Embodiment
Electron pressure switch shown in Fig. 1 and 2 comprises shell body made of aluminum 1, and this shell body has the cylindrical cavity 60 of band longitudinal fluting 61, its further groove 61 with can extract circuit board 2 and can engage with extracting.
Bottom at described shell body 1, be fixed with steel flange 90, in this flange 90 chamber 91 is arranged, the pressure sensor of band Ceramic Balls 8 and corresponding packing ring 9 is anchored in the chamber 91 by collar nut 80 and meson 81, be provided for connecting the threaded outlet 92 of pressure system under it, wherein be useful on the inside access road 95 of Be Controlled fluid.
Described flange 90 is separable with shell body 1, and its material resistance is than shell body 1 height usually, thereby can be operated in very under the high workload pressure.This flange can replace according to the flange that required operating pressure is made by other materials in addition.
Described circuit board 2 supports has the trigger mechanism 4 that key 12-13 is set, indication light-emitting diode 16 sends green glow, indication light-emitting diode 11 sends ruddiness, and the serial port 14 with connecting pin 15 is used for being connected with external personal computer or other data input/gathering-devices by electric wire 65.
The operator can touch described key 12-13 by the threaded openings 73 relative with the head of shell body 1, and usually opening 73 can be removed by screw thread and cover 74 and close.
On circuit, described circuit board 2 comprises main circuit 17 (Fig. 3), supplies with and protective circuit 18 (Fig. 4), is used to amplify the circuit 19 (Fig. 5) from the signal of pressure sensor 8.
Main circuit 17 comprises respectively by the switch 20-21 that key 12-13 control is set, has internal electrical Erasable Programmable Read Only Memory EPROM (E
2Prom memory) and the microprocessor 33 of feedback capacity 32, commutation transistor 34, power transistor 35, light- emitting diode 11 and 16, several resistance 22 are stablized electric capacity 31, voltage stabilizing didoe 60, ground connection, input 36 and output 37.
Supply and protective circuit 18 comprise a pair of input 45-46, are used to prevent the diode valve 42-43 of voltage direction, variable resistor 41, electric pressure converter-stabilizer 40, resistance 38, electric capacity 44 and a plurality of ground connection.
At last, amplifying circuit 19 comprises: the input 70 of Wheatstone bridge 72 and output 71, and wherein pottery grain 8 is parts of this Wheatstone bridge 72, two operational amplifiers 50 and 51, with the output 52 that the input of Fig. 3 circuit part 17 is connected, diode valve 53 and various ground connection.
Manually being provided with of pressure switch is very simple.
Yellow light-emitting diode 10 is associated with the power circuit (Fig. 3-5 does not show) of pressure switch, is used to indicate the power supply energising.
Suppose that pressure switch is installed on the controlled system or equipment, and control by the triggering pressure (for example 7 crust) of desired value.This pressure is surveyed by ceramic sensor element 8, this has caused the imbalance of Wheatstone bridge 72, this is converted into the signal of telecommunication that has and be detected the respective amplitudes of pressure, by output 52 outputs of the amplifying circuit 19 of Fig. 5, and the input 36 of the microprocessor 33 of the circuit part 17 of input Fig. 3.
In order to touch the described key 12-13 that is provided with, only need remove lid 74.Needn't stop the system or equipment of Be Controlled pressure.The power supply energising of pressure switch is shown by the yellow light-emitting diode on the connector 6 10.
By keeping key 12 to depress at least 3 seconds, the magnitude of voltage of input 36 is obtained as trigger value by the memory of microprocessor 33, and green LED is luminous as a result.
The acquisition of each new excitation values also is provided with automatically according to lagging voltage value minimum value and removes threshold values (hysteresis).
For different contact threshold values is set, must make system under required pressure relief and 13 at least 3 seconds of depressible keys.In this case, two green LEDs 16 are luminous, confirm the acquisition of releasing value to represent microprocessor 33 and relational storage.
In case pressure switch triggers, opening 73 can be covered by lid 74 once more.
During operation, the red light emitting diodes on the connector 6 41 is luminous is used to indicate trigger value to arrive.Then saturated or at blocking state, with by electric wire 65 index signal to the outside, pressure switch is in triggering state or disarm state to transistor 34 and 35 by microprocessor 33 exchanges.
Programming is somebody's turn to do once more if desired, only needs repeat above-mentioned program with different force value.
Obtaining new value (trigger or remove) before, E
2Test on the prom memory.Before the optical signal that obtains data, this is by a series of fast blink indications of green LED 16.
Except significant setpoint adjustments rapidly, described pressure switch is very flexible, by while depressible keys 12-13 several seconds,, mode of operation is converted to mode of operation " normally closed " contact (being that output 37 has signal usually) so that " often opening " contact (be among Fig. 3 output 37 do not have signal usually).In the practice, two pressure switches form one.
The operating pressure of ceramic particle 8 detection systems if this has surpassed trigger value, produces the imbalance of Wheatstone bridge 72 among Fig. 5, and the result is by the output 52 of Fig. 5 and the input 36 of Fig. 3, and input pressure signal is given microprocessor 33.The blocking-up of oxide-semiconductor control transistors 34 then causes the blocking-up of power transistor after the latter.The Red LED1 11 of diode valve 41 controls is bright.
Opposite action, promptly closing of transistor 34 and 35 saturated and red light emitting diodes 11 recovers to determine by removing threshold values pressure down.
At last, key 12-13 is set and is used for introducing design locking/unlocking coding.The operator can carry out trigger action, if he know and pre-set uniting of key 12 1 13 (for example key 12 must be by twice, key 13 once, key 12 is again by three times).Such coding is by the software control that is integrated on the circuit board 2.
Therefore can under safest situation, trigger the groundwork parameter rapidly and avoid frequent maintenance according to pressure switch of the present invention.
