Abstract:
A second case includes a projection that projects on an opposite side of a threaded portion of the second case, which is opposite from a first case, while the projection is placed in a passage when the second case is installed to an installation-subject member. An opening is formed in a visible area of an outer peripheral surface of the projection, which is visible at a time of viewing the outer peripheral surface in a flow direction of the measurement-subject medium upon installation of the second case to the installation-subject member, and the projection includes a flow direction changing portion that changes a flow direction of the measurement-subject medium, which is introduced from the passage into an introducing hole through the opening, from a direction along the passage to a direction toward the sensor unit.
Abstract:
A measurement system for monitoring ambient temperature and airspeed is disclosed. The measurement system uses a single temperature sensor, disposed in the environment under test, in communication with a controller. The controller supplies a first current to the temperature sensor to measure the ambient temperature of the environment. This first current is selected so that it results in little or no self-heating of the temperature sensor. After the ambient temperature is determined, a second, higher current is applied to the temperature sensor. This higher current serves to heat the temperature sensor be a predetermined amount. Based on the expected temperature rise, the ambient temperature and the actual monitored temperature, the airspeed may be determined.
Abstract:
An aspirator is provided that includes a nozzle that aspirates secondary air; a main body that forms a scroll-shaped airflow path on the outer circumference of the nozzle; a primary-air inflow path that tangentially communicates with the airflow path; and a diffuser that is connected to an open end of the main body and has a throat portion at which a tip portion of the nozzle is disposed. An inner wall of the primary-air inflow path, which communicates with the scroll-shaped airflow path, is offset outward from the center of the nozzle, and primary air introduced from the primary-air inflow path flows into the scroll-shaped airflow path from one direction.
Abstract:
An outside air temperature measurement device and method for vehicles derives a useable final value of the outside air temperature within seconds of the beginning of vehicle movement by developing a mathematical expression (i.e., model) for the exponential data series while discriminating against thermal noise components existing in the measurement data.
Abstract:
A temperature detector for measuring temperature of a heat exchanger of a vehicular air-conditioning unit includes a holder holding temperature measuring means for measuring the temperature of the exchanger and a harness connected to the measuring means. The holder has a through hole through which a measuring section of the measuring means extends, and first and second grip parts through which the harness extends. The first grip part has such a width dimension that the harness having a width dimension in the horizontal direction can be inserted therethrough, and the second grip part has such a width dimension that the harness having the width dimension in the vertical direction can be inserted therethrough and that the harness having the width dimension in the horizontal direction can not be inserted therethrough. Accordingly, a portion of the harness between the first and second grip parts is twisted and held by the holder.
Abstract:
A sensor arrangement (1) for measuring a pressure and a temperature in a fluid is disclosed. The sensor arrangement (1) comprises a temperature sensitive electrical element (3) and a pressure sensing electrical element (6), the temperature sensitive electrical element (3) and pressure sensing electrical element (6) are both coupled to one side of a metallic membrane structure (4,16). The metallic membrane structure is arranged to pass on the temperature of the fluid which is at the other side of the membrane structure (4,16) to the temperature sensitive electrical element (3) and to pass on the pressure in the fluid to the pressure sensing electrical element (6). In this way a combined pressure and temperature sensor is obtained which is applicable in vehicle air-conditioning systems working with CO2 as refrigerant.
Abstract:
A signal (Snormal) is provided to a heat element of a temperature sensor, which is recorded as a step response (Lruh, Lbew). From the difference of the step response compared with the reaction adaptively determined with the temperature sensor at zero air circulation, air flow or no air flow is determined.

Disclosed therein is a water temperature sensor for an air conditioner of automotive vehicles, which is mounted inside an air-conditioning case for measuring the temperature of cooling water, thereby preventing an air leakage from a mounted position of the water temperature sensor, enhancing work efficiency and productivity by reducing the number of components and the number of work processes, and greatly improving a response to heat around the sensor and a degree of precision in temperature measurement.
Abstract:
The device for detection of the temperature in the interior of a vehicle, particularly for an air-conditioning system of a vehicle, is provided with an interior temperature sensor (28) arranged in a housing (18) arranged in or at a wall (12) adjacent to the interior (14) of the vehicle and being at least partially adjacent to the interior (14) of the vehicle, and a radiation sensor (30) detecting solar radiation leading to the heating of the housing (18) of the interior temperature sensor (28). Further, the device is provided with a compensation temperature sensor (36) arranged behind the wall (12) and such that it is thermally decoupled from the interior temperature sensor (28) and detecting the heat of air and/or assemblies behind the wall (12), which leads to a falsification of the measured value of the interior temperature sensor (28). The two temperature sensors (28,36) and the radiation sensor (30) are combined in a common assembly.
Abstract:
In a vehicle air conditioner, a non-contact temperature sensor is used as a temperature detecting device. The non-contact temperature sensor has a plurality of temperature detection elements for detecting surface temperatures of a plurality of temperature detection ranges in a vicinity of at least one of seats of a passenger compartment in non-contact. The non-contact temperature sensor is provided in a ceiling portion of the passenger compartment in an arrangement area of the ceiling portion between a front end and a rear end of the one seat in a vehicle front-rear direction. Accordingly, even when the size and seated height of the passenger are changed, the temperature detection ranges can contain the passenger, and a passenger's temperature can be stably detected by using the non-contact temperature sensor.
