    Abstract: The invention provides a restriction element for a pressure sensor to protect the pressure element from flow related damage. The pressure sensor comprising a housing with a fluid inlet channel and a chamber with a pressure element. The pressure element comprises a housing part with a recess covered by a sealing diaphragm forming a cavity. In the oil-filled cavity a sensor element is placed. The restriction element is placed in front of the sealing diaphragm protecting the pressure element and especially the sealing diaphragm from a damaging pulse or other flow related damages caused by sudden changes in a flow system for example by closing a valve.

    Abstract: A method for calibrating a superheat sensor (5) for a refrigeration system is provided. The method comprises the following steps. Increasing an amount of liquid refrigerant in the evaporator (1), e.g. by increasing an opening degree of the expansion valve (3). Monitoring one or more parameters, e.g. the temperature of refrigerant leaving the evaporator (1), said parameters reflecting a superheat value of the refrigerant. Allowing the value of each of the parameter(s) to decrease. When the value(s) of the monitored parameter(s) reaches a substantially constant level, defining the superheat value corresponding to the constant level to be SH=O. The superheat sensor (5) is then calibrated in accordance with the defined SH=O level. When the parameter(s) reaches the substantially constant level it is an indication that liquid refrigerant is allowed to pass through the evaporator (1), and thereby that the superheat of the refrigerant leaving the evaporator (1) is zero. Calibration can be performed on site, and it is therefore not necessary to calibrate the sensor (5) at the manufacturing facility. Thereby it is no longer required to match calibration information with a specific sensor.

    Abstract translation: 提供了一种用于校准用于制冷系统的过热传感器（5）的方法。 该方法包括以下步骤。 增加蒸发器（1）中的液体制冷剂的量，例如 通过增大膨胀阀（3）的开度。 监测一个或多个参数，例如 离开蒸发器（1）的制冷剂的温度，所述参数反映制冷剂的过热值。 允许每个参数的值减少。 当所监视的参数的值达到基本上恒定的水平时，将对应于恒定水平的过热值定义为SH = O。 然后根据定义的SH = O电平校准过热传感器（5）。 当参数达到基本上恒定的水平时，表明允许液体制冷剂通过蒸发器（1），从而使离开蒸发器（1）的制冷剂的过热为零。 校准可以在现场执行，因此无需在生产设备中校准传感器（5）。 因此，不再需要将校准信息与特定传感器相匹配。

    Abstract: The invention provides a pressure sensor with a housing for a pressure sensing arrangement, e.g. a semi-conductor arrangement. The housing consists of a bottom part and an intermediate member with a through hole forming a sidewall of a cavity for the pressure sensing arrangement. A membrane is attached to the intermediate member to cover an opening of the cavity, and to allow pressure from outside to propagate into a pressure transmitting medium contained inside the housing and thus to the pressure sensing arrangement therein. The invention also provides a method of making a pressure sensor with a housing of the above-described kind.
