Transmitters for applications where it is necessary to maintain a continuous overpressure; e.g. in hospitals, cleanrooms, and hygienic plants. It can also be necessary to maintain continuous underpressure to prevent bacterial spread in isolation wards. We can offer a range of high precision devices to suit these applications, but for the basic requirements of HVAC our PS27 series unit offers a competitive alternative. This compact unit is available with two-wire technology and an optional display. Four different measurement ranges can be selected by toggling, or by jumpers, and a range of analogue outputs can be selected. With such a large number of Differential Pressure units out in the field the need for a high precision all in one measurement and calibration device becomes apparent. The KL200 runs on mains supply or battery and is ideal for mobile applications. An internal pump quickly and accurately generates positive or negative differential pressure up to 100kPA. Multilingual with USB interface. Suitable for calibration of blood pressure monitors. Twenty ranges up to 100kPa.
