Datasheet HT01 HUBER INSTRUMENTE AG, Grellingerstrasse 23, CH-4208 Nunningen - Clean room technology - Finishing pass measurement - Filter monitor - Heating – Ventilation – Air conditioning HUBER INSTRUMENTE AG, Grellingerstrasse 23, CH-4208 Nunningen The microprocessor-controlled pressure transducers of the HT01 type series are suitable for detection of excess pressure, low pressure or differential pressure of non-aggressive gasses. Pressure measurement is carried out via a piezoresistive pressure sensor. The sensor is available with two different basic pressure ranges. These ranges may be subdivided by means of the DIP switch. The temperature drift of the sensors is compensated individually. The wear-free measurement system allows for almost maintenance-free operation. The integratred electronic system provides a pressureproportional analogue voltage signal (0 ... 10 V) and a current signal of 0 ... 20 mA. This signal may be switched to 4 ... 20 mA. For strongly varying pressures a dampening function is included. This function may be switched from approx. 10 ms (retardation) to 2 sec. or 4 sec. by means of the DIP switch. An LC display is optionally available and may be retrofitted by means of patch system.
