Abstract: A flowmeter includes a heating resistor and a resistive element for detecting the temperature of the heating resistor. The heating resistor is controlled so that the temperature detected by the resistive element approaches a reference temperature determined based on the temperature of the fluid flow. As a result, the temperature of the upstream side of the heating resistor becomes lower than the reference temperature, while the temperature of the downstream side of the heating resistor becomes higher than the reference temperature. Another resistive element is arranged on the upstream side or the downstream side of the heating resistor for detecting the rate of the fluid flow, and the rate and the direction of the fluid flow are detected by comparing the temperature of the resistive element with the reference temperature. This flowmeter is immune to variation in the resistance of the heating resistor.

Abstract: In a sensor attachment structure, a lead wire connecting a sensor is pinched in a pinch portion provided at a tip side portion of an extending bar, proximate to the sensor. The pinch portion has a protrusion that protrudes from the end surface of the pinch portion toward the sensor. A contact surface of the protrusion is inclined toward the sensor from a protruding direction of the pinch portion to have an inclination angle equal to or larger than a deflection angle that is formed at the tip side of the extending bar against the extending direction of the lead wire. Accordingly, even when a tensile force F is exerted to the lead wire opposite to the sensor side, a component force of the tensile force F along the contact surface becomes zero or is directed to the base of the pinch portion.

Abstract: A pressure indicator according to the present invention monitors the pressure of the fluid in a vessel. One embodiment of the present invention comprises a closed pressurized gas volume behind a dimpled metal diaphragm. In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm overcomes the force of the gas pressure acting on the internal surface of the diaphragm to hold the diaphragm in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of the diaphragm will overcome the force of the fluid pressure acting on the external surface of the diaphragm, thereby moving the diaphragm into a convex geometry. A viewing window disposed in the side of the vessel can be used to view the pressure indicator and determine the shape of the indicator diaphragm.

Abstract: The present invention provides a pressure sensing device that includes at least one TMR sensor, and preferably an array of TMR sensors, with each TMR sensor having an insulating spacer layer interposed between a pinned and a free ferromagnetic layer. In an unbiased state, the magnetization vector of each of the ferromagnetic layers is preferably parallel to each other. Upon application of a small voltage, the magnetization vectors remain unchanged. Upon application of stress, the magnetization vector of the free magnetic layer will rotate, thus causing a corresponding and proportionally related change in the resistance of the sensor. This change in resistance can be sensed and used to calculate the stress applied thereto.
