Abstract
The utility model relates to a pointer type manometer with a critical pressure signal output unit, which comprises a pointer manometer pointer, a dial, a transparent cover plate, etc. The utility model is characterized in that the critical pressure signal output unit is provided with at least one sensing probe on the area for the deflection of a pointer on the dial in the transparent cover plate, the sensing probe is provided with a metal contact touch type sensing electrode or a contactless optical magnetic sensor, a meter pointer is a metal electrode or an optical magnetic sensor triggering device, when the pointer and the sensing probe contacts or approach to the bottom, sensing signals are output and a conductor wire is externally connected with an alarm and action executive device.
Description
The utility model relates to the improvement to pressure pointer instrument.
The existing instrument that is used to measure air pressure is a drum-type pointer pressure gauge, pointer indicates container, the pressure of pipeline is as being used for the gaseous tension that commercial production (especially industry such as chemical industry) indicates various operations or storage, the steam pressure of boiler, the air pressure of indication oxygen and confession used for respirators in medical treatment, be used for the negative pressure indication of drainage etc., the air pressure range of the various model indications of these pointer instruments is from 10
-4-10MPa need conscientiously monitor the air pressure and the medical gaseous tension of industry and boiler, diverts one's attention when the overseer to grow; Big psychological pressure is arranged.At present, yet there are no and simply be used in reference to the manometric emergent pressure signal output apparatus of pin type.
The utility model purpose is to make a kind of pointer pressure gauge that has the emergent pressure signal output apparatus.
Technical solution of the present utility model is to comprise pointer pressure gauge pointer, compositions such as dial plate transparent cover plate, it is characterized in that emergent pressure output signal device is equipped with a pickup probe at least in transparent cover plate on the area of needle deflection on the dial plate, hard contact contact-sensing electrode or contactless magneto-optical sensor are housed on the pickup probe, list index corresponds to metal electrode or magneto-optical sensor flip flop equipment, pointer touch mutually with pickup probe or near the time output transducing signal and connect external warning or action actuating unit by lead.
Further solution of the present utility model is: pickup probe is fixed on the transparent cover plate with pointer is coaxial, the stationary installation of recommending has a bar to pass the coaxial aperture of sensing pointer and transparency cover plate hole and swing handle to fix, holddown spring also is housed on bar, like this, swing handle drives sensing pointer desired location, the sensing indicator device is contained on the existing pressure gauge, and existing manometric film drum pointer structure all need not change, and does not influence existing metering.
The utility model is simple in structure, sensor construction can be various, sensor directly spreads out of the emergent pressure signal of the setting of pointer indication, former pointer pressure gauge does not make any changes, warning device or action actuating unit conveniently are contained in any position that makes things convenient for, and the utility model can be used for various critical high-low pressures reports to the police, and is used for vapor pressure during as high pressure, air pressure minimum detectable signal indication is used on the gauge outfit of medical welding bottle and the Medical Instruments of Central oxygen-supply tensimeter and vacuum suction etc. during low pressure.
Be described further below in conjunction with accompanying drawing and by embodiment:
Fig. 1 is the utility model sectional view, and Fig. 2 is an alerting signal embodiment circuit diagram
Sensor 8 is housed on the pickup probe 3, sensor is a metal electrode, then metal finger also polishes and exposes metal, the sensor 14 of pickup probe also can be visible light, infrared emission is accepted pipe, pointer is a shielding plate, cover sensor gap 15 and can be magnetic material and Hall sensor, pointer corresponds to the irony matte.There is line to be connected to external circuit or action actuating mechanism on the sensor, when shielding plate passes through the gap, the signal that blocking added originally, sensor output signal drives external circuit.The hole 20 of transparent panel is greater than the diameter of swing handle 1, other has a supporting plate to be fixed on the panel by screw rod and carrier base, screw rod 7 passes packing ring 2, and the hole is fixed on the swing handle on the hole 18 of holddown spring 5 and supporting plate and the pickup probe, and swing handle has lock hole, post 21,22 to cooperate with probe.
As being metal electrode contact alarm, Fig. 2 has provided the circuit diagram of this electric alarms based on pattern recognition on the pressure gauge, A point in pointer hard contact (the metal finger side coat of paint is ground off) connection layout 2, and general purpose pressure gauge (range IMP) pointer is communicated with shell; The B point connects metal electrode contact on the pickup probe, when A, B connect, and the entire circuit power connection, 555 vibrations drive hummer Y sounding, and the contact output signal can be connected the amp.in signal.Non-contact sensor from the pickup probe directly output signal trigger warning circuit or relay switch like making in the box that the fritter printed panel is contained in pressure gauge connects for the simple alarm circuit.Need preset parameter to report to the police or the pressure gauge of action for certain, can be in panel degree fixed position fixing pickup probe.The device that another kind of adjustable parameter is reported to the police is a groove of opening a circular-arc fixedly pickup probe on panel.
Claims (4)
1, the pointer pressure gauge that has the emergent pressure signal output apparatus, comprise pointer pressure gauge pointer, compositions such as dial plate transparent cover plate, it is characterized in that emergent pressure output signal device is equipped with a pickup probe at least in transparent cover plate on the area of needle deflection on the dial plate, metal is housed on the pickup probe can puts contact-sensing electrode or contactless magneto-optical sensor, list index corresponds to metal electrode or magneto-optical sensor flip flop equipment, pointer touch mutually with pickup probe or near the time output transducing signal and connect external warning or action actuating unit by lead.
