摘要:
The present invention relates to a pressure control device, in particular for motor vehicle braking systems, with at least one valve carrier accommodating a pressure control valve, a pressure sensor for detecting the hydraulic pressure in a pressure fluid channel of the valve carrier as well as with an electric module including electric and/or electronic structural members and being connected to the pressure control valve and the pressure sensor by way of electric contacts. The pressure sensor is positioned in a space interposed between the pressure control valve and the electric module, with at least one of the contacts that is connected to the pressure sensor leading through a sensor carrier to the electric module. The sensor carrier is located at least in sections within the space.

There is disclosed a measurement mechanism for differential pressure measurement. The mechanism has two housing portions with flanges. A differential pressure sensor is force-fit between the two flange faces. An electronics board is connected to the differential pressure sensor by means of a force-fit electrical contact.

A pressure sensor of a pressure-sensor module is connected to a wet space in a vehicle door by a through-passage channel of a sealing cushion and a connecting branch, which is guided with sealing action through a partition. A housing of the sensor module is located in a dry space. An interior of the housing and the dry space are sealed in relation to the interior of the connecting branch, with the result that a water-tightness of the housing, in which a printed circuit board and electronic components are accommodated, does not have to meet high requirements.

A pressure sensor device having high reliability and excellent workability, which can be used for both types of sensor elements which receive pressure on the front side and the rear side, can be reduced in size, whose characteristic properties can be confirmed before a sensor module is set in the case, and which eliminates the need for changing the internal structure of the case when the external shape of the case or the shape of a connector is altered. A wall portion projecting to surround a sensor element is formed on the surface of a sensor module, a groove potion is formed in an upper case or a lower case at a position corresponding to the wall portion, and an end of the wall portion is mated with this groove portion through an adhesive to form a closed space for storing the sensor element.

An improved pressure sensor assembly incorporates a stainless steel pressure sensing element that is welded to a stainless steel pressure port insert-molded into a molded plastic pressure vessel. Sealing between the pressure port and the pressure vessel is enhanced by a O-ring seated in a groove on the outer periphery of the pressure port, or by a sealant applied to the periphery of the pressure port prior to the insert molding operation. The pressure port is insert-molded with the pressure vessel so as to expose an axial end of the pressure port having a stepped annular surface, and the pressure sensor element is welded to the exposed end of the pressure port. The plastic material of the pressure vessel extends into a central axial bore of the pressure port to minimize leakage by maximizing a potential leakage path for the medium contained by the pressure vessel, and over a shoulder of the pressure port to secure the pressure port in the body of the pressure vessel.
摘要:
The type of a pressure sensor is automatically identified even when the input/output lines of the pressure sensor are three lines, i.e., power source lines (two of + and −) and a voltage output line for outputting a voltage corresponding to an applied pressure. The current value Ip, which flows through the power source lines of the pressure sensor, is made to be a different value depending on each type of the pressure sensor. A voltage value Vr (Vr=Ip×Rr, where Rr is a resistance value of a resistor) is measured by using a differential amplifier, and the voltage value Vr is compared with a voltage range previously recorded in ROM. Accordingly, the type of the pressure sensor can be automatically identified by using a microcomputer.
摘要:
An apparatus measuring the temperature and/or pressure of an exhaust gas plume from a supersonic military jet engine. The apparatus includes a rotatable airfoil having one or more sensors that are impinged by the exhaust gas flow path prior to the exhaust gas flowing over the airfoil. At least one base is attached and adapted to be mounted to a supporting surface for locating the airfoil rearward of the exhaust gas plume.

A pressure measuring system has a line through which a fluid (4) flows, the line (3) having a central line section (5) in which, on a flattened outer side (6) of the line (3), a diaphragm is provided. The movements of the diaphragm, which are characteristic of pressure changes, are transmitted to a pressure sensor. In this case, the diaphragm is nondetachably connected to a protrusion (10) which points away from the line (3) and has an extension (12) which is oriented substantially transversely with respect to the longitudinal alignment of the line section (5) and, in a mechanical and simultaneously detachable way, acts on a force sensor as pressure sensor. A pressure measuring system is therefore provided which can be used for reconditioning in the autoclave sterilizer.
摘要:
A method for determining the suction pressure of a centrifugal pump including the steps of determining pump torque and pump discharge pressure at at least two different speeds, forming a first order wave curve as a straight line using said pump torque and pump discharge and determining suction pressure from the y axis intercept of said line.

Disclosed is an apparatus and method of pressure testing an installed pipe by inserting a fitting into the internal threads found in saddle tee fittings. The internal threads of the fitting used by the cutting mechanism may allow a common apparatus to be used across different manufacturer's fittings without modification. Further, the device has a certain length of thread engagement to allow for proper engagement while maintaining the load carrying capacity required to properly perform the pressure test.
