摘要： A pressure gauge includes: a pressure sensor; a display unit configured to display a measurement value of the pressure sensor; and a measurement controller configured to set, as a measurement range of the pressure sensor, any of a plurality of measurement ranges defined by a lower limit value specific to the pressure sensor and respective upper limit values that are equal to or lower than an upper limit value specific to the pressure sensor and are different from each other, and to avoid that the display unit displays the measurement value when the measurement value exceeds a display upper limit value dependent on the upper limit value of the measurement range that is set.

摘要： An elongated apparatus that measures soil water tension is disclosed, having a hydrogel chamber for receiving a plurality of macro-sized hydrogel particles through its open side and a sealed inner wall, the hydrogel held in the hydrogel chamber by a durable, hydrophilic, and porous window secured to the open side of the hydrogel chamber. The window, when the apparatus is received in soil, transmits moisture between the soil and the hydrogel chamber, causing variable pressure within the hydrogel chamber that can be converted to a measurement of soil water tension on the opposite side of the window. This pressure produces various mechanical effects, measurable by various types of sensors within the elongated probe. A method for measuring soil water tension at multiple depths within a soil profile is also disclosed.

摘要： Intelligent temperature and pressure gauge assemblies (52) for use with vessels (24) having pressurized hazard suppression materials therein include temperature and pressure sensors (136, 138) coupled with a digital processor (72) with associated memory for storing empirical temperature and pressure data. The data includes normalized linear temperature-pressure curves consistent with static or slowly changing temperature conditions experienced by the vessels (24), as well as nonlinear temperature-pressure curves consistent with rapidly changing temperature conditions. In use, the assemblies (52) repeatedly sense the temperature and pressure conditions of the hazard suppression material and compare these sensed values with the stored values, and generate an output in conformance with the comparison. In this fashion, the assemblies (52) compensate for rapidly changing temperatures without generating false failure signals.

摘要： A pressure detecting device is mounted in a measurement target and instrument includes a strain inducer to which pressure of a pressure medium is applied and which generates strain in accordance with the pressure and a strain detecting element that is bonded onto a surface opposite to a pressure receiving surface of the strain inducer, in which the strain detecting element includes one or multiple central strain resistant bridges which are arranged at a central portion of the strain detecting element in a bonded surface direction, and one or multiple outer peripheral strain resistant bridges which are arranged at an outer periphery, and in which, for example, deformation of the strain detecting element caused by an external force when being screw-fixed to the measurement target instrument is obtained through the multiple strain resistant bridges. An error of detection pressure caused by the deformation in a pressure value detected through the central strain resistant bridge is corrected.
