A:say all:
HH3351 series electric capacities changing to send a machine is the new generation high performance intelligence pressure/differ to press to change to send a machine.Have principle of design novel,the species specification is well-found and install to use a simple and safe and flameproof etc. characteristics.Combine accuracy is high,the physical volume is small,the weight is light,the fastness bear to flap,adjust convenience,long-term stability good,one-way lead carry the protection ability strong but the call.Extensively applied in professions, such as electric power,petroleum,chemical engineering,metallurgy,light work,medicine and environmental protection...etc..Its category include:Differ to press,the form press,press extremely,the liquid and Far EasTone Telecommunications Co., Ltd etc. change to send a machine, can use various industrial environment, is 1151 change to send to a machine to get stripe to change a product.
Two:technique characteristics
1:BE measure to lie quality:air,liquid,steam.
2:the quantity distance:0-0.2 Kpa ～ 10 Mpas.
3:the power supply power supply:the 12-36 V DC(standard 24 V DC)
4:output signal:4~20 mAs.
5:the degree:± 0.1%/ ± 0.25%/0.5%
6: The environment temperature:the － is 20-85 ℃s.
7:relative humidity:0 the ～s is 90% RHs.
8:stability:six month error margins is biggest quantity distance of the ± is 0.15%.
9:the conjunction method:M20 ×s 1.5/1/2 NPT outside thread.
10:the 阻尼 :time constant is adjustable between the 0.2-32.0 Ss.
11:heavy quantity:3.5 Kgs(DO not include an enclosure)
Three:the application realm:
1:in addition to have 1151 of characteristics, also have as follows a characteristics
2:the usage intelligence of the microprocessor change vivid of send the machine to enlarge,the function strengthen
3:the intelligence electronics parts is only constitute by a piece of circuit plank, the superiority is stronger, the credibility is higher.
4:right on the spot the key adjust zero:00 and quantity a distance.
5:can renew ready-made various 3351 imitate a type to change to send a machine to change to send a machine for the intelligence.
6:match the HART agreement, can carry on a double toward communication but don't break off to output signal with the HART communication machine and this intelligence form.
7:have from examine a patient to examine a patient function and long range.
8:take EEPROM, the power failure doesn't throw to lose a data behind
Four:install a method
Differ to press to change to send a machine if direct install in measuring to order, can be prop up by the conjunction tube, can also install on the dial to use gearing support to install it perhaps on 2 ″ pipes.For insuring to deal with contact of seal completely, while seal completely should press nether step operation;At tightly solid two stud bolts, should replace to use the wrench 拧 tight, it end 拧 tight dint about is 40 Ns.M, absolutely not to a 拧 is tight bolt.Sometimes for install up of convenience, change to send the machine essence up of the pressure permit room and can turn to move.As long as the pressure permits room to be placed in perpendicular side, then changing to send to the machine essence to turn to move will not produce zero varieties.If the pressure permit When the room level install, have to remove because of leading to press different but causable liquid pillar of the tube height to press the influence of the head, namely heavy adjust to change zeros of send the machines.
Changing to send a machine can ask for help three kinds of gearing planks in of a kind of, install on the wall or the piping with 50 mms mms-60ses up, install as long as make to change to send the machine surface perpendicular ground, change to send a machine to make any position variety in spite of at this time, will not cause zero drifts.If can't keep to change to send a machine perpendicular, will cause zero small varieties, but re- check and adjust zero after changing to send the machine gearing fixedly, accuracy still canned attain provision. |
